The temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at 0 °C (32 °F) and a temperature coefficient α = 0.003851 °C[-1] . ## Thin film resistance sensors (TF): A very thin, ultrapure platinum layer, approx. 1 µm thick, is vaporized in a vacuum on a ceramic substrate and then structured photolithographically. The platinum conductor paths formed in this way create the measuring resistance. Additional covering and passivation layers are applied and reliably protect the thin platinum layer from contamination and oxidation, even at high temperatures. The primary advantages of thin film temperature sensors are their smaller sizes and better vibration resistance. ## Measuring system The compact thermometer measures the process temperature with a Pt100 sensor element (class A, 4-wire). An optional built-in transmitter converts the Pt100 input signal. The version of the device with integrated electronics automatically detects the connection version (IO-Link or 4 to 20 mA). A broad portfolio of optimized components for the temperature measuring point is available to ensure seamless integration of the measuring point: - Power supply unit/barrier - Display units - Overvoltage protection - IO-Link master - IO-Link configuration tool For more detailed information, see the brochure "System Products and Data Managers - Solutions for the loop (FA00016K/EN)". _ 1_ **==> picture [356 x 145] intentionally omitted <==** **----- Start of picture text -----**<br> PROFINET/<br>EtherNet/IP<br>IO-Link SPS/PLC<br>Master 1 (L+)<br>2<br>3 (L-)<br>4 (C/Q)<br>IO-Link<br>P=<br>TM311<br> A0039767<br>M12 connection with IO-Link communication mode<br>**----- End of picture text -----**<br> Endress+Hauser 3 iTHERM CompactLine TM311 **==> picture [381 x 179] intentionally omitted <==** **----- Start of picture text -----**<br> 1 (L+)<br>2 (L-)<br>3<br>4<br>12345 SPS/PLC<br>000<br>7 :<br> 2 M12 connection with 4 to 20 mA communication mode, RIA15 indicator and RN22/RN42 active barrier.<br>**----- End of picture text -----**<br> **==> picture [22 x 4] intentionally omitted <==** **----- Start of picture text -----**<br> A0039765<br>**----- End of picture text -----**<br> ## Equipment architecture **==> picture [514 x 290] intentionally omitted <==** **----- Start of picture text -----**<br> Design Options<br>1: Electrical<br>1 connection, [Your benefits:] • M12, 4-pin connector, reduced cost and effort, incorrect wiring is<br>output signal prevented<br>2: Transmitter • Optimum protection, IP69 as standard<br>2 housing • Compact, integrated transmitter (IO-Link and 4 to 20 mA)<br>3: Extension neck Optionally available if process temperature is too high for the electronics<br>4: Process<br>3<br>connection Over 50 different versions for industrial, hygienic and aseptic applications.<br>→ 24<br>5: Thermowell • Versions with and without thermowell (insert in direct contact with process)<br>LJ • Thermowell diameter 6 mm and optimized T-pieces and elbow pieces<br>4 = a ee<br>_ 7<br>\/ 6: Insert with:<br>6a: iTHERM [Your benefits:] • iTHERM TipSens - insert with shortest response times:<br>Vaan TipSens • Insert: ⌀3 mm (¹⁄₈ in) or ⌀6 mm (¹⁄₄ in)<br>6b: Pt100 (TF), • Fast, highly accurate measurements, delivering maximum process<br>— 5 6a ae N N basic safety and control<br>NI • Quality and cost optimization<br>• Minimization of necessary immersion length: better product<br>protection thanks to improved process flow<br>• Pt100 (TF), basic<br>Ny WN • Excellent cost-performance ratio<br>N} IN<br>6b Vi<br> A0039771<br>**----- End of picture text -----**<br> ## Input ||Input|| |---|---|---| |Measuring range|Pt100 (TF) basic|–50 to +150 °C (–58 to +302 °F)| ||iTHERM TipSens|–50 to +200 °C (–58 to +392 °F)| Endress+Hauser 4 iTHERM CompactLine TM311 ## Output ||Output|Output|Output| |---|---|---|---| |Output signal|Order code 020, option A||| ||Sensor output|Pt100, 4-wire connection, class A|| ||Order code 020, option B||| ||Analog output|4 to 20 mA; variable measuring range|| ||Digital output|C/Q (IO-Link or switch output)|| ||Order code 020, option C||| ||Analog output|4 to 20 mA; measuring range 0 to 150 °C (32 to 302 °F)|| ||Digital output|C/Q (IO-Link or switch output)|| ||||| |Switching capacity|• 1 × PNP switch output<br>• Switch state ON Ia ≤ 200 mA; switch state OFF Ia ≤ 10 µA<br>• Switch cycles > 10 000 000<br>• Voltage drop PNP ≤ 2 V<br>• Overload protection<br>• Automatic load testing of switching current<br>• If a current of over 220 mA flows in the ON switch state, the device switches to a safe state<br>• Diagnostic messageOverload at switch output<br>• Switch functions<br>• Hysteresis or window function<br>• NC contact or NO contact<br>• No pull-down resistor is integrated in the device for the switch output.||| |Switch output|Response time ≤ 100 ms||| |Failure information|Failure information is generated if the measuring information is missing or not valid.

Sensor current ≤ 1 mA Calibration Calibration of thermometers Calibration involves comparing the measured values of a device under test (DUT) with those of a more precise calibration standard using a defined and reproducible measurement method. The aim is to determine the deviation of the DUT's measured values from the true value of the measured variable. Two different methods are used for thermometers: - Calibration at fixed-point temperatures, e.g. at the freezing point of water at 0 °C - Calibration compared against a precise reference thermometer Endress+Hauser 10 iTHERM CompactLine TM311 The thermometer to be calibrated must display the fixed point temperature or the temperature of the reference thermometer as accurately as possible. Temperature-controlled calibration baths with very homogeneous thermal values, or special calibration furnaces into which the DUT and the reference thermometer, where necessary, can project to a sufficient degree, are typically used for thermometer calibrations. ## Sensor-transmitter-matching The resistance/temperature curve of platinum resistance thermometers is standardized but in practice it is rarely possible to keep to the values precisely over the entire operating temperature range. For this reason, platinum resistance sensors are divided into tolerance classes, such as class A, AA or B as per IEC 60751. These tolerance classes describe the maximum permissible deviation of the specific sensor characteristic curve from the standard curve, i.e. the maximum temperaturedependent characteristic error that is permitted. The conversion of measured sensor resistance values at temperatures in temperature transmitters or other meter electronics is often susceptible to considerable errors as the conversion is generally based on the standard characteristic curve. When temperature transmitters are used, this conversion error can be reduced significantly by sensor-transmitter-matching: - Calibration at least at three temperatures and determination of the actual temperature sensor characteristic curve - Adjustment of the sensor-specific polynomial function using appropriate Calendar-van-Dusen (CvD) coefficients - Configuration of the temperature transmitter with the sensor-specific CvD coefficients for resistance/temperature conversion, and - another calibration of the reconfigured temperature transmitter with the connected resistance thermometer The manufacturer offers this sensor-transmitter-matching as a separate service. Furthermore, the sensor-specific polynomial coefficients of platinum resistance thermometers are indicated on every calibration protocol where possible, e.g. at least three calibration points. For the device, the manufacturer offers standard calibrations at a reference temperature of –50 to +200 °C (–58 to +392 °F) based on the ITS90 (International Temperature Scale). Calibrations in other temperature ranges are available from your local sales center on request. Calibrations are traceable to national and international standards. The calibration certificate is referenced to the serial number of the device. ## Installation ## Orientation ## Installation instructions No restrictions. However, self-draining in the process must be guaranteed. If there is an opening to detect leaks at the process connection, this opening must be at the lowest possible point. The immersion length of the compact thermometer can considerably influence the accuracy. If the immersion length is too short, measurement errors can occur as a result of heat conduction via the process connection and the vessel wall. Therefore, if installing in a pipe, the immersion length should ideally correspond to half of the pipe diameter. Installation possibilities: pipes, tanks or other plant components.

This results in the following recommended minimum immersion lengths - TrustSens or StrongSens 30 mm (1.18 in) - QuickSens 25 mm (0.98 in) - Wire wound sensor 45 mm (1.77 in) - Standard thin-film sensor 35 mm (1.38 in) Endress+Hauser 12 iTHERM CompactLine TM311 It is particularly important to take this into consideration for T-pieces, as the immersion length is very short on account of their design, and the measured error is higher as a result. It is therefore recommended to use elbow pieces with QuickSens sensors. In the case of pipes with a small nominal diameter, it is advisable for the tip of the thermometer to project well into the process so that it extends past the pipe axis. Installation at an angle (4) could be another solution. When determining the immersion or insertion length, all the parameters of the thermometer and of the medium to be measured must be taken into account (e.g. Flow velocity, process pressure). **==> picture [361 x 137] intentionally omitted <==** **----- Start of picture text -----**<br> A B C D<br>1<br>8<br>2<br>13<br>9 11<br>10<br>3 14<br>12<br>16<br>7<br>4<br>15<br>5 6<br>**----- End of picture text -----**<br> **==> picture [22 x 4] intentionally omitted <==** **----- Start of picture text -----**<br> A0040345<br>**----- End of picture text -----**<br> - _ 7 Detailed installation instructions for hygiene-compliant installation_ - _A Milk pipe connection according to DIN 11851, only in conjunction with EHEDG-certified, self-centering sealing ring_ - _1 Sensor with milk pipe connection 2 Groove slip-on nut 3 Counterpart connection 4 Centering ring 5 R0.4 6 R0.4 7 Sealing ring B Varivent[®] process connection for VARINLINE[®] housing 8 Sensor with Varivent connection 9 Counterpart connection 10 O-ring C Clamp according to ISO 2852 11 Molded seal_ - _12 Counterpart connection D Process connection Liquiphant-M G1", horizontal installation 13 Weld-in adapter_ - _14 Vessel wall 15 O-ring 16 Thrust collar_ ## NOTICE The following actions must be taken if a sealing ring (O-ring) or seal fails: - ‣ The thermometer must be removed. - ‣ The thread and the O-ring joint/sealing surface must be cleaned. - ‣ The sealing ring or seal must be replaced. - ‣ CIP must be performed after installation. In the case of weld-in connections, exercise the necessary degree of care when performing the welding work on the process side: 1. Use suitable welding material. 2. Flush-weld or weld with welding radius ≥ 3.2 mm (0.13 in). 3. Avoid crevices, folds or gaps. 4. Ensure the surface is honed and mechanically polished, Ra ≤ 0.76 µm (30 µin). Endress+Hauser 13 iTHERM CompactLine TM311 Pay attention to the following when installing the thermometer to ensure that the cleanability is not affected: 1. The installed sensor is suitable for CIP (cleaning in place). Cleaning is performed together with the pipe or tank. In the case of internal tank fixtures using process connection nozzles, it is important to ensure that the cleaning assembly sprays this area directly so that it is cleaned properly. 2. The Varivent® connections enable flush-mounted installation. ## Environment ||Environment|| |---|---|---| |Ambient temperature range|Ta|–40 to +85 °C (–40 to +185 °F)| |||| |Storage temperature||| ||Ts|–40 to +85 °C (–40 to +185 °F)| |||| |Operating altitude|Up to 2 000 m (6 600 ft) above sea level|| |Climate class|In accordance with IEC/EN 60654-1, climate class Dx, class 4K4H|| |Degree of protection|As per IEC/EN 60529 IP69<br>Depends on the degree of protection of the connection cable → 36|| |Shock and vibration<br>resistance|The thermometer meets the requirements of IEC 60751, which specifies shock and vibration<br>resistance of 3 g in the 10 to 500 Hz range.|| |Electromagnetic<br>compatibility (EMC)|EMC in accordance with all the relevant requirements of the IEC/EN 61326 series and NAMUR<br>Recommendation EMC (NE21).
