The three-wire “-3W” option should be ordered when using with a 3-Wire temperature transmitter or sensor configuration on your building management system or PLC (Programmable Logic Controller). The purpose of the 3rd wire is to compensate for external lead wire resistance that affects the sensor output. ACI recommends the use of 1.02 mm (18 AWG) lead wires to reduce the external lead wire resistance when using a Platinum RTD. The sensors in this series are manufactured using ACI’s proven double encapsulation process to eliminate the effects of moisture upon the sensors and to increase thermal response times using our high quality, thermally conductive epoxy. The immersion sensors “-I” include a welded thermowell but can be ordered without the thermowell “-INW” version. The “-INW” includes a standard ½ in NPS process thread to be used with an optional machined thermowell or an existing thermowell application. Optional NEMA/IP rated weather proof enclosures and NIST Certificates are available as referenced on this product data sheet. ## **Applications** Chilled Water Systems, Hot Water Systems, Boilers, Pumps, Compressors, Chillers, Cooling Towers ## **Warranty** The ACI Platinum Immersion Series is covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, workaci.com. **Disclaimer:** Specification of any thermowell and the materials of construction are the sole responsibility of the designer of the system that incorporates the thermowell. Sole responsibility for ensuring compatibility of the process fluid with the system rests with the end user. ## **Specifications** **Sensor Type:** Platinum RTD **Sensor Curve:** PTC (Positive Temperature Coefficient) **Number Sensing Points:** One **Number Wires** - **A/100-2W-I Series** and **A/1K-2W-I Series:** Two (Non- - Polarity Sensitive) - **A/100-3W-I Series** and **A/1K-3W-I Series:** Three (Polarity Sensitive) **Sensor Output at 0 °C (32 °F)** - **A/100-xW-I Series:** 100 Ω nominal - **A/1K-xW-I Series:** 1000 Ω nominal **Sensor Accuracy 0 °C (32 °F):** ±0.06 % Class A ( **Tolerance Formula:** ± °C = (0.15 °C + (0.002 * |t|)) where |t| is the absolute value of Temperature above or below 0 °C in °C) - **-40 °C (-40 °F):** ± 0.23 °C (± 0.414 °F) - **0 °C (32 °F):** ± 0.15 °C (± 0.27 °F) - **200 °C (392 °F):** ± 0.55°C (± 1.00 °F) **Din Standard:** DIN EN 60751 (IEC 751) **==> picture [216 x 139] intentionally omitted <==** **----- Start of picture text -----**
