## Function and system design 

## Measuring principle - process pressure measurement 

Devices with metallic process isolating diaphragm 

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated. 

## Advantages: 

- Can be used for high process pressures 

- Fully welded sensor 

- Slim, flush-mounted process connections available

The maximum load resistance depends on the terminal voltage and is calculated according to the following formula: 

> 1) 100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be guaranteed over the entire temperature range for the "1 x PNP" current output. 

> 2) Larger currents are supported, thus deviating from the IO-Link standard.

## Installation 

## Installation conditions 

- Moisture must not penetrate the housing when mounting the device, establishing the electrical connection and during operation. 

- Point the cable and connector downwards where possible to prevent moisture from entering (e.g. rain or condensation water). 

Influence of the installation position 

Any orientation is possible. However, the orientation may cause a zero point shift i.e. the measured value does not show zero when the vessel is empty or partially full. 

|**C**<br>**A**<br>**B**|**C**<br>**A**<br>**B**|**C**<br>**A**<br>**B**|**C**<br>**A**<br>**B**|

## Level measurement 

- Always install the device below the lowest measuring point. 

- Do not install the device at the following positions: – In the filling curtain 

- In the tank outlet 

- in the suction area of a pump 

- Or at a point in the tank which could be affected by pressure pulses from the agitator. 

- A functional test can be carried out more easily if you mount the device downstream from a shutoff device.

For further information please contact your local Endress+Hauser Sales Center. 

## L[[WARNING]] 

> Pressure specifications L[[WARNING]] The maximum pressure for the measuring device depends on the lowest-rated element with regard to pressure. 

- ‣ For pressure specifications, see the "Measuring range" section and the "Mechanical construction" section. 

- ‣ The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring device. 

- ‣ MWP (maximum working pressure): The MWP (maximum working pressure) is specified on the nameplate. This value is based on a reference temperature of +20 °C (+68 °F) and may be applied to the device for an unlimited period of time. Observe the temperature dependency of the MWP. 

- ‣ OPL (over pressure limit): The test pressure corresponds to the over pressure limit of the sensor and may only be applied temporarily to ensure that the measurement is within the specifications and no permanent damage develops. In the case of sensor range and process connections where the over pressure limit (OPL) of the process connection is smaller than the nominal value of the sensor, the device is set at the factory, at the very maximum, to the OPL value of the process connection. If you want to use the entire sensor range, select a process connection with a higher OPL value.
