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

In order to guarantee sufficient terminal voltage, a maximum load resistance RL (including line
resistance) must not be exceeded depending on the supply voltage UB of the supply unit.
1) 100 mA can be guaranteed over the entire temperature range for the switch output 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" switch output.
2) Larger currents are supported, thus deviating from the IO-Link standard.
