Technical Data

General Information

Manufacturer: E+H

Instrument Name: Pressure Transmitter

Model: PMC131-A22F1A2K

Applications

Measuring gauge and absolute pressure of gases, steam, and liquids

Operation and System Design

Measuring Principle: The measured pressure causes a slight deformation on the ceramic diaphragm of the sensor. Electrodes on the ceramic sensor measure the resulting change in capacitance, which is proportional to the pressure.

Modularity: The pressure sensing element can be connected to the transmitter power supply via an optional DIN 43650 A/ISO 4400 plug or cable connector.

Input

Measured Variable: Gauge pressure or absolute pressure

Measuring Range: Max. 40bar (see selection table)

Output

Output Signal: 4?20mA

Load: R(Ω) <= (U-11V)/0.02A

Accuracy

Reference Conditions: According to DIN IEC 770

Response Time: 20ms (T time)

Measurement Deviation (including hysteresis and repeatability): 0.5% FS

Influence of Ambient Temperature on Rated Range: Zero signal change between -20?+85℃ (-4...+185°F), typical: 1.5%;

Span change between -20?+85℃ (-4...+185°F), typical: 0.8%; (0.4bar?40bar), typical: 1.0% (0.1bar)
