- Pressure transmitter for liquid and gaseous media
- Precise analogue output (4...20 mA)
- Stainless steel thick-film measuring cell - welded gasket-free
- Can be used for high media temperatures up to 135°C
- Suitable for refrigerants - also ammonia
DescriptionThe electronic pressure transmitter AP028 was designed for industrial use with liquids and gases and has a measuring range of 0 ... 250 bar. The device has an analog output (4...20 mA), a G1/4 A process connection (according to DIN EN ISO 1179-2) and an M12 plug connection. The pressure transmitter has a compact design with IP67 protection, excellent measuring accuracy and very high operational reliability.
Suited for group 2 fluids according to the Pressure Equipment Directive (PED).
The pressure transmitter is based on thick-film technology, in which the pressure measuring cell is welded to the pressure transducer without seals. In addition to the high burst resistance required in various applications, these pressure transmitters are also suitable for use with all refrigerants including ammonia. Other applications include hydraulic applications or applications with inert gases.
Note: When used with an analogue output use exclusively sensor cables without LED.
