Product catalog summary

Specifications:

Potentiometers for zero and span adjustment.
Accuracy: 0.4%.
Measuring ranges: 0 to 1, 0 to 2.5, 0 to 6, 0 to 10, 0 to 16, 0 to 25 bar.
Output signal: 4 to 20 mA or 0 to 10 V.
Process connection: 1/2”NPTM, G1/2".

Application:

The pressure transmitter AS is suitable for measuring the pressure of gases, vapors, and liquids. It is applicable in water supply systems and heat engineering.

Construction:

The device features a piezoresistant silicon sensor separated from the medium by a diaphragm and manometric liquid. The electronics are housed in a casing with IP65 protection. Electrical connection is via DIN EN 175301-803 connector.

Installation:

The transmitter is lightweight and can be easily installed. For steam or hot media, a siphon or impulse line is recommended. A needle valve upstream simplifies installation and replacement.
