Absolute pressure transmitter

This absolute pressure transmitter accurately measures atmospheric air pressure, making it ideal for use in ventilation and air conditioning technology or in weather stations. A temperature-compensated measuring element guarantees high reliability and accuracy. Its greatest advantage is maximum flexibility: DIP switches allow you to select the output signal (0-10V/4-20mA) and one of four measuring ranges directly on site, which simplifies integration into any control system and reduces inventory.

Pressure transmitter - Important assembly instructions
To ensure a long service life, install the transmitter with the cable gland facing downwards or to the side. If installing to the side, lay the cable in a drip loop to prevent water from entering. Avoid installing with the cable gland facing upwards, as this will compromise the seal.
