Description CPS-A

CPS-A is designed for measuring differential pressure in ventilation installations.

The CPS-A pressure sensor has an integrated differential pressure element that is temperature compensated for high accuracy and linearity. The pressure element and the output signal has high resolution which means that the pressure value is presented in increments of max 1 Pa over the entire measurement range (-50 to + 3500 Pa).

Measurement range, output signal (0-10V or 4-20 mA) and required signal damping are set with a DIP switch. The CPS-A is factory set (all DIP switches in ON position) with a measurement range of 0-500 Pa, 0-10V output signal and high signal damping.

The measurement range determines at which measured value the output signal will start and when the maximum output signal will be given.

All settings are listed on a label inside the cover.

The terminal block and enclosure cable port (with a pre-mounted M16 cable gland) are removable for easier installation. The enclosure cover is hinged at the top, has a snap fastener at the bottom and catches to keep the cover in raised position.


CPS-A is wall-mounted with the hose connectors pointing downwards. For more information please refer to the installation instructions.
