Flexible-use differential pressure transmitters for building technology

The sensor manufacturer Setra Systems is one of the leading producers of capacitive differential pressure transmitters in the HVAC sector. The MRX family offers a series of models that are almost unmatched in terms of versatility and flexibility.

The models feature up to 8 switchable, uni- and bidirectional pressure ranges between 25 and 7,500 Pa. The output signal can be set to 0 ... 5 V, 0 ... 10 V, or 4 ... 20 mA. The pressure transmitters offer an accuracy of 1% FS, with the MRC model even achieving 0.5% FS. The selection of the measurement range and output signals is made via switch or jumper. The measured pressure is additionally displayed on a 4-digit LCD in freely selectable units. Installation can be surface-mounted or mounted in a control cabinet on a DIN rail. After installation, a simple zero point calibration via pressure button is guaranteed.

Due to its high flexibility, this series of models is used in the HVAC sector, building technology, laboratory and cleanroom monitoring, as well as in other various applications where the reliable measurement of very small pressures is essential.
