Description

The gauge pressure transmitter CRV-809 was developed for measuring of dry, non aggressive gases and compressed air. It can be used for varied HVAC applications.

The basic element of the CRV-809 is a temperature compensated piezoresistive pressure sensor which is able to operate a very long time without any maintenance.
Robust design allows deployment also in laboratories and industrial conditions. The pressure transmitter CRV-809 features good long term stability, linearity and repeatability.
