Ideal for applications requiring monitoring of non-corrosive air or gas, with pressure ranges from 10mbar to 200mbar. These transmitters utilize piezoresistive sensors to deliver precise and stable measurements of applied (differential) pressure, boasting excellent repeatability, low hysteresis, and superior temperature stability.
The output signal of the sensor is conditioned to provide a voltage output, linearly proportional to the applied (differential) pressure.
Calibrated at the factory, these transmitters are ready for immediate use.
The transmitters are ready to use as they have been calibrated at the factory.
Common applications include monitoring clean room barometric pressure, controlling filters, measuring flows (using Pitot tubes), operating packing and packaging machines, and regulating ventilation systems.
