DPS-984A
Differential pressure transmitter for HVAC and cleanroom applications with Autozero for continuous accurate measurements
The differential pressure transmitters of the 984 series are used to measure differential pressure, overpressure and vacuum.
They provide up to 2 pressure ranges and 2 output signals which are easily selectable by jumper.
Due to the automatic zero calibration is a potential drift automatically corrected.
Applications
Possible usage areas are:
Building automation and air conditioning systems
Overpressure measurement in clean rooms and laboratories.
Measurement of constant pressure in VAV applications.
Dynamic filter and ventilator monitoring
