DPS-984Q
Differential pressure transmitter for HVAC and cleanroom applications
The differential pressure transmitters of the 984 series are used to measure differential pressure, overpressure and vacuum.
They provide up to 8 pressure ranges and 2 output signals which are easily selectable by rotary switch.
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
