The differential pressure transmitters of the 984M series are used to measure differential pressure, overpressure, and vacuum. They provide 2 pressure ranges and 2 output signals, which are can be easily selected using a jumper.
Monitoring of gaseous, non-aggressive media. Possible usage areas are:
Building automation, air conditioning systems, and cleanroom monitoring
Valve and flap control
Monitoring of air Filter
Monitoring of air ventilator and blower
Monitoring & control of airflow in ventilation ducts
Configurable pressure range
For optimum adaptation to the pressure application, the transmitter can be switched between two pressure ranges.
The factory setting is the sensitive range 1, which is selected by fitting a jumper. Removing the jumper activates the
non-sensitive range 2.
Configurable response time
The response time of the output signal can be configured using a jumper. If the jumper is in place the response time is slow (factory setting), which is useful for suppressing brief pressure peaks. If the application requires a fast response time the jumper must be removed.
Volume flow measurement (optional)
The shape of the output signal can be switched from linear to square root using a jumper in order to measure the volume flow via differential pressure.
