Differential Pressure Transmitter 984 from -500 Pa to 1 bar
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 jumper or rotary selector switch.
For an optimum adaptation to the application, the transmitter can be switched between various pressure ranges. The factory setting is the most sensitive range. For the series 984M and 984A the less sensitive second range will be selected by simply removing a jumper. For the series 984Q the available eight ranges can be selected by a rotary selector switch.
Applications
- 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
