Differential pressure transmitter 984
General description
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.
Applications
Monitoring of gaseous, non-aggressive media. Possible usage areas are:
l Building automation and air conditioning systems
l Overpressure measurement in clean rooms and laboratories
l Measurement of constant pressure in VAV applications
l Dynamic filter and ventilator monitoring
Configurable pressure range
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.
Output signal selection
The output signal of the 3-wire version is configurable.
The factory setting is for a 0 ...10 Volt output signal which can be changed to a 4 ... 20 mA signal by removing a jumper.
The series 984M is even available in a 2-wire version with 4 ... 20 mA output signal.
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.
Easy offset calibration
The output signal of the 984M series can be calibrated to zero by pressing the M push-bottun in a pressureless state of the transmitter.
The series 984A and 984Q perform an automated zero offset compensation. Here any drift of the zero-point is automatically corrected in regular intervals. No re-calibration is needed which reduces monitoring and maintenance efforts.
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 a differential pressure.
Switching output
(optional, not available with 2-wire version)
To give a switch signal at an user defined pressure level the transmitter has an adjustable transistor switching output with a maximum switching capacity of 30 Vdc/100 mA.
Display
(optional, not available with 2-wire version)
In addition to the analogue output signal the pressure value can be read out on a red LED-display in Pascal or other pressure units.
Measuring method
Piezoresistive pressure transducer
Mounting position
Can be mounted in any position. The zero offset calibration eliminates any possible position error.
