Description

Differential Pressure Transmitter 985A with Autozero function and 985Q with eight pressure ranges are as variations avaiable. General description The differential pressure transmitters of the 985 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-combustible and non-aggressive media. 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 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 985M and 985A the less sensitive second range will be selected by simply removing a jumper. For the series 985Q the available eight ranges can be selected by a rotary selector switch.
