Beck. The differential pressure transmitter for air with IP65

Differential pressure transmitter 985 with IP65 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...
