PS 27

Compact differential pressure transmitter for positive or negative differential pressures in basic applications

Special features

• ± measurement ranges and asymmetric measurement ranges
  
• Either with 1 fixed measurement range or toggling between 4 different measurement ranges (can be selected via DIP switches, optional)
  
• Suitable for top-hat rail mountingand wall surface installation
• Selectable output signal 0/2 .. 10 V, 0/4 .. 20 mA or 0 .. 5 V
  
• Can be calibrated
  
• Zero-point calibration via an external signal reduces maintenance costs
• The adjustable limit switch permits the connection of, e.g. ventilators or signalling devices, and saves additional wiring (optional)
• Electrical connection: With standard M16 cable gland, optional 4-pin M12 plug with A-coding

This compact differential pressure transmitter is particularly suited to filter and pressure monitoring applications in the heating, air-conditioning and ventilation industries. 

Options

• The instrument is available with an factory calibration certificate or calibration certificate according to DKD-R 6-1.
• An optional display allows measurement values to be read directly on-site in Pa or kPa. 
  
• An optional time constant (up to 4s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions.
• To reduce wiring costs, the instrument is also available in a version with two-wire technology (optional).
  
• Pressure ports also as push-in fittings on request
