Description

DPI

The DPI series electronic pressure measuring devices are engineered for building automation in HVAC/R industry. The most technologically advanced and versatile electronic differential pressure switches on the market, combining up to two relay outputs and 0–10 V output options.

The DPI includes the following field selectable features:

  • Configurable switching point: Open on rise or fall in pressure
    • Hysteresis of setpoint
    • Measurement units (Pa, kPa, mmWC, inWC, mbar)
    • Measurement range (4 ranges per model)
    • Output signal (0−10 V, NO/NC)
    • Span and zero-point calibration

DPI options include:

  • Up to 2 relays, which can be configured separately
  • Autozero calibration

DPI series devices are commonly used in HVAC/R systems for:

  • fan, blower and filter monitoring
  • staircase pressure monitoring and alarm
  • pressure monitoring in cleanrooms
  • boiler pressure monitoring and alarm

Similar products:

  • PS series mechanical differential pressure switches
  • DPT-R8 series 8-range differential pressure transmitters
  • DPT-MOD series differential pressure transmitters with Modbus configuration
