USER-FRIENDLY MEASURING DEVICES differential pressure switches dpi series Electronic differential pressure switch(es) and transmitter The DPI series electronic pressure measuring devices are engineered for building automation in the 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: o Open on rise or fall in pressure o Hysteresis of set-point • Measurement units (Pa, kPa, mmWC, inWC, mbar) • Measurement ranges (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 pressure similar products applications • PS series mechanical differential pressure switches • DPT-R8 series 8-range differential pressure transmitters • DPT-MOD series differential pressure transmitters with Modbus configuration 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 model summary Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Versio
