Multi-range differential pressure transmitters with 2-wire configuration DPT-2W series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The DPT-2W measure static and differential pressure and they have a field selectable range. DPT-2W series devices include: • 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper • Pressure measurement in Pa • 4-20 mA 2-wire current loop configuration Technical details Accuracy (from FS): ±1.5 % Long term stability, typical 1 year: ≤ ± 8 Pa; model 2500 Measuring unit: Pa Zero point calibration: by pushbutton Supply voltage: 10…35 VDC Output signal: 4…20 mA Operating temperature: -10…+50 °C Response time: 0.8 / 4 s Protection standard: IP54
