Field adjustable, multi-range differential pressure transmitters for air

DPT-R8 series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market measuring static and differential pressure, with field selectable units, range and output, all in a single device.

DPT-R8 series devices include:
• Multiple measurement units, field selectable via jumper, including: inWC, mmWC, Pa, mbar.
• 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper.
• Proportional output options including: voltage (0–10 V) and current (4–20 mA).

Technical details

Accuracy (from applied pressure):
(models 250 and 2500)		 Pressure < 125 Pa = 1 % + ±2 Pa
Pressure > 125 Pa = 1 % + ±1 Pa
Accuracy (from applied pressure): 
(model 7000)		 Pressure< 125 Pa = 1.5 % + ±2 Pa
Pressure > 125 Pa = 1.5 % + ±1 Pa
Zero point calibration: automatic with autozero element (-AZ) or by pushbutton
Measuring units: Pa, kPa, mbar, inchWC, mmWC, psi
Supply voltage: 24 VDC ±10 % / 24 VAC ±10 %
Power consumption: < 1.0 W (< 1.2 W with output current 20 mA)
Output signals (3-wire): 0…10 VDC, Load R minimum 1 kΩ 
4…20 mA, maximum load 500 Ω
Operating temperature: -10…+50 °C (with autozero calibration -5...+50 °C) -40…+50 °C (-40C model)
Response time: 0.8 / 4 s
Protection standard: IP54
  inWC models: ETL marking, standard IEC61010-1
