DPT-R8 series differential pressure transmitters are engineered for building automation in the HVAC/R industry.(-AZ Auto zero calibration)
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).
• Measuring ranges
-150...+150 / -100...+100 / -50...+50 / -25...+25 / 0...25 / 0...50 / 0...100 / 0...250 Pa
