DPT-R8

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 fiel

Technical specifications

 

Accuracy (from applied pressure):

Models 250 and 2500: 

Pressure < 125 Pa = 1 % + ±1 Pa 

Pressure > 125 Pa = 1 % + ±2 Pa

Model 7000: 

Pressure < 125 Pa = 1.5 % + ±1 Pa 

Pressure > 125 Pa = 1.5 % + ±2 Pa

(including: general accuracy, temperature drift, linearity, 

hysteresis, long term stability, and repetition error)
