DIFFERENTIAL PRESSURE TRANSMITTERS DPT250-R8-AZ-D-S
DPT-R8 Series
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 measuring units, field selectable via jumper,
including: Pa, kPa, mbar, inchWC, mmWC, psi.
• 8 field selectable measurement ranges, unidirectional or bidirectional,
selectable via jumper, (see Model Summary).
• Proportional output options including: voltage (0–10 V) and
current (4–20 mA).
DPT-R8 series device options offer:
• AZ (autozero) function for automatic zero point calibration,
eliminating the need for periodic manual autozeroing to ensure
long term accuracy
• Backlit display
• Field adjustable span point calibration (i.e. gain)
Performance
Accuracy (from applied pressure):
Models 250 and 2500:
Pressure < 125 Pa = 1 % + ±2 Pa
Pressure > 125 Pa = 1 % + ±1 Pa
Model 7000:
Pressure < 125 Pa = 1.5 % + ±2 Pa
Pressure > 125 Pa = 1.5 % + ±1 Pa
(including: general accuracy, temperature drift, linearity,
hysteresis, long term stability, and repetition error)
Thermal effects:
Temperature compensated across the full spectrum of
capability
