PRESSURE

DIFFERENTIAL PRESSURE TRANSMITTERS
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, tt
including: Pa, kPa, mbar, inchWC, mmWC, psi.
• 8 field selectable measurement ranges, unidirectional or
bi-directional, selectable via jumper, (see Model Summary).
• Proportional output options including: voltage (0–10 V) and tt
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
The versatility of the DPT-R8 series differential pressure transmitters
ensures that the right product for your application is available.
