Field adjustable, multi-range differential pressure transmitters for air

DPT-R8

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 (see Product Information).
• Proportional output options including: voltage (0–10 V) and current (4–20 mA).
Applications

DPT-R8 series devices are commonly used in HVAC/R systems for:

• fan, blower and filter monitoring
• pressure and flow monitoring
• valve and damper control
• pressure monitoring in cleanrooms
