Field adjustable, multi-range differential pressure transmitters for air
DPT-R8
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).
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
