USER-FRIENDLY MEASURING DEVICES differential pressure transmitters dpt-r8 series Field adjustable, multi-range differential pressure transmitters for air 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 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) • DPT-2W series differential pressure transmitters with 4-20 mA 2-wire configuration • DPT-MOD series differential pressure transmitters with Modbus configuration • DPI series electronic differential pressure switches • PS series mechanical differential pressure switches • DPT-Flow series air flow transmitters Copyright HK Instruments 2018 www.hkinstruments.fi Datasheet Version
