HK Instruments DPT-R8 Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments DPT series differential
pressure transmitter. The DPT series is intended for use in com-
mercial environments. It is designed with six unit selections (Pa,
kPa, mbar, inchWC, mmWC, psi) and eight field selectable meas-
urement ranges (unidirectional and bi-directional) to meet your job
measurement requirements. The DPT-R8 series is comprised of
the DPT250-R8 with ranges from 25 Pa to 250 Pa, the DPT2500-
R8 with ranges from 100 Pa to 2500 Pa, and the DPT7000-R8
with ranges from 1000 Pa to 7000 Pa.
All DPT-R8 series differential pressure transmitters are available
with display and autozero calibration.
APPLICATIONS
DPT-R8 series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• pressure and flow monitoring
SPECIFICATIONS
• valve and damper control
• pressure monitoring in cleanrooms
