HK Instruments DPT-R8 Series Installation Instructions

INTRODUCTION
Thank you for choosing an HK Instruments DPT Series Differential
Pressure Transducer. The DPT Series is intended for use in commercial
environments. It is designed with four unit selections (inWC, mmWC, Pa,
mbar) and eight eld selectable measumerement ranges (Unidirectional
and Bi-directional) to meet your job measurement requirements. The
DPT-R8 Series Differential Pressure Transducers is comprised of the
DPT1-R8 with ranges from 0.1 to 1.0 inWC, the DPT10-R8 with ranges
from 0.5 to 10.0 inWC, and the DPT30-R8 with ranges 10.0 to 30.0 inWC.
All DPT-R8 Series Differential Pressure Transducers are available with
display, and NIST standard calibration certi cates.
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 clean rooms
