INSTRUCTIONS

DIFFERENTIAL PRESSURE TRANSMITTERS 

DPT-2W Series

• 

READ THESE INSTRUCTIONS CAREFULLY BEFORE 
ATTEMPTING TO INSTALL, OPERATE OR SERVICE THIS DEVICE.

•  Failure to observe safety information and comply with 

instructions can result in 

PERSONAL INJURY, DEATH AND/OR 

PROPERTY DAMAGE

.

•  To avoid electrical shock or damage to equipment, disconnect 

power before installing or servicing and use only wiring with 
insulation rated for full device operating voltage.

•  To avoid potential fire and/or explosion do not use in potentially 

flammable or explosive atmospheres.

•  Retain these instructions for future reference.
•  This product, when installed, will be part of an engineered 

system whose specifications and performance characteristics 
are not designed or controlled by HK Instruments. Review 
applications and national and local codes to assure that the 
installation will be functional and safe. Use only experienced and 
knowledgeable technicians to install this device.

SPECIFICATIONS

Thank you for choosing an HK Instruments DPT series differential 
pressure transmitter. The DPT series is intended for use in commer

-

cial  environments.  The  DPT-2W  series  differential  pressure  trans

-

mitter provides a 4–20 mA loop output.

All  DPT-2W  series  differential  pressure  transmitters  are  available 
with display and/or flow linear output.

DPT-2W 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
