SPECIFICATIONS
Thank you for choosing an HK Instruments PS series differential
pressure switch. The PS series is intended for use in commercial en
-
vironments. It is designed with field selectable setpoint adjustment
to meet your application requirements.
The PS series differential pressure switches is comprised of PS300
with range from 30...300 Pa, PS500 with range from 30...500
Pa, PS600 with range from 40...600 Pa, PS1500 with range from
100...1500 Pa and PS4500 with range from 500...4500 Pa.
PS series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• pressure and flow monitoring
• valve and damper monitoring
