Hubbell Industrial Controls 69HA3 15-60# Pressuresw 7-15#Diff

A pressure switch intended for industrial use, the Hubbell Industrial Controls 69HA3 is used in HVAC equipment. It monitors differential pressure in addition to pressure, serving as a dual-purpose safety precaution. It has a set point that may be adjusted between 15 and 60 pounds per square inch, and when the pressure goes above the predetermined threshold, an electrical circuit is triggered. Additionally, by turning on the circuit when the difference between two pressure points goes beyond an acceptable range, the differential pressure setting of 7 to 15 psi guarantees appropriate airflow or fluid flow inside the system. This double feature protects against overpressure and unbalanced flow, averting equipment damage and even system failures.
