Barksdale C9622-2 Dual Band Pressure Switch 125-1500 PSI 10-140 PSI

The Barksdale C9622-2 pressure switch is specifically developed for use in HVAC equipment. The pressure range of this two-wire switch is adjustable from 125 to 1500 pounds per square inch (psi). A headband that can be adjusted to change the pressure at which the switch goes on and off is another characteristic of this device. This allows the exact timing of the switch's activation and deactivation. Current can flow across the circuit when the switch contacts close, indicating that the HVAC system's pressure has reached the setpoint. This can be used to initiate a variety of operations, including turning on fans or pumps, turning off equipment, and setting off alarms.
