Features:
• PB Switch Unit Single-Stage Fixed Deadband units have an adjustable set point and a non-adjustable automatic reset point
• P-Series watertight switch enclosures are epoxy-painted, zinc coated steel with a 1/2” conduit hub in the side of the lower housing for electrical entry
• When pressure is applied to the transducer it is converted into movement of the piston. This piston movement is then used to control the operation of the electrical snap-action switch in the switch unit.
• The temperature transducer works on the vapor principle where the internal pressure within the system is generated by the vapor pressure of a chemical within a sealed system
• The temperature sensed by the bulb is related uniquely to an internal pressure within the system
• The pressure acts on a diaphragm/piston to create the force output from the transducer into the switch unit
