Solid-state pressure switch F-5500 series

mechanicaldifferentialfor air

This pressure switch uses a Hall Effect Sensor to determine the mechanical movement of the diaphragm. There are no electrical contacts in the switch to wear or fail. This switch requires an AMP 102241-1 connector and external (not provided) circuitry to function. Please see VX Series installation instructions for more information. Pressure switches apply signal pressure to a diaphragm that is opposed by a spring force. When then pressure signal force is greater than the spring force it reaches its set-point (also called “On” pressure), the internal mechanism moves and changes the electrical state. When the switch trips, the normally open circuit closes and the normally closed circuit opens. The switch will remain in this state until the pressure signal drops below its reset point (also called “Off” pressure). The difference between the “On” pressure and the “Off” pressure is defined as the Differential or Hysteresis of the switch. This is an important characteristic for applications such as pressure switch-controlled compressor systems. For instance, the consumption and capacity of the system along with the differential of the switch will determine how often the compressor runs. Factory preset options are available. Please contact your salesperson or distributor for specifications and a custom part number. Adjustments can be made to the switch by removing the round cover and turning the flat head screw. Clockwise adjustments will raise the Set point. Counter clockwise adjustments will lower the setpoint (on pressure). Adjusting preset switches is not recommended. Do not back out the flat head screw above flush with the body.
