Differential pressure switches with excellent long-term stability.

An air pressure switch is a mechanical device that depends on pressure for controlling the electric air compressor’s operation process. The air pressure circuit mechanism of the device sends power to the motor to function. The air compressors’ pressure switch has a pressure switch relief valve. This valve helps the machine for easier

Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.

NDPS 2000 Differential Pressure Switch is designed for use in air or gases where proof of airflow is needed for proper system operation.

Differential Pressure Switch. Normally used as a DP switch with pressures from two different sources (one may be atmospheric for the pressure switch) of a particular process that are connected to the two inputs. If there is an air flow failure, the differential pressure switch f4 must cut off the control voltage of the electric heating coil

Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures.

A differential pressure switch is a device that monitors and controls gaseous pressures to actuate an electric circuit-connected switch at pre-selected pressure points. We call the pre-selected pressures high pressure and low pressure, two high or two low pressures, one of each, or high and ambient or low and ambient pressure.

For Use With: Air. Connection Material: Aluminum. Connection: NPT Female. Switching Current: 15A. Switching Voltage: 120V AC/240V AC/480V AC. Often used with ovens, dryers, and HVAC systems, these switches detect small differences in pressure. When the differential pressure exceeds your setpoint, the switch is activated.

Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.

The 930 range of low differential pressure switches are used in air conditioning systems to measure fan status and filter conditions 

LF31 switches offer pressure, vacuum, and differential models capable of sensing very low setpoints and switching current up to 5A resistive,2.5A inductive.

The differential pressure switch follows the pressure between the two places. If the pressure reaches a particular point, then the internal diaphragm in the switch will make contact after deflecting. This contact will either make or break a circuit.

In differential adjustment, the cut-in pressure can be increased or decreased on the pressure switch, changing the pressure differential. For example, on a 90 psi (cut-in) to 110 psi (cut-out) range pressure switch, you can change the cut-in to either 80 psi or 100 psi while keeping the cut-out at 110 psi.
