pressure switches

pressure switches

Pressure switches operate an electrical contact when a certain fluid pressure has been reached. When the pressure reaches the set-point or reset-point the pressure switch opens or closes the contacts to prevent under- or overpressure of a system.

Tameson provides two main types of pressure switches: electromechanical and mechanical (solid state). The mechanical pressure switches are available with three different types of contacts: normally open (NO), normally closed (NC) and changeover (Single Pole, Double Throw or SPDT). The electronic pressure switches have a digital display to set up the switching function. In a pressure switch, a diaphragm or a piston opens or closes a circuit when the pressure reaches the set-point or drops to a reset-point. In the mechanical pressure switch, the setting pressure is typically adjusted with a hex key or turning knob. In the electrical pressure switch the set-point and reset-point can be adjusted with a digital display. The difference between the switch point and the reset point is hysteresis. Hysteresis for mechanical pressure switches is usually determined by the manufacturer, the hysteresis for electronic pressure switches is usually configurable.

Our pressure switches are available with different types of housing material and seal. The media and temperature range are important to choose the material. Check our chemical resistance table to choose the correct material.

Other important factors to select a pressure switch are: maximum overpressure, degree of ingress protection, ATEX approvals, reproducibility, resistance to vibration and shock, process connections, switch capacity and the type of electrical connection.
