Temperature switch

The pressure or temperature to be controlled is applied to a sensor (manometric, tube, bellows, bulb). Whenever there is a change of pressure or temperature, the sensor is distorted and acts on a force balance connected to a microswitch. Opposite this sensitive element, an adjustable spring enables the working point to be adjusted : whenever the pressure on the sensor is sufficient to counter the spring pressure, the force balance changes position. Adding a second adjustable spring permits greater or lesser increase of the hysteresis (dead-band) or to act on dislocation between the two contacts if the instruments is thus equipped.

Pressure switch products come standard with a diaphragm-sealed piston or piston actuator for long service life. The stainless steel body is epoxy sealed to protect the precision, snap-acting switch element from extremely harsh environments. An optional sealed switch element improves reliability in harsh or corrosive environments and provides superior contact protection in applications where equipment is washed down or is subject to frequent changes in temperature. vacuostat choices include brass or stainless steel, factory set or field adjustable and many standard process and electrical connections.
