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.

Application versatility is a contributing factor to continued pressure transmitter growth despite the fact pressure transmitters are continuously threatened by other technologies for measurement of flow and level. Manufacturers are familiar and are comfortable with the technology and are reluctant to change. Looking for nucleonic density gauge, we show a list of selected aadresses.
