Thermostat and pressostat switch applications

Today, there exists a broad range of sensors for temperature and pressure control in process automation applications. In a large range of situations, however, the simplest solution is a pressure or temperature switch that activates power directly, without the need for an interconnected controller or electronics circuit. This simple arrangement proves to be not only easy to use, but also a cost effective solution.

While pressure or temperature switches deliver the advantage of simplicity, good resistance to electromagnetic disturbencies and temperature, they have some disadvantages related to the mechanical design. In its latest switch design, Microprecision addressed two of these limitations.
