Pressures switches joined our portfolio following the acquisition of HNL Engineering in 2012, a company designing and manufacturing pressure switches and manifolds for over 60 years. The switches are built to last in the most demanding of environments.
A pressure switch actuates a corresponding micro switch contact as soon as a preset pressure is reached. Rototherm pressure switches are used in a variety of demanding industrial and technical processes, such as offshore platforms, nuclear applications, and chemical, pharmaceutical and gas transmission to name a few.

Temperature Sensors
-
A Thermocouple consists of two electrical conductors of dissimilar material connected at one end (the hot junction); the two free ends are connected to the measuring instrument via a reference junction (the cold junction). The connection of these two materials provides an electromotive force (emf) proportional to the temperature being measured.
-
A Resistance Thermometer is a temperature sensor constructed from resistance wire wound into an element. It is used to measure temperature by means of a change in the electrical resistance with a rise or fall in temperature.
