Temperature switches

For each application the right temperature switch

Temperature switches are used in a variety of industrial and technical processes. If a preset temperature is reached, then the temperature switch opens or closes a corresponding switch contact. Depending on the requirements, mechanical or electronic switches can be used. In WIKA's broad product range, you will find the right temperature switch for every application.

What are the advantages and disadvantages of 2-wire, 3-wire, and 4-wire RTDs?

The more wires a measuring resistor (e.g., Pt100) has, the more accurate – and more expensive – it is.

• A basic 2-wire connection creates an electrical resistance for temperature sensing, but the circuit adds the resistance of the lead wires to the ...

What is the repeatability with mechanical pressure or temperature switches?

The repeatability is one of the most important performance characteristics for pressure or temperature switches. It describes the maximum deviation between the switch points when repeatedly approaching the same pressure or temperature value. This v ...
