Introduction

Principle & Structure

Using the principle of bimetal, when the temperature reaches the set value, one end of the bimetallic sheet wound into a circular curved shape is thermally expanded to trigger the built-in mechanical device, and the switch acts.

Features

The part in contact with the medium is made of stainless steel, with high temperature resistance

Mechanical trigger to prevent electromagnetic interference

Very high repeatability with stable action points

Simple installation, a variety of connection options are available

Normally open or normally closed optional

application

Suitable for measuring water, oil and gas media

TK11 temperature switch can meet different requirements for temperature control in hydraulic, lubrication and transmission systems, and is used to detect whether the temperature exceeds the maximum or minimum limit.
