The housings of this product line are equipped with U-bolts, providing easy and secure panel installa-tion in areas that are subjected to vibration.

The switching point of the micro switch, which is installed as a two-way switch, can be varied over the entire temperature range. Devices with a fixed temperature value or one fixed switch and one ad-justable switch can be supplied on request. A pro-tective plastic cap for covering and sealing the connections is also available.

Measurements are recorded by the liquid-filled measuring system, which consists of a tempera-ture sensor, a capillary tube and a Bourdon spring. These three components combine to form a closed tube system.
The internal pressure in this system changes de-pending on the temperature, which causes the pointer axle connected to the spring to rotate and display the temperature value on the scale.

Temperatures of between -40°C and +400°C are rapidly and accurately indicated by the closed sys-tem.

The capillary tube, which is between 500 mm and 10000 mm in length, allows measurements to be taken at any point using a mechanical remote display.
