Bi-metal dial thermometers

Our local reading industrial thermometers operate on the bi-metal coil principle. The bi-metal coil is enclosed in a stainless steel immersion tube and exposed to the temperature of the measured medium. The coil twist varies with rising or falling temperature. This twist acts directly on the pointer via an axle. The resulting pointer deflection is therefore proportional to the change in temperature.

All models of SIKA bi-metal dial thermometers conform to EN 13190 Class 1.

SIKA precision bimetal dial thermometers are the tried and tested solution for local temperature measurement of fluids and gases in the industrial sector. They are ideal for installation in pipelines, containers, machines and plants and do not require any external power. Based on the high protection class (IP65) and the measurement principle, which makes them insensitive to ambient temperature fluctuations, we recommend these versions for outdoor use also.


Type 621 to 681 dial thermometers are local thermometers with a crimped-on ring case. Cases, immersion tubes and connections are made of stainless steel. All devices comply with EN 13190 and meet the class 1 requirements.

The devices are available in the nominal sizes from 63 to 160 mm. Through the crimped case, the thermometers are permanently sealed (IP65) and they are ideal for case fillings with silicon oil (optional).

We supply many different display ranges with measurement spans from 60 to 600 K. On the connection side, our standard range includes three different designs, six different connection types, various connecting threads along with numerous immersion tube lengths and diameters. When combined with each other, the variants facilitate perfect solutions for nearly any application.

In addition to our standard range we also fabricate special versions based on customer specifications. A great number of options are possible. Please get in touch with us! Promo toyota cilegon toyota madiun promo toyota serang Halina
