Temperature Gauges

Temperature gauges operate on the gas-actuated, bimetal or expansion principle. They can measure temperatures between -200 … +700 °C. All instruments are also suitable for operation in thermowells.

Temperature gauges measure the thermal state of a homogeneous substance. The measuring system must be brought as closely together as possible with the body to be measured. The most widely used measuring methods rely on temperature-dependent physical and material characteristics.

JWF has partnered with WIKA in Scotland since 1972 and are responsible for the full sales and technical promotion of WIKA products.

Our range of WIKA temperature gauges:

Bimetal temperature gauge

Bimetal temperature gauge

Bimetal temperature gauges operate with a measuring system in the form of a helical or spiral tube. Bimetal temperature gauges are available with a scale range of -70 ... +600 °C in accuracy classes 1 and 2 in accordance with EN 13190.


Expansion temperature gauge

Expansion temperature gauge

An expansion temperature gauge consists of a temperature sensor, a capillary and a Bourdon tube. The measuring system itself is filled with a liquid. Using capillaries from 500 to 10,000 mm long, measurements can also be taken from remote measuring points. The scale ranges for expansion temperature gauges lie between -40 ... +400 ° C with class 1 and 2 accuracies in accordance with EN 13190.


Gas-actuated temperature gauge

Gas-actuated temperature gauge

With a gas-actuated temperature gauge the stem, the capillary and the Bourdon tube are joined together into one unit. The instrument is filled with inert gas. Gas-actuated temperature gauges are available with scale ranges between -200 ... +700 °C in accuracy class 1.
