341-347 Dial Thermometer

The SIKA 341 to 347 dial thermometers operate on the expansion principle. The non-toxic gas (primarily nitrogen) in the measuring system expands with rising temperature. This causes an increase in pressure, which deforms the bourdon tube. This deformation is converted into pointer rotation by mechanical components and an instrument mechanism.

The SIKA 341 to 347 dial thermometers operate on the expansion principle. The non-toxic gas (primarily nitrogen) in the measuring system expands with rising temperature. This causes an increase in pressure, which deforms the bourdon tube. This deformation is converted into pointer rotation by mechanical components and an instrument mechanism. The resulting pointer deflection is proportional to the temperature change.

SIKA dial thermometer types 341 to 347 are the tried and tested industrial solution for in situ, local temperature measurement of fluids and gases in the industrial sector. They are ideal for installation in pipelines, containers, machines and plants, have a long service life and do not require any external power.

The 341 to 347 dial thermometers are local thermometers with a crimped-on ring cases. Cases, immersion tubes and connections are made of stainless steel. All devices comply with EN 13190 and meet the class 1 requirements.

The SIKA dial thermometers 341-347 are available in the nominal sizes from 63 to 250 mm. Through the crimped cases, the thermometers are permanently sealed (IP65), and they are ideal for case filings with silicone oil (optional). We recommend this version with case filing for applications that involve vibrations.
