Genuine thermoelements with metal tubes are specially designed for use at increased temperatures, e.g. in various industrial furnaces, for temperatures up to 1250°C.

Electrical connection is made via a terminal block or a transmitter.

Basic parts of thermoelement are as follows:

• – connection head,
• – external protection tube,
• – measuring insert,
• – process connection.

Connection head of thermoelement can be of various dimensions and shapes and is defined through the configurator.

External ceramic tube of thermoelement is made of material selected to suit the process conditions and is directly immersed in the medium in which the temperature is measured.

Measuring insert can be in classic and mantel design with different types of thermocouples (J, K, N, T, S) that are defined via the configurator.

We recommend the mantel design, which has a number of advantages:

• – there is no contamination and oxidation of the hot end of the thermocouple, because it is in highly compressed magnesium oxide, without the presence of oxygen,
• – faster response,
• – great resistance to vibrations,
• – higher reliability in operation,
• – longer service life.

The only advantage of the classic measuring insert is the lower price.

Process connection is achieved using:

• flange, according to DIN 43734,
• movable connection (compression fitting)

Flange and movable connection (compression fitting) can be moved along the longitudinal axis of thermoelement, which regulates the installation length.

Technical characteristics

Basic technical characteristics are specified in the configurator.

By filling in the configurator, an order code is generated, which defines the product.

Use
– blast furnaces,
– annealing and heat treatment furnaces,
– boilers on fuel oil, natural gas, biomass, electricity,
– cement industry,
– brick factories.
