Whether it's reliable temperature measurement in steam pipelines at power plants or the exact determination of process temperatures in chemical plants, KROHNE thermometers are as versatile as the requirements and specific applications.

Highly resistant and gas-tight thermocouples in the OPTITEMP series are highly insensitive to rapid temperature changes and boast good stability in reducing atmospheres. This means that the enormous thermal and mechanical loads occurring on a daily basis in many industries pose no problems.

OPTITEMP flue gas thermocouples are used in combustion processes such as those found in the iron and steel industry. They are highly resistant to mechanical abrasion. Similar elements can also be used in ovens.

Thermowells with tapered tips are as much a part of the line as metallic thermowells featuring an additional titanium or tantalum casing used, for example, in the event of high chemical exposure.

Suitable thermometer materials are always selected based on the various process media as regards corrosion and abrasion. Strength calculations when it comes to customer-specific thermowells can always be performed on an individual basis.

Accessories:

1 - Compression fittings, 2 - Weld in connection, 3 - Coatings and covers, 4 - Gas-tight threaded sleeves, sliding flange, 5 - Clamp on connection,
6 - Bayonet connection, 7 - Thermowell in different material, 8 - Slide on flange, 9 - Connectors

Depending on the type, our transmitters feature a variety of diagnostic functions which allow users to address the following problems with a high degree of certainty: low sensor isolation resistance, sensor break, sensor short-circuit, sensor drift.

The measuring principle

Electrical thermometers have just one small, sensitive output signal. Temperature transmitters convert that signal into a standardised current signal, proportional to the temperature, that can be transported over long distances without problem. 2-wire transmitters get the required energy from the loop. Their output current of 4…20 mA corresponds to the measuring signal and is always proportional to the temperature. Resistance thermometers and different types of thermocouples can be connected to the transmitter input. Head-mounted transmitters are built into the connection head of a thermometer. If the ambient temperature is too high, a rail-mounted variant is used for the control cabinet.

With the OPTITEMP series, KROHNE always offers customers more than just temperature measuring devices. Depending on the type, KROHNE transmitters feature a variety of diagnostic functions which allow users to address the following problems with a high degree of certainty.
