High-temperature thermometry

The enterprise was established in 2003 with assistance of Obninsk Center of Science and Technologies. The main business line of the enterprise is high-temperature thermometry.

The enterprise organized the in-house licensed manufacture of thermoelectric temperature converters and protection fittings for extra aggressive environments including acid solutions and alkalis, molten metals and salts. The quality management system was introduced for control of conformity to the requirements of ISO 9001 standard and IQ-net.

The Company is engaged in solution of special problems of thermometry including optimization of technological processes of industrial furnaces on the basis of high-precision temperature monitoring systems that determine the temperature range of a furnace or a product in the real time of the thermal treatment process. It carries out research and development in the field of thermometry under Customers' requirements specifications.

About the Company

Director: Anatoly Aleksandrovich Ulanovsky

The Company's main business line is manufacture of temperature measuring devices for extra aggressive high-temperature environments as well as solution of problems of high-temperature thermometry at a customer's facilities.

Thermoconverters of the basic graduation are manufactured under GOST 6616-94, an interstate standard of CIS countries:

A – tungsten-rhenium 5 % - tungsten-rhenium 20%; К - chromel-alumel; B - platinum-rhodium 30% - platinum-rhodium 6 %; N - nichrosil-nisil; S - platinum platinum-rhodium 10 %; L - chromel-copel.

Thermoconverters may be manufactured both as a standard version and according to a customer's drawings or requirements specifications.

A thermoelectric converter (thermoconverter) is a measuring device that uses a thermocouple as a sensor consisting of two different-type conductors and converts the temperature of an environment (object) under measurement to an electric signal of the thermocouple for subsequent transfer, processing or registration by secondary devices.

Products

Tungsten-rhenium thermoelectric converters of TP-A type

Thermoconverters of TP-А-1 type with thermoelectrodes VR 5/20 operate in the temperature range of 0 to 2200°C (up to 2500°C in a short run) in vacuum or in an inert environment.

For operation in an aggressive environment (oxidizing or reducing) thermoelectrodes are sealed with a protective cover of quartz (up to 1200°C), or leucosapphire (up to 1950°C) filled with an inert gas.

In many cases these thermocouples may replace thermocouples of precious metals.

Thermoconverters of TP-S or TP-IN type with thermoelectrodes of precious metals may be installed in protection fittings of heat-resistant steels, ceramics or platinum-rhodium alloys.

Protection of thermoelectrodes may be enhanced with an internal protective cover of quartz glass, corundum or leucosapphire.

Thermoelectric converters of TP-B and TP-S types based on thermocouples of precious metals

Thermoconverters are intended for temperature measurement in vacuum, on the surface of solid bodies, in loose, liquid and gaseous chemically non-aggressive environments as well as in aggressive environments which do not destroy the material of the protective cover.

Thermoelectric converters of TP-K (N, L) types with thermoelectrodes of base metals

For short-term temperature measurements in molten metals, salts and glass.

The sensitive element of a thermoprobe is a thermocouple protected with a ceramic test tube resistant to multiple thermal shocks.

It is sufficient to immerse the protected hot junction for 30-60 seconds in the melt, and a digital device will display the temperature of the melt.

The thermoprobe is fully self-contained, and the digital device is supplied from three standard batteries of АА size.

Thermoconverters for short-term temperature measurements in molten metals, salts and glass

These are intended for installation of thermoconverters at the site of operation and for extra protection of thermoconverters from mechanical and chemical impacts of the working environment.

Products using a thermocouple and heating cable

Furnace temperature profile monitoring systems

Temperature monitoring systems are self-contained units made according to the latest technology and intended for reception of the exact and full information on the temperature profile of furnaces and temperature distribution in articles moving through heating (roasting) furnaces.

The system with an article moves through the entire heat treatment cycle. At the exit of the furnace, the recorder is removed from the container and connected to a personal computer where the data are unloaded to and analyzed.

The system with radiotelemetry makes it possible to see in the real time what is occurring with a product during the heat treatment process with simultaneous data recording to the recorder.

These systems are widely used for control of processes of heating and heat treatment of metal workpieces and articles , for roasting of ceramics, brick, glass articles; for drying of painted articles, in soldering processes and anywhere where the furnace temperature control up to 1600°C is required.
