The enterprise was established in 2003 with assistance of Obninsk Center
of Science and Technologies. The main business line of the enterprise is
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-
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
About the Company
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.
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
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-
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,
