01.20 тип ТППТ, ТПРТ

Thermocouples are designed for temperature measurement in liquid and gaseous non-corrosive media, and also corrosive media that do not damage protective cover material.
Thermocouple TCS, TCR (TCB) 01.20 is equipped with double thermowell made of aluminium-oxide ceramics, which has partial outer reinforcement with steel tube 12Cr18Ni10T. Temperature in transition zone between ceramic and metal thermowell parts should not exceed 800C under operating conditions.
For fitting length 500 mm thermowell ceramic part (C) should be 250 mm long, for other fitting length thermowell ceramic part length should be in the range of 400–1250 mm. Length K should be clearly specified in order.
Ceramic part length should be selected depending on operating conditions, and taking into account, that at horizontal thermocouple operating position ceramic thermowell can be bent under high temperature.
At customer's request the thermocouple can be equipped with single thermowell made of gas-tight aluminium-oxide ceramics.
TCS, TCR (TCB) 01.20 thermocouple design with double ceramic thermowell is registered by the State register of utility models of the Russian Federation, utility model certificate No. 11392 issued by the Russian Patent Agency (Rospatent).
Movable fitting UNKJ 031, UNKJ 041 or movable mounting flange UNKJ 030 are recommended for thermocouple installation at site (see section 11)/

For measuring circuit connection thermocouples can be equipped with thermocouple adapter ATPP
