The sleeves represent a fitting of steel 20x13 and a welded tube and a plug of steel 12Х18Н10Т.
The article ensures temperature measurment ranging from - 50°C to + 180°C with maximum operating pressure of process medium 1,6 MPa for general designs (2,5 MPa for reinforced designs), with no impairment of the thermal element accuracy class.
The product is intended for operation as part of a resistive temperature transducer. It's applied to protect a sensor from direct contact with the medium subject to mea-suring and to mount the thermal element to a pipeline.
