SHEATH MATERIAL
SUS304
SUS316 - Excellent pitting corrosion resistance & crevice corrosion resistance, widely used in the chemical industry.
Inconel600 - Heat & corrosion resistant steel with strong stress and corrosion resistance, widely used in various heating components and petrochemical industry.
MOUNTING & FIXING
A variety of mounting options including fixed or movable flange, fixed or movable thread, or without mounting fixing.
JUNCTION STYLES & DETAILS
Grounded
1. Good heat transfer from the outside to the thermocouple junction
2. Rapid response
3. No suitable in case with electrical noise
Ungrounded
1. Response time is slower than the grounded style
2. Long service life
3. Resistance to electrical noise
Exposed
1. Rapid response
2. Suitable to measure the temperature of gas
3. Poor mechanical strength in contact with other measuring structures
