A:The product says all:
The packs thermocouple,hot electric resistance to be usually more applied than assemble type thermocouple,hot electric resistance to install difficult place, since can be a temperature to spread the feeling machine to use directly, be the feeling component of the assemble type thermocouple,hot electric resistance again, have special use value.At to the stalk tile, bearings, the electrical engineering turns son etc. is narrow, the temperature that curves part measures and controls in exertive special function.
Two:Product characteristics
1:Measure accuracy high, respond intelligent.
2:The heat responds to speed quick(reach to a 0.5 Ss most quickly), the stainless steel coat, a time pulls to stir to take shape.
3:Bear corrosion, the service life is long.
4:Take care of path thin have a tenacity, easily bent, bear vibration, ability at narrow,the turns and twists position install.
5:Be When the diagraph component of the assemble type thermocouple,hot electric resistance use, can rise to replace fast, double the layer protection function.

Three:Technique parameter
