Explosion-proof Thermocouple fixed thread
Normally and display instruments , Recording instruments , Computer and other ancillary uses . Direct measurement of the presence of hydrocarbons and other explosives production site of 0 ℃ ~ 1300 Within ℃ range of liquid , Steam and gas and solid surface temperature .
Explosion-proof thermocouple principle is the use of space , Designed with sufficient strength to junction boxes and other components , All will produce sparks , Arcs and dangerous temperature of the components are sealed in the junction box cavity , When the cavity explosion , Flame and cooling through the joints clearance , So that after the explosion of flame and temperature not pass outside the chamber , Thereby performing explosion .
More proof in the form , Proof performance ;
Compression spring-type temperature sensing element , Good vibration resistance ;
Large measuring range ;
High mechanical strength , Good pressure resistance .
The main technical parameters:
