Description
Product introduction:
Model: WZPK
Name: Explosion-proof Armored Thermal Resistance
Manufacturer: Shanghai Automation Instrumentation Co., Ltd.
Application: WZPK Explosion-proof Armored Thermal Resistance is a temperature sensor, is usually used with display instrument and recording instrument. Directly measuring the production site exist hydrocarbon explosion range of 0 ~ 500 ℃ liquid, steam and gas medium, as well as solid surface temperature. in production field, itt is very dangerous to use normal thermal resistance, and will cause explosion of environment gas easily. So, we must use explosive-proof or intrinsic safety type thermal resistance as temperature sensor in these places. Besides, it has Multiple explosive-proof types, good explosion-proof performance, compression spring type thermal components, good anti-vibration performance, high mechanical strength and good pressure-resistant properties.
