  • Introduction
  • Specifications
SBW series explosion-proof and intrinsically safe temperature transmitter with Thermocouple/ Thermal resistor is an on-site installation temperature transmission unit of DDZ-S Series instrument. It combines transmitter with thermocouple (Thermal resistor) as one unit to measure temperature of liquid, vapor and within -200~800℃ in production. It will convert temperature into 4~20mADC unified output signal which has direct ratio with thermocouple temperature or output signal then send to display, record devices or computers. The explosion-proof performance of temperature transmitter is designed and manufactured according to "explosive environment, explosion-proof electrical equipment" (GB3836) which promulgated by our nation. Thermoelectric properties are in line with international IEC standards and tested by National Safety Supervision Station. It is the ideal transmission temperature sensor in explosive environment. The explosion-proof certification number is GYB 93265、93266、97336、97337.
As a new-type of temperature transmitter, it is widely used in metallurgy, petroleum, chemical, electric power, light industry, textiles, food, national defense and scientific research sectors.
