  • Introduction
  • Specifications
SBW series temperature transmitter with thermocouple or thermal resistor is a temperature transmission unit of DDZ-S series instrument. It combines thermocouple or thermal resistor with transmitter to measure temperature of liquid, vapor and gas media within －200～1600℃. It will convert thermocouple or thermal resistor signal into 4～20mA output signal and send to display, recording instrument or computer.
Explosion-proof performance of explosion-proof, intrinsically safe thermocouple (resistance) temperature transmitter is manufactured according to GB3836 standard. Thermoelectric properties are in line with international IEC standards, and tested by the National Explosion-proof Safety Supervision Station. As a new type of temperature transmitter, it is widely used in metallurgy, petroleum, chemical, electric power, light industry, textile, food, defense and scientific research departments.
