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. 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.
