SBWZ series thermocouple temperature transmitter and SBWZ series thermal resistance temperature transmitter are the field mounted temperature transmitting unit in DDZS series instrument. It uses a two-wire transmission mode (power input and signal output for the two common wire), the output and the measured temperature performance of the 4-20mA current signal. The transmitter can be arranged in the junction box of the thermocouple and the thermal resistance to form an integrated structure with the utility model, and the utility model can be separately arranged on the instrument panel as a conversion unit. As a new generation of instrument, can be widely used in petroleum, chemical, textile, metallurgy, machinery, electric power, aviation, food processing, medical engineering and other industrial and scientific research in the field of automation, temperature detection, transmission and control.
