Product details
The SBW □ series integrated temperature transmitter with thermistor/thermocouple is an integrated on-site installation transmitter unit for DDZ-S series instruments, mainly composed of a temperature sensor (thermistor or thermocouple) and a two-wire temperature change module. (Additional current display meter for display type products), capable of temperature detection, transmission, and display on solid surfaces, liquids, and gases. Widely used in industries and scientific research fields such as petroleum, chemical, metallurgical, power, electromechanical, textile, food, medicine, etc., it integrates temperature sensing, transmission, and display.
characteristic
The temperature transmitter module is encapsulated with epoxy resin, which is corrosion-resistant and vibration resistant. And the static power consumption is weak, safe and reliable, with a long service life.
Adopting a two-wire transmission system, it has strong anti-interference ability and a long transmission distance.
Equipped with cold end compensation and nonlinear correction, the output signal has a linear relationship with the measured temperature.
It can directly display the measured temperature on site with a display head, and can be used in conjunction with secondary instruments or directly input into the computer control system.
