Product Overviews

Kaifeng Instrument WBS series integrated temperature transmitter (hereinafter referred to as the instrument) is developed first by our company. After launching into the market in 1985, with 20 years of constant improvement, it features the integrated structure of sensor or transmission circuit at home. It adopts thermal resistor or thermocouple as the temperature sensitive elements, adopts special circuit module to convert the local signal of sensitive element into the standard current which is linear with temperature, the signal can be transmitted with common copper cable, which can save the precious compensation wire or cable, and features low signal transmission distortion, strong anti-interference ability with far transmission. It is very convenient to connect with varied secondary instrument or computer system for temperature measurement and control.
