Overview
The LYZ series thermistor temperature transmitter converts the input thermistor signal into a standard DC current signal or DC voltage signal required by the user through linear correction isolation, and the power supply, input, and output are isolated from each other.
Product Details
1、 Overview of LPT-S series pressure transmitters:
The LPT-S series intelligent pressure transmitter adopts a microprocessor core modular design in circuit design, which has good anti-interference performance. It is equipped with an internal temperature sensor to compensate for the transmitter, improve measurement accuracy, reduce temperature drift, and has the characteristics of good long-term stability, high reliability, and strong self diagnostic ability. Users can calibrate, set up, and configure the transmitter through the HART communication controller. The interface is designed entirely in Chinese, with different password permissions that users can easily set. Widely used in chemical, metallurgical, water conservancy, power, petroleum and other fields.
