Product Description
Product Overview Product overview
The LPT-C series intelligent differential pressure transmitter adopts a microprocessor core modular design in circuit design, which has good anti-interference performance. The internal configuration of the temperature sensor compensates for the transmitter, improving measurement accuracy and reducing temperature drift, with characteristics such as long-term stability, high reliability, and strong self-diagnosis capability. Users can calibrate, set, and configure the transmitter through the HART communication handheld device. The interface is fully designed in Chinese, with different password permissions, making it convenient for users to set. It is widely used in chemical, metallurgy, water conservancy, electric power, petroleum, and other occasions.
