Type Characteristics

Analog Potential Transmitter: Outputs analog signals, such as voltage or current signals, with high accuracy and resolution, suitable for measuring and controlling continuously varying physical quantities. However, analog signals are susceptible to interference during transmission and have limited transmission distances.

Digital Potential Transmitter: Converts potential signals into digital signals for transmission and processing, offering advantages such as strong anti-interference capability, long transmission distances, and ease of interfacing with digital devices like computers. However, digital potential transmitters are relatively costly and impose stricter requirements on sensors and signal processing circuits.

Application Areas

Industrial Process Control: Used to monitor and control physical quantities in various industrial production processes, such as temperature, pressure, flow rate, and liquid level, enabling automated control and optimization of production processes to improve efficiency and product quality.

Environmental Monitoring: Can be used to monitor parameters like temperature, humidity, and pH levels in the environment, converting these parameters into potential signals and transmitting them to monitoring centers for timely awareness of environmental changes and implementation of appropriate environmental protection measures.

Electronic Measurement Instruments: In various electronic measurement instruments, potential transmitters can convert measured electrical or non-electrical quantities into electrical signals that are easy to measure and display. Instruments such as voltmeters, ammeters, and oscilloscopes may utilize potential transmitters.
