Micro water density online monitoring system manufacturer

The system adopts advanced sensing technology, microcontroller technology, modern physical analysis theory, control theory, and communication technology achievements, and has multiple innovative technologies with independent intellectual property rights, such as continuous detection technology for trace moisture and density of gas under changing environmental temperature and pressure in sealed pressure vessels. It belongs to the field of online monitoring and control of SF6 gas moisture and density in power SF6 high-voltage circuit breakers. The system connects information to the comprehensive automation system of the substation through the RS-485/CAN communication interface. The built-in two sets of output conversion contacts can upload alarm and locking signals according to preset thresholds, or directly activate alarm and locking devices.
The micro water sensor adopts a polymer film dew point sensor, and the density uses a sensor with original laser correction from the United States, ensuring the overall measurement accuracy and stability.
