▎System introduction    
     The passive wireless online temperature measurement system is a high-tech temperature measurement product independently developed by our company. This temperature measurement system is designed for temperature monitoring of the contacts and busbar connections of high-voltage switch cabinets, bus joints, outdoor knife switches and other equipment in power plants and substations.
      This system uses induction power technology to easily obtain the stable required working power from the contact arm and busbar line, fundamentally solving the trouble of replacing batteries during maintenance. The system has excellent shielding technology and strong anti-interference ability, ensuring that the signal is transmitted to the corresponding receiving device accurately and in real time.
▎System features
1. The sensor adopts the principle of electromagnetic induction and provides independent power supply.
--Avoid battery replacement and greatly reduce maintenance costs
2. On-site sensors are highly interchangeable
--The ID number and alarm threshold of each sensor can be changed remotely
3. Sensor contact temperature sensing

--Accurately reflects the actual temperature of the measured location

4. Wireless communication between sensor and display

--Complete isolation of high and low voltages, no insulation hazards

5. A single display can receive multiple (up to 256) sensor data

--Two system modes , distributed and centralized, are available for you to choose from, suitable for different temperature measurement needs.

6. Supports various data protocols such as Modbus and IEC61850

--Data can be uploaded to the comprehensive management system to facilitate intelligent management

7. Convenient and rapid implementation

--The product is easy to install, easy to implement, simple to operate, and quick to put into operation
