It provides fully insulated, shielded electrical connections for the equipment bushings. The product incorporates a wireless, passive temperature sensor that transmits real-time data on the temperature of the high-voltage conductor within the connector to external devices for monitoring purposes and ensuring safe equipment operation.

Product Description

Product Features

1. World's first, RFID passive temperature sensing

2. Truly passive: Battery-free, no power required for the CT scanner.

3. Digital measurement, digital transmission, CRC error correction

4. Unique sensor ID, infinitely expandable

5. MODBUS RTU Communication Protocol

Passive wireless temperature measurement principle: The temperature collector uses an antenna to emit radio frequency waves. These waves activate the sensor and simultaneously transmit temperature measurement commands. After activation, the sensor starts the temperature measurement circuit and sends the measurement result to the collector. The entire process uses digital protocol communication and digital transmission, with CRC checksum error correction, ensuring stable and reliable communication. Passive sensor in RFID integrated temperature measurement chip: The core is a miniature IC, integrating RFID communication and temperature measurement. No external temperature measurement components are needed. It has a unique ID, and ultra-low power consumption enables long-distance reading. Combining low-power technology and wireless power supply sensing technology, it achieves battery-free, CT-free, digital measurement, and digital transmission passive wireless temperature measurement. This eliminates battery risks and solves the weaknesses of SAW (Surface Acoustic Wave) temperature measurement, such as susceptibility to interference and misreading.
