RFID POWER SYSTEM PASSIVE WIRELESS TEMPERATURE MONITORING SYSTEM

Johar developed a passive wireless power temperature monitoring system based on UHF RFID sensors. It is battery free, long life cycle, stable, maintenance-free, and wireless. It can monitor the temperature of the key nodes of power equipment in real time without affecting the insulation and safety of power system. The sensor has a wide measurement range (- 40 ~ +150 ℃), small sensing error (less than ±1 ℃); the overall flame-retardant grade is = ul94-v0; and it can resist up to +220 ℃.

POWER SYSTEM PASSIVE WIRELESS TEMPERATURE SENSORS

1. Good high and low temperature resistance;
2. Chip level temperature measurement, high stability and no crash in long-term use;
3. Long service life and maintenance free. It can achieve the same service life as the measured electrical equipment;
4. The protection grade can reach IP68, which is suitable for various outdoor environments;
5. It is installed close to the hot spot, and the temperature measurement is more accurate;
6. High temperature measurement acquisition frequency and strong real-time performance. It can collect temperature data every 100ms ;
7. The chip external lead supports non-contact telemetry, which can be used for temperature measurement in confined spaces such as cable trench and cable connection;
8. Both AC and DC equipment are applicable

TEMPERATURE COLLECTOR

Based on Impinj R2000 chip, the collector has the best receiving sensitivity and anti-interference ability; DC 12-36V wide power supply design makes it easy to meet the diverse power supply conditions in the field. Two independent RS 485(Modbus RTU protocol) communication interface makes remote upload and local display possibe. Expandable 4/8 -port antena interface to meet economical equipment;active working mode, no additional operation required after restarting.
