| Description de l'article | Lora temperature sensor / PMC-2601-A CAN be flexibly applied in medium/high voltage and current scenarios and CAN monitor the temperature of the medium and high voltage equipment such as moving and static contacts, BUSBARS, and cable inlets and outlets in real-time. The device uses an ultra-low induction current to draw power and CAN be used without an external power supply or built-in battery. The device has a built-in B3950 10K 1% high-precision NTC thermistor, combined with an internal 10PPM low-temperature drift 0.1% high-precision 10K sampling resistor, which CAN provide a temperature measurement accuracy of up to ±1°C. The built-in lora wireless transmission method transmits temperature and humidity data over long distances |
