For temperature monitoring of transformers, reliable temperature monitoring is possible without being affected by noise from EMI/RFI or high voltage environments.
OSENSA's fiber optic temperature sensor for transformers enables real-time temperature monitoring of transformers without being affected by noise in environments with EMI/RFI or high voltage. The basic configuration of this product consists of a temperature sensor probe, transmitter, and software. The PRB-230 probe is designed for temperature measurement in oil-filled transformers and accommodates immersion and removal processes for various types of transformer oil. The transmitter is available in a type that can connect multiple probes with a single unit, allowing for simultaneous measurement of temperatures at multiple points.
