Designed for power transformer or load cap changers
A fibre optic temperature sensor designed for power transformer or load tap changers temperature monitoring. Using optical absorption within a semiconductor (GaAs), it combines long-term reliability with high accuracy. Its flexible fiber optic cable and rugged PTFE exterior allow easy and safe installation in transformer windings & core, as well as in LTCs. Immune to RFI and EMI, the TPT-32 sensor can withstand harsh chemical environments.
