TSENS-K
Fiber Optic Temperature Sensor
Accurate Monitoring Designed to Outlast Transformers
Transformers depend on accurate temperature data to mitigate aging caused by thermal stress and insulation degradation. The Kevlar-reinforced TSENS-K offers a durable and easy-to-install design, ensuring long-term temperature monitoring. It provides manufacturers and operators with reliable data critical for accurate transformer aging evaluation, proactive maintenance, and consistent performance.
- Designed for easy installation in oil-filled and dry-type transformers and reactors.
- Built with rugged construction to exceed transformer lifespans.
- Zero-drift GaAs technology ensures outstanding repeatability and reliable performance.
- Compact 9 mm disc design, suitable for various transformer locations (windings, cores, busbars, tap changers, etc.).
- Resistant to solvents and chemicals for enhanced durability.
- Kevlar reinforcement along the entire probe length for enhanced strength and reliability.
- No calibration required, offering consistent and maintenance-free performance.
- Exceptional stability with no shift over time, ensuring high accuracy.
- Durable construction with double PFA Teflon reinforcement and a robust sensor tip for reliable operation.
- Versatile design, available with or without a disc, suits various applications.
- Meets and exceeds ASTM D2413 and D149 standards for superior quality.
- Engineered for minimal partial discharge, delivering low PD levels.
- Designed for long-term reliability and outlasting transformer lifespans.
- Suitable for power transformers, both oil-filled and dry-type.
- Enables precise direct temperature measurements.
- Suitable for high-voltage environments (1 MV or more).
- Ideal for HVDC windings.
- Mountable in standard radial spacers.
- Withstands kerosene desorption.
- Works with all transformer oils, including ester based.
- Compatible with Rugged Monitoring instruments.
