TSENS

TSENS

Precisely designed for probe robustness and ease of installation to get reliable, long-term temperature data, essential for accurate transformer aging evaluation.

KEY FEATURES

  • Optimized for easy installation in oil-filled and dry-type- transformers and reactors
  • Rugged and robust construction built to outlast your transformer life
  • Outstanding repeatability, zero-drift GaAs technology
  • 9 mm disc design, suitable for all locations in a transformer (windings, cores, busbars, tap changers, etc.)
  • Solvent and chemical resistant

Precisely designed for probe robustness and ease of installation to get reliable, long-term temperature data, essential for accurate transformer aging evaluation.

Rugged Monitoring Tsens probes have been designed and built to incorporate in transformers to give precise results (direct measurements of temperature). The sensing technology is based on the proven zero-drift GaAs technology. They are completely built using first quality materials, with very high dielectric strength, to provide accurate temperature readings of transformers, which is essential to a good knowledge of transformer aging rate. 
The probes will give both transformer manufacturer and operator invaluable information regarding the transformer expected MVA performance during a factory heat run tests.
