Add Product to My Catalog

Robust, oil-permeable Neoptix T2™ temperature probes for highly accurate measurement of power transformer temperatures.

Installed within standard spacer or directly onto any other location inside transformer windings to directly measure ‘hot spot’ temperature.
Features
  • Direct measurement inside transformer yields highly temperature readings reducing risk of failure or unnecessary reduction in transformer life
  • Over 35,000 installed worldwide
  • All materials are chemically and dielectrically resistant
  • ST type connectors resist failure due to vibration
  • Galium arsenide (GaAs) measurement principle
  • Unique, patent-pending longitudinal slit enables uniform contact with transformer oil over entire probe length
