QUALITROL CAB-699 Fiber optic temperature probe
Field proven high accuracy probe for measuring hot spot temperature

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.
- Direct measurement inside transformer yields highly temperature readings reducing risk of failure or unnecessary reduction in transformer life
- Over 4000 installed
Long term, drift-free survivability
- All materials are chemically and dielectrically resistant
- ST type connectors resist failure due to vibration
Does not require recalibration or complex input to operate
- Galium arsenide (GaAs) measurement principle
Surpasses ASTM dielectric strength standards for use inside transformers
- Unique, patent-pending longitudinal slit enables uniform contact with transformer oil over entire probe length
For use inside oil-filled or dry-type electrical transformers. Compatible with QUALITROL® intelligent transformers monitors with direct winding.
