Qualitrol CAB-699 Fiber optic temperature probe

Description

Direct measurement inside transformer yields highly temperature readings reducing risk of failure or unnecessary reduction in transformer life.
Over 35,000 installed worldwide.
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.
