Features
Bourdon tube based capillary measurement with resettable maximum pointer
Up to 2 user adjustable switches (contacts) and one additional fixed switch for control and alarms
5 inch (130 mm) dial face with an angular dial span of 120° for easy viewing
Low profile probe can be dressed for use in dry type transformers
Minimize the space required for remote indication
75″ (146 mm) outer case diameter for small installation footprint
120° dial deflection (angular range of pointer) and 5″ (127 mm) dial face for easy interpretation of measurement
Control cooling, alarms and other auxiliary equipment
Up to 2 user adjustable switches (contacts) and one additional fixed switch (set by the factory) for control and alarms
Multiple switches can be set to actuate at same temperature and lockdown screws reduce the effects of vibration and tampering on the switch settings
UL and CSA recognized switches
Increase reliability with rugged design and corrosion resistant materials
Vented (free-breathing) models feature dual breathers that act as vacuum breakers to prevent unwanted moisture intake
Molded neoprene channel gasket uniformly clamped in place with a powder coated, die-cast aluminum bezel ring and stainless steel hardware, sealing against water entry around entire lens
Reset knob magnetically coupled through front of lens reduces the possibility of moisture entry
UV-stabilized polycarbonate lens has high-impact strength and resists clouding and yellowing with age
Double-braided armored capillary tube withstands environmental extremes
Die-cast aluminum housing resists corrosion with two-part epoxy finish
Simplify installation and operation
Mounts directly onto the transformer or to shock mount
“Quick-test” feature simplifies switch actuation and corresponding controlled function testing-to use, simply move the indicating pointer through the dial range, past switch settings, and note proper operation
“Quick-test” features a no-stress spring-loaded clutch to prevents damage to internal mechanism during testing
Maximum temperature pointer follows indicating pointer upward and remains at hottest reading to track high temperature levels until reset
Options
Temperature ranges applicable for oil (liquid) or winding (winding simulation requires heated well or Qualitrol Thermal plate)
Up to 3 switches
Tank connection style. probe length, and compatible well
Capillary length, material and protective housing
Electrical connection type, connector cable type and wire colors
Applications
For temperature indication with integrated control and alarm functions. Designed for use where the point of measurement (the well or pocket) is on the side or top of the apparatus and can be easily viewed.
