Qualitrol 120 Side-Mount Thermometer with 6″ Dial

Bourdon Tube Thermometer

Qualitrol 120 Side-Mount Thermometer with 6″ Dial (152.4 mm) is a bourdon tube thermometer equipped with a reset-able maximum temperature pointer and up to 4 adjustable switches (contacts) for control and alarm functions. The Qualitrol 120 Side-Mount Thermometer can be installed in an optional well to allow units to be replaced without lowering the oil level in the tank or disturbing the tank seal.

Features

Bourdon tube measurement with resettable maximum pointer
Up to 4 user adjustable switches (contacts) for control and alarms
6 inch (150mm) dial face with an angular dial span of 90° for easy viewing
Built in spring loaded pointer for switch field testing
Large dial face for maximum readability
UV-stabilized polycarbonate lens (resists yellowing with age) for lifetime readability
Durable design for survivability in harsh environments
Molded neoprene channel gasket is uniformly clamped in place, protecting against water entry around entire lens
Free-breathing housing reduces internal condensation buildup. Dual breathers act as vacuum breaker to prevent unwanted moisture intake
Magnetically coupled maximum pointer is integral with lens for ease of resetting and moisture path elimination
Rugged construction with corrosion resistant materials
Die-cast aluminum housing resists corrosion with two-part, long-life epoxy finish
Up to four switches (contacts) can be set by the factory or can be easily set or changed in the field
Dial temperature range, number of switches (4 maximum), switch settings and wiring, electrical connection type, cable/wire types and lengths, probe dimensions, and thermo well characteristics can all be customer specified to meet specific application requirements
Mounts directly onto well (pocket)
“One-screw” access; bezel clamp and lens easily removed to reach switch settings and ‘quick-test’ mechanism.
Maximum temperature pointer follows indicating pointer upward and remains at hottest reading to track high temperature levels. Resets easily with magnetically coupled knob on face of lens
‘Quick-test’ feature enables simple testing of switch actuation and related controlled transformer functions by moving indicating pointer clockwise through switch settings. The no-stress, spring-loaded clutch prevents damage to internal thermometer components

Options

Temperature ranges applicable for oil (liquid) or winding (winding simulation requires heated well or Qualitrol Thermal plate)
Up to 4 switches
Probe length and compatible well
Electrical connection type, connector cable type and wire colors

Applications

For temperature indication with integrated control or alarm functions. Designed for use where the point of measurement (the well or pocket) is on the side of the apparatus and can be easily viewed.
