120 Side Mount Thermometer with Large Dial

Brand: Qualitrol Company

Side mounting bourdon tube thermometers equipped with a 6" (152.4 mm) dial face for temperature indication.

Features a reset-able maximum temperature pointer and up to 4 adjustable switches (contacts) for control and alarm functions.

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" (150 mm) 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
