Qualitrol 120 Direct Mount Thermometers, Certification : ISO 9001: 2015

Large dial face for maximum readabilitySide mounting bourdon tube thermometers equipped with a 6" (152.4 mm) dial face for temperature indication. Features a resettable 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 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:

• Large 6 in (152.4 mm) dial face with large graduations and letters for optimal legibility
• UV-stabilized polycarbonate lens (resists yellowing with age) for lifetime readability

Durable design for survivability in harsh environments:

• UV-stabilized polycarbonate lens for high-impact strength. Securely fastened in place with stainless steel bezel ring and stainless steel hardware
• UL and CSA recognized switches
• 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 4 adjustable switches:

• Up to four switches (contacts) can be set by the factory or can be easily set or changed in the field
• Switches feature lockdown screws to resist tampering and vibration
• Two switches can be set to trigger at the same temperature

Easy to install and operate:

• 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
