Zedeyes 422 Industrial gas actuated Thermometer

The Zedeyes 422 is a gas-actuated remote reading capillary thermometer engineered for measuring temperature in hard-to-reach locations, hot media lines, or hazardous process points. By connecting the remote sensing stem to a panel-mounted or wall-mounted dial via a flexible capillary line, the Zedeyes 422 allows centralized monitoring—enabling multiple process temperature dials to be grouped on a single control panel for rapid visual comparison.

Constructed entirely from stainless steel (SS304 case and SS316 stem), the instrument utilizes an inert gas-actuated Bourdon tube system to deliver fast response times across extensive temperature ranges up to +650 °C. For installations subject to heavy mechanical vibration, the housing can be liquid-filled (silicone oil or food-grade oil for hygienic applications) to ensure steady, reliable dial readings.

Key Features & Benefits

• Remote Process Monitoring: Flexible capillary tubing allows the gauge display to be installed in accessible, safe, and centralized panel locations away from high heat or tight equipment spaces.

• Full Stainless Steel Construction: Durable SS304 housing combined with a SS316 stem provides exceptional corrosion resistance in chemical and marine environments.

• Fast Response Gas-Actuated System: Inert gas fill delivers fast thermal response speeds and a linear scale readout across broad operating ranges (−60 °C up to +650 °C).

• Vibration-Damped Liquid Filling Option: Case can be filled with silicone oil (or FDA-approved food-grade oil) to dampen pointer flutter in high-vibration environments.

• Flexible Capillary & Stem Lengths: Available with capillary lengths of 1, 3, 6, or 10 meters and custom stem configurations to meet specific vessel or pipe immersion depths.

• High Measurement Accuracy: Guarantees consistent accuracy across the full scale span (Class 1 or Class 2 per EN 13190 standards).

Primary Applications

• Chemical & Petrochemical Processing: Remote temperature tracking for reactors, distillation columns, and aggressive fluid lines.

• Food & Beverage Industry: Sanitary temperature monitoring in tanks, breweries, and food processing equipment using food-compatible oil fills.

• Machine Building & Plant Piping: Engine skids, heat exchangers, boiler headers, and OEM machinery.

• Refrigeration & HVAC Systems: Chilled water loops, industrial freezers, and climate control ductwork.
