63mm tube wall thermometer is an industrial thermometer designed for measuring the surface temperature of pipes, tanks, or other cylindrical vessels. Here's a detailed explanation in English:
Key Features:
1. 63mm Diameter
- The thermometer has a 63mm (2.5-inch) dial, making it large enough for easy reading from a distance.
2. Tube Wall Mounting
- Designed to be installed directly on pipes or tank walls using a stem or threaded connection (e.g., bimetal or liquid-filled design).
- Common mounting styles:
- Insertion stem (for direct contact with the medium inside the pipe).
- Surface-mounted (attached to the outer wall for external temperature monitoring).
3. Temperature Range & Accuracy
- Typical ranges: -20°C to +400°C (-4°F to 752°F), depending on the sensor type (bimetal, gas-actuated, or liquid-filled).
- Accuracy: Usually ±1% to ±2% of full scale.
4. Durable Construction
- Stainless steel case for corrosion resistance.
- Shock and vibration-resistant for industrial environments.
5. Common Applications:
- HVAC systems (monitoring pipe temperatures).
- Industrial process control (chemical, oil & gas, food processing).
- Boilers, heat exchangers, and steam lines.
Types of 63mm Tube Wall Thermometers:
- Bimetal Thermometers: Mechanical, cost-effective, no power needed.
- Liquid-Filled Thermometers: Better for high-vibration environments.
- Gas-Actuated Thermometers: Used for higher temperature ranges.
Installation Notes:
- Ensure proper thermal contact (e.g., using thermal paste for surface mounts).
- For insertion types, the stem length should match the pipe diameter.
