Bimetal Thermometer Afriso Ø 63 mm model 63801 — dial temperature gauge 63mm

The Afriso bimetal thermometer model 63801 is a compact dial temperature gauge with a 63 mm diameter face designed for panel mounting and local temperature indication. It uses a bimetallic sensing element to provide direct mechanical readout without requiring electrical power, making it suitable for continuous monitoring in heating, ventilation and air conditioning (HVAC) systems, boilers, industrial equipment and process control. The instrument delivers straightforward temperature readings with a clear scale and robust construction for routine operational use.

Advantages

The bimetal design ensures stable and reliable temperature indication with minimal maintenance and no dependency on electrical supply or batteries. Its 63 mm dial offers good readability in compact installations, while a durable housing and simple mounting format make it practical for panel or surface installation. The mechanical operation is inherently resistant to electrical interference and provides an immediate visual indication of temperature changes.

Suitable for

• Local temperature monitoring on control panels and instrument panels
• Boiler temperature indication and heating system checks
• HVAC system components and duct or pipe monitoring
• Industrial machinery and process equipment requiring a compact gauge

Key specifications

• Dial diameter: 63 mm for compact panel integration
• Sensing element: bimetal coil providing mechanical temperature response
• Display type: analog pointer with printed scale for direct reading
• Mounting: panel/surface mounting suitable for control panels and enclosures
• Power: purely mechanical operation, no electrical supply needed
• Construction: rugged case and dial designed for industrial and HVAC environments

How to use

Install the thermometer in a prepared panel cut-out or surface mount location where the dial is easily visible. Ensure the sensing element is correctly positioned in contact with the medium or thermowell as required by your application; in pipe or boiler installations, use an appropriate pocket or thermowell to protect the sensing element and improve response. After mounting, verify the pointer moves freely across the full scale and compare readings with a reference instrument if calibration verification is needed. No electrical connections are required.

Usage recommendations

For accurate and durable performance, avoid exposing the instrument to excessive vibration, aggressive chemicals or temperatures beyond the specified operating range. Use a protective thermowell when measuring fluids under pressure or corrosive conditions, and periodically inspect the mounting and dial for mechanical damage or obstructed pointer movement.
