Bimetal Thermometer Afriso BiTh 100 mm 0–120°C with 63 mm Immersion Sleeve and 1/2" Connection (63812)

Mechanical bimetal thermometer Afriso BiTh with a 100 mm dial and a measuring range of 0–120°C. The instrument is supplied with a 63 mm immersion sleeve and a 1/2" process connection for secure mounting in pipes, boilers or tanks. The robust bimetal sensing element converts temperature changes into a direct pointer indication, providing maintenance-free monitoring of liquid or air temperature in heating and industrial systems.

Advantages

The bimetal thermometer offers a clear 100 mm dial and a calibrated scale for quick visual reading. Its mechanical design requires no external power and ensures stable operation in typical heating and industrial environments. The included 63 mm immersion sleeve protects the sensing element from direct contact with the medium while enabling reliable temperature transfer. A 1/2" threaded connection simplifies installation and replacement in standard process fittings.

Suitable for

• Temperature monitoring in heating systems and boilers
• Pipeline and tank temperature control in industrial installations
• Applications where electrical power for sensors is not available or desired
• Retrofit or replacement of mechanical temperature indicators

Key specifications

• Dial diameter: 100 mm
• Measuring range: 0–120°C
• Sensing element: bimetal coil (mechanical)
• Immersion sleeve length: 63 mm
• Process connection: 1/2" threaded
• Mounting: direct insertion via sleeve for pipe, boiler or tank applications

How to use

Insert the immersion sleeve into the process connection point and secure the thermometer by tightening the 1/2" threaded fitting. Ensure the sleeve reaches the medium so the bimetal element can sense the representative temperature; the sleeve length of 63 mm limits insertion depth. After installation, allow the system to stabilize and read the pointer position against the calibrated 0–120°C scale. No electrical connection or special commissioning is required.

Usage recommendations

For accurate and durable performance, install the thermometer in a location with stable flow around the sleeve and avoid direct exposure to strong vibrations. Where aggressive or corrosive media are present, use an appropriate protective sleeve material or consult material compatibility information. Periodic visual checks and comparison with a calibrated reference instrument are recommended to verify long-term accuracy.
