Bimetal Thermometer Afriso BiTh100 40 mm 0–160°C 1/2" axial connection

Afriso BiTh100 is a bimetal dial thermometer with a compact 40 mm case and a measuring range from 0 to 160°C. The instrument uses a bimetal sensing element to provide a direct mechanical temperature indication without the need for power. With a 1/2" axial connection, the thermometer is designed for direct mounting into pipes, fittings or equipment where local temperature monitoring is required. The construction is suited to heating systems, industrial processes and HVAC applications where a simple, rugged temperature indicator is needed.

Advantages

The thermometer offers a maintenance‑free bimetal mechanism that delivers stable, repeatable readings over its operating range. Its small 40 mm diameter case allows installation in confined spaces while the axial 1/2" connection provides straightforward mechanical mounting into pipework or threaded ports. Because it operates mechanically, it does not require electrical supply or sensors, reducing installation complexity and potential failure modes. The clear dial and calibrated scale from 0 to 160°C enable quick visual checks of process or system temperatures.

Suitable for

• Local temperature monitoring in heating systems
• Temperature checks on industrial equipment and machines
• HVAC installations and control panels
• Mounting into pipework or threaded ports requiring a compact indicator

Key specifications

• Measuring range: 0–160°C
• Case diameter: 40 mm
• Connection type: axial 1/2" threaded connection
• Sensing element: bimetallic coil
• Indication: analogue dial with calibrated scale
• Power: mechanical operation, no electrical supply required

How to use

Mount the thermometer into a prepared 1/2" threaded port on the pipe, tank or equipment so the axial connection is correctly engaged and the dial is visible for reading. Ensure the sensing element is in contact with the medium or the vessel wall for accurate temperature transfer. Tighten the connection to provide a secure mechanical fit without over‑torquing; use appropriate sealing material if required by the installation. Read the temperature from the analogue dial; the bimetal element translates temperature change into pointer movement across the 0–160°C scale.

Usage recommendations

For reliable readings, install the thermometer where it is exposed to the representative process temperature and avoid locations subject to excessive vibration or mechanical shock. If used in piping, position the probe so fluid flows around the connection point to improve thermal contact. Regular visual inspection is sufficient for maintenance; do not attempt to modify the bimetal sensing element or dial. Where higher accuracy, remote reading or electronic control is required, consider complementary sensors or transmitters designed for integration with control systems.
