Bimetallic thermometer F+R 801 R63/50 120°C with 1/2 inch rear connection PT30507018

Bimetallic thermometers, although simple in construction, are a reliable solution for temperature measurement in many applications. This model from F+R, designated 801 R63/50, is a proven choice for both installers and end-users who need a precise and durable device.

Characteristics and application

This bimetallic thermometer with a 1/2 inch rear connection is designed to operate in a temperature range of 0 to 120°C. Accuracy class 2.0 ensures reliable readings under various conditions. The housing diameter is 63 mm, and the pin made of galvanized steel has a diameter of 9 mm – this combination guarantees strength and corrosion resistance. The rear connection facilitates mounting in existing installations.

Bimetallic thermometers of this type are used in heating systems, boilers, storage tanks, and also in industrial processes requiring temperature monitoring. They are particularly useful where there is no access to electrical power or where reliability without electronics is required.

Construction and benefits

The construction based on bimetal – a combination of two metals with different coefficients of thermal expansion – ensures direct and mechanical temperature measurement. A change in temperature causes the bimetal to bend, which is translated into an indication on the scale. The simple construction translates into high reliability and long device life. Galvanized steel used to make the pin protects against the effects of moisture and corrosion, which extends the service life of the thermometer even in harsh environmental conditions. The 1/2 inch rear connection allows for easy integration with existing pipeline or tank installations.
