A bimetallic thermometer is an industrial instrument that measures temperature based on the principle of thermal deformation differences between two metals with different coefficients of linear expansion. It is primarily used for on-site temperature measurement of liquid, steam, and gas media in the range of -80℃ to +500℃.
Its core component is a multi-layered spiral metal strip. Temperature changes cause bending deformation, which drives the pointer to indicate the temperature. It features strong vibration resistance and high mechanical strength, with an accuracy class of 1 to 2.5. The instrument is available in axial, radial, 135° angle, and universal types, and supports various installation methods such as movable external threads and fixed flanges. It has an IP55 protection rating and a protective tube pressure rating of 6.3 MPa.
Vibration-resistant models utilize silicone oil filling or component separation design, making them suitable for various industrial applications such as pipelines and containers.
They are ideal for temperature monitoring and control in medium and low-temperature environments in industries such as petroleum, chemical, and metallurgy. The bimetallic strip, as a temperature-sensing element, can also be used in automatic temperature control systems to achieve automated temperature regulation in industrial settings.
The WSS series bimetallic thermometer is an on-site measurement instrument for medium and low temperatures. It can directly measure the temperature of liquid, steam, and gas media in the range of -80℃ to +500℃ in various production processes.
