【Product Introduction in English】

The WSS-483L Thermowell Bimetallic Thermometer is a mechanical temperature measurement instrument designed for industrial process monitoring. Utilizing bimetallic sensing technology based on thermal expansion principles, this device provides reliable temperature indication for steam pipelines, heat exchangers, reaction vessels and other applications requiring long-term stable measurement.

Constructed with stainless steel housing, the instrument features shock-resistant dial design and fully enclosed casing that effectively prevents moisture and dust ingress. With a temperature range spanning from -20℃ to +500℃, it offers both axial and radial dial orientations. The standard 100mm dial comes with two display options: black markings on white background or red markings on ivory background, ensuring clear readability. Tempered glass window enhances thermal resistance and impact tolerance.

Equipped with detachable thermowell assembly, the product facilitates easy field maintenance and sensing element replacement. Multiple international thread specifications including G1/2 and NPT1/2 are available for pipeline compatibility. The built-in overload protection mechanism minimizes mechanical damage risks during sudden temperature fluctuations.

This thermometer is particularly suitable for vibration-intensive environments and applications involving medium erosion, finding wide usage in petrochemical, power generation, and food/pharmaceutical industries. Through optimized elastic modulus matching of bimetal strips, it achieves smooth pointer movement and stable indication retention. The IP65 protection rating ensures reliable operation in outdoor or humid conditions.

Manufacturers offer customization services including special range configuration and interface dimension adjustment. Each unit undergoes rigorous quality control processes including material composition analysis, indication calibration and sealing performance verification prior to delivery.
