background
Weighing sensors are widely used in industrial, commercial, and medical equipment, especially in high-precision weighing and dynamic load monitoring scenarios. These sensors typically use strain gauge technology to detect the weight or load of objects. It is crucial to protect strain gauges from external environmental influences in order to ensure their precise operation and long-term stability. Especially in harsh working environments such as high humidity, vibration, and temperature changes, strain gauges require effective protective measures to avoid damage or functional degradation.
Application requirements
In such applications, the main requirements of users are:
Protecting strain gauges: As the core component of sensors, strain gauges must maintain high sensitivity and accuracy, and cannot be disturbed by external environments such as moisture, dirt, etc.
Good insulation: As weighing sensors involve electrical measurements, good electrical insulation performance is crucial to avoid electrical interference and errors.
Flexibility: Due to the mechanical stress that strain gauges need to withstand, the protective adhesive layer must have sufficient flexibility to reduce mechanical stress caused by vibration or temperature changes.
Viscosity requirement: In order to ensure that the adhesive dots can evenly cover the surface of the strain gauge, the viscosity range should be controlled between 12000-15000 CPS to ensure the uniformity and flowability of the coating.
