Weighing sensor is a kind of mass (weight) measurement method that converts mass (weight) into electricity through the stressed structure. The output electric quantity signal and the input quality (weight) signal have a single value linear correspondence; It has the required accuracy and high sensitivity; It has good frequency response characteristics and less inertia; Little influence on the state of the weighed object; Able to work in poor environmental conditions; Good stability, reliability and long service life.
020-34563445Weighing sensor is a sensor of a device or device that uses the physical characteristics of a material or element related to temperature to convert the temperature change into the electric quantity change. The explosion-proof weighing sensors commonly used in measurement are thermocouples and thermal resistors. Thermocouples convert temperature changes into potential changes, while thermal resistors convert temperature changes into resistance changes. In addition, the junction-based transistors and integrated weighing sensors of Weighing modules have also been rapidly developed and widely used.
By adjusting the stress consistency of sensors, the weighing module can reduce the influence of "static uncertainty" of multi-fulcrum balance of the platform and ensure the stability of the platform support, so as to ensure that the bearing capacity of the center of gravity of the platform does not deviate, and achieve the accuracy of the weighing instrument and the relevant metering performance requirements. The weighing module has been compensated in many ways, including output sensitivity compensation.
The protection level of the weighing sensor IP68 can work in various harsh environments. The spherical connector always keeps the vertical weighing state of the module, which prevents the equipment from overturning. The installation is simple, fast, easy to maintain and saves downtime and maintenance time.
