What is weighing transducer?


The integrated strain gauge converts the elastic deformation of the weighing transducer (caused by the weight load) into an electrical signal proportionally.

  What is a weighing transducer?

  The design of the weighing transducer is a special form of force sensor used in weighing technology. The measured force value is converted into an electrical output signal or local mechanical indication. The calibration is performed in grams, kilograms, or tons, rather than in Newtons as usual force measurements. The integrated strain gauge converts the elastic deformation of the weighing transducer (caused by the weight load) into an electrical signal proportionally. This achieves a very high measurement accuracy between 0.01% and 0.05% From.

  Working principle of weighing transducer

  In order to meet the needs of most industrial applications, a weighing transducer uses three important measurement techniques. Thin-film technology uses resistive grids to convert pressure values ​​into redundant output signals. The measuring bridge and the cell body are connected by a sputtering process rather than by bonding. These sensors are particularly suitable for OEM applications because of their high robustness and long-term stability. Piezoresistive sensors use semiconductor materials to change the resistance caused by external force stretching and compression. This method, also known as strain gauge technology, provides high accuracy in the measurement range from 0 ... 0.5 N to 0 ... 10,000 kN. The hydraulic pressure sensor works using the piston as the diaphragm as the sensor.
