Nomenclature of linear displacement sensors

The function of linear displacement sensor is to convert linear mechanical displacement into electrical signal. In order to achieve this effect, the variable resistance slide is usually fixed on the fixed part of the sensor, and different resistance values are measured by the displacement of the slide on the slide. The sensor rail is connected […]

The skill of choosing suitable load cell

1、 Selection of sensitivity Generally, within the linear range of the controller, the higher the expected sensitivity is, the higher the expected sensitivity is. Because only when the sensitivity is high, the output signal value matched with the measured value is relatively large, which is conducive to signal analysis. However, when the sensitivity is high, […]
