The weighing sensor is an important part of belt weigher.With the development of the technoligy,the electronic instruments made of weighing sensor have been widely applied to various industries,especially in the digital weighing sensor realizes the fast and accurate weighing of the materials,especially with the emergence of the microprocessor,the improvement of the degree of automation of industrial production process,the digital weighing sensors have become required devices in the control process,from previous large cans,hopper and other weight measurement which can not weighing,and crane scales,truck scales and other measurement control,to batching system that mix a variety of raw ingredients,automatic detection in the production process and the control of powder feed rate,all these have applied the digital weighing sensors.Currently,digital weighing sensors have applied to almost all of the weighing areas.Then what are the specific advantages of digital weighing sensors?

Firstly,it is convenient and easy to adjust the angular difference of digital weighing sensor.The scale body consists of digital weighing sensor,so the angular difference can be automatically adjusted with the software.The forces of four sensors can be read by the instrument,so it only need to over load at each corner,the instrument can calculate the angular difference coefficients of each point,automatically adjust the angular difference,eliminate the hassle of repeated loading weights,load once to complete the adjustment of angular difference and improve efficiency.Because the signal can not be distinguished,when calibrating the scale body which consists of simulation type weighing sensor,it needs to add weight on each sensor and use the potentiometer in the junction box to adjust angular difference.What's more,because there is interaction among the each sensor,therefore,it requires repeated adjustments.

Secondly,the maintenance cost of the system is low.Although digital weighing sensor increases the circuit board,it reduces the cost of debugging and application in the application,and change the sensor without re-calibration,etc,and the function of self-diagnostics and uninterrupted work of digital weighing sensor improve the system reliability and reduce downtime.Therefore,the overall system cost is lower than simulation type weighing sensor.Because the signal can not be distinguished,the scale body of simulation type weighing sensor,it needs to carry on the partial load error adjustment when replacing sensor,and to add weight on each sensor and use the potentiometer in the junction box to adjust angular difference.Because there is interaction among the each sensor,and the adjacent bearing point will influence each other,it requires to repeat several times.

Finally,the maintenance of digital weighing sensor is convenient.Digital weighing sensor uses military standard 5-core plug,which makes the sensor and cable lines into two separate devices,so it is more convenient to replace the sensor or cable,do not need to wear a cable.Since digital signal is transmitted,the length of cable lines can be changed as required,without affecting the weighing accuracy.When replacing digital weighing sensor,it only needs to input the relevant parameter into the new sensor,without the need for re-calibration of the system.Since simulation type weighing sensor makes temperature compensation together with cable lines at the time of production in order to eliminate the influence of the temperature of the cable resistance.If randomly connecting the cable lines of simulation type weighing sensor after they are damaged,it will cause weighing errors.Therefore,when the distance is long,the sensor will need to be customized.
