Before leaving the factory, the electronic crane scale will be calibrated in advance, and can be used directly on hanging. If there is a hanging scale to lift up the weight of the display to zero, and then weigh out all the weight is its net weight, relatively simple loadometer and other electronic scales, so the installation of the operating procedures is the process of lifting goods.
Hopper scale directly show electronic crane scale with a period of time is not accurate how to do?
Methods: According to the principle of superposition comparison type dynamometer, the force value generated by the jack was transmitted to the calibrated standard sensor and the calibrated hopper scale sensor simultaneously through the mechanical frame. The weight shown on the weighing meter accompanying the standard sensor is the weight loaded by the sensor used to calibrate the hopper scale.
Hopper scale weighing sensor and PLC how to connect?
Weighing sensor can adopt two different input and output connection methods: one is six-wire connection, the other is four-wire connection.
1, the hopper scale four-wire system of the weighing sensor has no special requirements for the secondary instrument, it is more convenient to use, but when the cable is long, it is easy to be affected by environmental temperature fluctuations and other factors.
2. The weighing sensor of the six-wire system of hopper scale requires that the secondary instrument used together with it has a feedback input interface. The range of use has certain limitations, but it is not easy to be affected by environmental temperature fluctuations and other factors, so it has certain advantages in precision measurement and long-distance measurement.
