Daily maintenance of hopper scale

1、 Electronic hopper scale weighing process:

The instrument panel controls the feeding machine and equipment to feed into the metrological verification silo or the lifting machine gate opening and closing machine → metrological verification and total net weight: once the silo is opened for feeding, the gate valve is opened for feeding, and once the feeding is completed, the feeding valve is fully automatically closed.

2、 The basic principles for troubleshooting electronic hopper scales are:

1. First mechanical, then electrical;

2. First instrument, then others;

3. Connect the wires first, then transfer the salt. Due to the simple structure of the electronic hopper scale, when a malfunction cannot be identified, the cause can be found by observation, substitution, wire pulling, tapping, and physical instrument inspection.

1. The weighing data is unstable.

This mainly refers to circuit A malfunction, poor contact, poor or damaged cable contact, water ingress into the junction box, and grounding of the instrument casing.

2. The weighing data is incorrect, either too large or too small.

Whether the mechanical installation and limit parts touch. There is an angle difference (with repeatability), which can be caused by the foundation being empty. The sensor runs at zero point and outputs+2mV or 0mV without load. There are angular differences (non repeatability), installation torque/foundation sinking, and sensor sensitivity output issues (strain gauges being damp).

The above is the daily maintenance and troubleshooting information of the electronic hopper scale, specific products. Price related information can be inquired by phone.
