PA8110A weighing

2016-02-27View Original

Thread Content

Our factory uses PA8110A weighing displays. After replacing the sensor, the displayed values started to increase automatically, even though there isn’t much material in the scale. What could be the reason? If anyone knows, please let me know. . For example, if it is currently 520 KG and then becomes 520.7 KG, it means the value after the decimal point has increased. . . . .

His value keeps rising – what’s the reason for that?

Check the millivolt signal at the junction box to see if the values of the four terminals are all the same.

Are you using the weighing system from Yuyao Pacific? Explosion-proof?

The scale needs to be calibrated after replacing the sensor; I’m not sure if that has been done.

Finally, I’ve waited for you – is it input or output? One connector accepts 4 wires and one shield wire. . . Can I add you on QQ? My 79466989

It needs to be calibrated; it starts to expand as soon as the material is inserted inside

It’s explosion-proof. In the junction box, is it Brann or yellow-red that is measured? There are three sensors in total, one of them is empty, and it seems there’s also a variable resistor on it. . . . .

The resistance of the sensor varies depending on the manufacturer; it’s approximately 350 ohms (this is the case for Toridou). It needs to be measured. Potentiometers have nothing to do with automatic scaling; they are used for fine-tuning. It’s impossible to determine exactly why it grows automatically; try resetting it to zero. I don’t think this kind of slight increase is anything to worry about; if the growth rate is fast, then it’s likely that the base plate is damaged. It’s also possible that a wire isn’t connected properly; the shielding must be pressed firmly in place.
