Some minor issues with the weight sensors used in belt scales.
Thread Content
For the belt scale weight sensors used in the coal feeder, we use a pair of them – one is installed on each side of the belt. They are from Saimo and are of the 4-wire type. Input 10V, output is 0.2 mV/V. My question is, what voltage should be adjusted to, in a few millivolts, at the time of installation? Because it needs to be balanced on both sides; one end is fixed while the other is suspended. Is there a specified value for this adjusted voltage?
There are no specific regulations; it is better for both sides to be adjusted to match. The belt scale needs to be calibrated before use, and it can be used accurately only after the calibration is successful.
The belt scale poses problems; moreover, the working environment is extremely dirty
Aren’t nuclear scales popular these days? Can the accuracy of the belt scale be guaranteed?
I’m using around 10V here; I should ask the manufacturer for the exact value. Voltage refers to the installation gap. As long as the zero-time slot is appropriate, using a code to set it to zero should suffice.
