We have a problem with a weight meter (Milltronics BW500 Integrator 7MH71522BA052AA) installed on a critical conveyor belt, the integrator is a new piece of equipment installed today, the load cells (2 Units) are 50 Lbs and the speed sensor ( Sitrans WS300 / 256 PPR from the Siemens brand) both equipment was assembled the day before yesterday, being new as well, the calibration was carried out with standard weights (2 Units of 8.16 Kg) with the following data:

P002 (Reference test selection) :1 (Weight)

P003 (Number of load cells) : 2

P004 (Flow measurement system) : 2 (Metric)

P005 (Reference flow unit) : 1 (T/h)

P011 (Reference flow) :15 T/h

P014 (Reference speed) : 0.273 m/s

P015 (speed constant) : 203.7183

P690-01 (Program Speed ​​System) : 2 (Sensor Data)

P691-01 (Stage 1: Drive pulley diameter) : 400 mm

P692-01 (Stage 2: Pulses/Revolutions) : 256 (Speed sensor / WS300 data)

P016 (Band length) : 60.30 m

P017 (MS1 test weight) :13.495 Kg/m ( 16.194 / 1.2)

P018 (Speed ​​regulation) : 0.273 m/s

P940-01 (Cell A mV signal check) : 8.12 mV

P940-02 (Cell B mv signal check) :10.11 mv

P952 (Reference load) : 15.45 Kg/m

The calibration was carried out with the Zero and Span keys, yielding an approximate load value of 13,495 Kg/m (Similar to parameter P017), at the time of material entry into the belt (it has a certain % of water) the milltronics bw500 integrator It indicates a flow greater than 30 T/h and an approximate load. According to a belt cut made days before, the belt should be passing approximately 7 T/h, having a very large error of more than 23 T/h. flow difference, also mention that several rollers on the belt were changed, including those on the scale, and that mechanical personnel aligned the belt. This BW500 integrator that was changed is a more updated version of the ones previously available, being the first time that we have had this type of problem with the weight meter since new equipment has previously been placed in other belts being in normal operating conditions with the aforementioned procedure. calibration.
