BroadWeigh bring testing and calibration expertise in-house
1 April 2015BroadWeigh manufacturer Mantracourt has developed and manufactured a new in-house testing and calibration machine to test the accuracy of its wireless load monitoring systems.
According to the manufacturer, the BroadWeigh system offers "real-time, simple, effective and accurate" load monitoring for rigging professionals, safety officials and site managers and enables them to monitor and log the precise loads on any given rigging point.
Kelly Voysey, marketing manager at Mantracourt, explains: "Each BroadWeigh shackle is now calibrated using our new test machine, The calibration software developed by our engineering team communicates directly with the shackle and the test rig to record the shackle's calibration. The software then generates a calibration certificate.
"The new automated calibration technology will help us meet the increasing demand for our BroadWeigh system, whilst helping us ensure its accuracy and reliability in the field. In this respect, it has been an important achievement, as we look to build on our success going forward."
In using the new test installation, each shackle is calibrated and linearised over eight weight points covering its operating range while each weight is applied and allowed to settle, and then the calibration and linearisation parameters are calculated and applied to the shackle.
According to Mantracourt, once all points have been calibrated, the shackle is unloaded then loaded again at four points over its operating range to ensure that it falls within in-house specification. The calibration record is electronically stored for future recall, and a calibration certificate is issued showing the results of the four-point calibration check.
The company's in-house calibration machine has a capacity of calibrating up to 10 tonnes and the main rig load cell is calibrated against an NPL approved transfer standard load cell.
