Load cells and tube straightening

THAMES SIDE-SENSORS GOES STRAIGHT

Tube straightening machines made by The Bronx Engineering Co Ltd are achieving high accuracy results with help from Thames Side Sensors load cells.   To ensure precise straightening, shear beam load cells have been custom-made to measure loads of up to 12,500 Kg to an accuracy of 1 Kg.   These slim-line devices form an integral part of the machines, which are specified throughout the world for straightening tubes with diameters between 1.5 mm and 660 mm.

Bronx machines have six driven rollers arranged in pairs, each top roller being disposed at opposite angles to its partner below.   Until recently, due to space constraints, the force applied to each tube was measured using a load cell some way from the rollers at the top of the machine.   This required careful compensation for the weight of the roller support assembly beneath.   However, the slim-line design of the Thames Side Sensors cells means that they can fit immediately above the top roller of each pair, so are not influenced by the weight of the machine.

Kelvin Lane, Chief Designer at Bronx Engineering, explained his reasons for choosing the load cells:

"We just specified the space in which the load cells were required to fit and left Thames Side to produce an accurate shallow-profile solution.   Their digital meter slotted easily into our instrument panel and we were impressed with the simple calibration procedure required to zero the cells before each use."
