We work with manufacturers of heavy machinery, vehicles, consumer goods, medical devices and pharmaceuticals, and even aircraft and rocket ship builders. All these industry experts know that precision test and measurement solutions are essential for eliminating the serious threat to humans when their inventions and products are not thoroughly tested and monitored properly.

Testing is the first step in the process of ensuring safety. Interface load cells and torque transducers are used to test a wide variety of parameters related to force. For instance, Interface provides solutions for projects involving the testing of cranes and ensuring that these massive machines are able to lift the weight that the particular product’s specifications allow. This ensures safety for the user and those on the ground by putting the machine through rigorous testing using load cells to measure the cranes maximum limits with various loading conditions. Watch a quick demonstration video of crane safety test solutions from Interface.

In addition, force measurement can be used to measure small and precise forces during the testing phase. One such example is the use of load cell load buttons to measure the clamping force of a vascular clamp used in surgery. This force needs to be tightly tuned in regulation with stringent medical requirements. Forces too small or large could have serious repercussions for the patient. This is a simple test that makes a dramatic difference in which the clamp force is applied to these miniature load cells and the force signal is sent to the tester.

One specific requirement that Interface has a great deal of experience in supplying solutions is for torque testing on lug nuts, bolts and other assembly equipment.
