Fast and Accurate Sensor Film Maps Surface Pressure Distribution for Leading Load Cell Manufacturer
Pressurex® Ideal for Quality Control and Machine Component Inspection
Madison, NJ (USA) - May 22, 2008 - Pressurex®, a thin flexible film from Sensor Products Inc., is a versatile NDT tool for quality control and machine component inspection. Its ability to easily and rapidly show inconsistencies in surface pressure between mating or contacting surfaces has lowered scrap rate and assisted in the design and manufacture of many industrial and electronic products.
Recently Futek, a leading US manufacturer and supplier of load cells, torque and pressure sensors, experienced difficulty assembling some of their load cells to their specifications. By performing several tests, and controlling for different variables, they found fluctuations in clamping pressure to be a significant factor.
Futek's sensors incorporate metal foil strain gauge technology. The adhesive they use to bond the gauges to their sensors requires a clamping pressure of 50-75 psi. However, by using Pressurex®, James Meiselbach, a Mechanical Engineer at Futek, was able to see that the pressure fluctuated from 50 psi to upwards of 200 psi in some of their production runs. This discovery led Futek to use Pressurex® to help redesign several of their clamps to incorporate silicone die springs to regulate the pressure more precisely. "A sample pack of Pressurex® with film that revealed different surface pressure ranges allowed our production to continue," said Meiselbach.
Pressurex® reveals surface pressure from 2 - 43,200 psi (0.14 - 3,000 kg/cm2). No training or instrumentation is required. It is ideal to assess surface contact inconsistencies in virtually any industrial or electronic application, including gaskets, clamps, bolted joints, connectors, heat sinks, heat sealing elements, welding heads, and plastic and composite manufacture, among others.
