Unique Tactile Pressure Indicating Sensor Film Aids Circuit Breaker Production

Madison, NJ (USA) - February 19, 2008 -- Sensor Products Inc. presents Pressurex®, a tactile pressure indicating sensor film that quickly and accurately maps and measures pressure distribution and magnitude between any mating or contacting surfaces.

Recently a major manufacturer of circuit breakers searched for a mechanical method of checking contact alignment and surface pressure of a series of moving contacts that mated to a stationary contact bar.

They used Pressurex® to see whether each contact was making at least a 70% mating of contact surfaces. If it was found to be less than 70%, the manufacturer made a series of adjustments to correct the alignment, each time verifying the markings the contacts made on the Pressurex® film. The manufacturer said they knew of no other product that could let them see markings of the individual pressure distribution of the contacts so that they could manually assemble the circuits. Pressurex® is now being used as part of their quality control protocol.

Pressurex® film measures pressure from 2 - 43,200 PSI (0.14 - 3,000 kg/cm2) and is available in seven pressure ranges. When placed between two contacting or mating surfaces, it instantaneously and permanently changes color. This color change is directly proportional to the actual pressure applied. Precise pressure magnitude is easily determined by comparing the resultant color intensity to a color correlation chart (conceptually similar to interpreting Litmus paper). No training or instrumentation is required.

Pressurex® is ideal for dozens of electronic and industrial applications, such as assessing contact inconsistencies in heat sinks, gaskets, clamps, connector, bolted joints, heat sealing elements, nip rolls and welding heads.

It is also a useful tool for analyzing contact uniformity in the design and production of printed circuit boards (PCB) assemblies. In wafer fabrication, Pressurex® is often used to verify flatness, revealing lamination press problems caused by inconsistent bonding pressures. It can successfully predict and evaluate load distribution, revealing problems such as the overloading of connector contacts, standoffs, and component solder joints.

New uses for Pressurex® are discovered daily. For a free sample of Pressurex®, contact Sensor Products Inc. at 1.973.884.1755 (USA), email them at info@sensorprod.com, or visit their website at sensorprod.com/sample.
