Pressurex is a useful metrology tool in assessing compressive magnitude and distribution between contacting or impacting surfaces.
Applications exist in both machine/component inspection and calibration.
Pressure Points are a valuable aid in machine calibration and unit pressure distribution between components of machine assemblies such as teeth of gears, frames, shafts, gasket and flanges, clutch and brake plates, glue and adhesive jigs, welding heads, and electronic component packaging.
Other applications are as diverse as ultrasonic welding, explosive forming, indication of uniformity during composite materials fabrication, determination of effective placement of strain gauges, determining drawing pressure in dies, package drop test pressure, and measuring the interface pressure in mechanically attached joints.
In general, any application involving stress between two surfaces can benefit from Pressure Point's capabilities.
Each Pressure Point sensor film comes pre-packaged in a ready-to-use blister sealed pouch.
Pressure Points are available in sizes ranging from 8 cm to 2.5 cm diameter.
The pouch has a clear window on one side for viewing the pressure film and a pressure sensitive adhesive on the back enabling the sensor to be quickly and easily affixed to any surface.
The user simply places the Pressure Point sensor at a specific location of an interface.
When force is applied, the sensor film instantaneously and permanently changes color.
The intensity of this color is proportional to the amount of force applied, allowing the user to actually quantify the stress characteristics across the contacting surface.
Precise kg/cm2 can be determined by comparison of the Pressure Point to a colour calibration chart (conceptually similar to interpreting Litmus paper), or by using one of several imaging systems that Sensor Products supplies.
