In an age when manufactured components are heading into the realm of the micro and even nano scale, quality assurance is becoming challenging. Werth Inc. (Old Saybrook, CT), a supplier of dimensional measurement technology instruments and optics, has a new solution. The Werth Fiber Probe (WFP) has opened up the world of microstructures for tactile coordinate metrology.

Low contact forces of less than one millinewton and small probe spheres down to 20 microns in diameter make the 3D WFP suitable for use on precision-engineered components and on sensitive surfaces.

This capability previously was available only with straight probe pins, said the company. The L-probes now available can measure undercuts, small side bores and even internal threads.

The L-probes have sphere diameters from 0.040 to 0.250 mm. The standard offset between the probe sphere and shaft is about 1.5mm; other offsets are also available.

With modular control and software integration, the new Werth Fiber Probe can be used in scanning or single-point mode. To take advantage of the precision of the sensor, it is recommended for use with high-precision machines, such as the VideoCheck UA, and with a 3D maximum permissible error down to 300 nanometers.
