Werth Messtechnik Sensor heads mounted to tilting, rotating joints can measure in any position

Editor: Eric Culp

The IP 40 T and IP 110 T sensor heads from Werth Messtechnik GmbH can be adapted to tilting and rotating-tilting joints to enable flexible measurement in image processing applications, even with large coordinate measuring machines (CMMs).

Fully integrated in the Werth multisensor concept, the compact sensor heads have telecentric optics and an integrated zoom function. Their noncontact measurement principle is based on Werth contour image processing with high-precision autofocus, which allows standard geometric elements to be measured and contours to be scanned.

The IP 40 T is available with magnification of 4X or 1.5X and a working distance of 40 mm. It provides brilliant image quality when using darkfield incident light and thus is useful in measuring low-contrast technical plastic parts. Owing to its short length, very little of the measurement envelope is lost when it is pivoted and parked.

The IP 110 T, featuring 1.5X magnification at 110 mm of distance, is well suited for measuring lower-lying features without risk of collision.

Both measurement heads can be used with the Renishaw PH10M rotating-pivoting joint, or on the Werth pivot joint, directly on the ram of the CMM. A powerful brightfield incident-lighting system is integrated in the beam path. The darkfield incident-light illumination option, implemented in an eight-segment ring, provides optimal contrast. This light ring can be exchanged for the Werth Fiber Probe to create a rotary-tilt measurement head with a microprobe that allows high-precision contact measurement of extremely small geometries with only slight contact forces.
