Inner Diameter Hole Measurement Probe Now Wi-Fi Enabled

Riftek’s RF609 series is capable of wireless measurement of borehole diameter, for precision geometric measurement and inspection of small inner diameter holes By Phoebe Grinter / 17 Jun 2021

Riftek, with full support from its exclusive UK and Ireland distribution partner Ixthus Instrumentation, has released the RF609 series laser triangulation probes, adding a Wi-Fi interface to the device to facilitate wireless measurement of borehole diameter specifically designed for precision geometric measurement and inspection of small inner diameter holes.

The new RF609 Wi-Fi is a rechargeable battery-powered device supplied as a complete system with mains charger, cables, PC software and a detailed operation manual. 

Developed for use as part of a CNC machine’s automatic tool changing system, these ultra-compact measurement probes measure the distance to the hole surface as the probe is rotated and moved axially into the hole; synchronously measuring the polar surface coordinates which are interpreted through PC software to build a 3D geometric model pattern with micron level accuracy.

The device is available in two measurement versions allowing a range of inner diameter measurements to be made: 9 to 19 mm or 16 to 48 mm diameter with maximum bore length of 139 and 143 mm respectively. 

Both probes feature the 48 mm diameter main controller, battery and Wi-Fi housing with an extended shaft that houses the laser triangulation sensor scanning head. A 16 mm diameter shaft facilitates straightforward collet mounting on the CNC.

Set-up procedure includes software download and initial wired USB connection to interface the probe followed by a simple probe calibration routine that sets the probe rotation speed, calibration diameter and tolerance parameters.

The RF609 series is also available as a self-powered device with a built-in slip ring assembly for power input and data signal output. The compact probe head has been proven in special custom-made equipment developed by Riftek for specific component measurement – sometimes used in conjunction with linear and rotary translation positioners to allow for scanning pipes, bushes, stepped and tapered holes and tubes etc. 

This principle has also been applied to special debris inspection equipment for small diameter holes where traditional vision systems can be troublesome.
