Swap out Renishaw probe styles to inspect different features on a part without having to recalibrate. These probes mount magnetically to a base that threads into your coordinate measuring machine (CMM), making mid-inspection changes quick. They’re also known as modules. It’s easy to tell different styles apart from their different end colors. To take 3D measurements, they record the coordinates of different points on your workpiece. Because this involves physically touching your workpiece, they’re more accurate than other automated measurement systems. They’re touch-trigger probes, the most common CMM probe type, which means they stop to record the coordinates of one point at a time. Use them to check distances, diameters, right angles, and the location of holes and grooves. However, they're not as good at checking complex features, flatness, or roundness.

All probes require a stylus as well as a base (sold separately for some probes).

Trigger force is the amount of force required for a probe to take a measurement and record it. Choose a probe with a force that is high enough to avoid false triggers from vibration but not so high it damages the workpiece and leads to inaccurate measurements.

Probe and Base Kits

SF Series—SF series probes have a trigger force that works for most general purpose probing jobs where vibration is not an issue.

TP20 Series—TP20 probe bases have a magnetic proximity switch to prevent a probe from accidentally triggering when you’re attaching it or detaching it. However, probes attached to these bases can’t be used to inspect magnetic parts.

Probe Bases

Bases house the system that sends a signal to record a measurement. They thread onto probe heads with an M8 connection on your CMM.

TP20 NI Series—TP20 NI probe bases aren’t affected by magnetic fields, so they can be used to inspect magnetic parts. However, because they don’t have a magnetic proximity switch, you’ll need to program your CMM to stop taking measurements when you’re changing out probes.

Modular Scanning Coordinate Measurement Machine Probes

Determine a part’s precise shape, position, and size—these Renishaw probes give you comprehensive 3D measurements by continuously gathering data as they move across your part. This means that unlike touch-trigger probes, they can follow the shape of complex features, such as angles and curves. And because they collect more data points than touch-trigger probes, they’re better for engine cylinder bores, dies, and other components that require high accuracy to fit into other parts. These probes are more accurate than other automated measurement systems that use light or cameras instead of touch.

To inspect different features, you can swap them out for a different probe without having to recalibrate. They mount magnetically to a base that threads into your coordinate measuring machine (CMM), making mid-inspection changes quick. They’re also known as modules.

All probes require a stylus, a stylus holder, and a base. Choose a probe based on how long your stylus needs to be. These probes are highly sensitive to length, so you should make sure that the combined length of your holder and stylus falls within the probe’s effective working length range. If you want to use the same probe with multiple styli, you can use multiple holders. However, you can’t mix and match probes with different stylus holders.

Probe and base kits give you a basic setup that’s suitable for most measuring applications.
