ONM expansion probe. 40-200 mm application range, max. expansion distance 20 mm

Application

For measuring grooves and recess diameters by inserting the probe through a larger opening. Please note the maximum retraction or expansion area. If you have any questions, please send us a drawing or sketch with details of the larger opening, measuring depth and recess diameter with tolerance and recess width (B)

Execution

• Supplied without basic unit/holder, please refer to article number 33576010
• ONM expansion probe with carbide-tipped wedge needle, without fixed measuring contact (callipers); the required measuring contacts (callipers) are available on request and start at 20 mm, increasing in increments of 5 mm as standard, up to 55 mm (ONM 20-55); or starting at 40 mm, increasing in increments of 5 mm as standard, up to 200 mm (ONM 40-200/10 and ONM 40-200/20).

Advantage

• Rapid measurement of groove/recess diameters in bores
• High measuring pressure ensures reliable measurement
• Especially suitable for series measurement

Notes

IMPORTANT: The measuring instrument will not work without the basic unit (33576010) and the measuring contact (ONM only). A dial gauge/precision pointer and an adjustment tool are also required.

We recommend including a drawing/sketch with your request
