Measuring bore diameter

The DIATEST BMD bore gauge precisely measures the internal diameter of a rivet hole

Extremely simple to use, maximum accuracy and absolute measurement reliability

• Measures the absolute value immediately
• Easy to use, requires minimal training
• Holes from Ø 2.0 mm up to 270 mm
• Static and dynamic measurement
• Detection of dimensional deviations and shape defects,
• Repeatability up to 1 µm
• High linearity
• Extremely long service life
• Customised solutions

Guarantee of the highest measurement accuracy:

• Zero setting is carried out at the factory or using an optional DIN 2250-C setting ring

Types of application for bore gauges:

• Manual measurement, directly on the aircraft or on a machine
• Automatic in-process measurement on a CNC machine, using a robot or in a measuring fixture

Dial gauges and digital displays.

Depending on the requirements, various dial gauges and displays are used with a BMD:

• Digital DIATRON1500-S: network-compatible wireless measuring system with display and a resolution of 0.1 µm – particularly suitable for tight tolerances!
• Digital dial gauges, with a resolution of up to 0.001 mm, e.g. the MDU-A125
• Mechanical dial gauges
• Transducers / Probes
• DIATRON6060-µNetwork measuring computer
• DIATRON2200 measuring column
