Product Description

The plug gauge measurement system (BMD) is a high-precision measuring instrument with automatic display and automatic centering functions. This plug gauge measurement system is easy to use and suitable for both static and dynamic measurements. By manual measurement, the size deviation and shape error of the hole can be detected, and it can also be installed on measuring equipment for automatic detection.

This measurement system has the advantages of wide application range, simple operation, high accuracy, and sturdy structure. There are many basic models to choose from in standard products, and accessories that meet specific measurement ranges are provided to ensure that most apertures encountered in practical applications can be measured. The display part of the measuring instrument can be a mechanical meter, a digital display meter, or a sensor connected to the analysis equipment. Use a calibration ring gauge for zero calibration.


Product Features

Quickly measure aperture, roundness, and ellipticity
Especially suitable for manual and automatic measurement of high tolerance grade parts produced in large quantities
Automatic centering, no need to search for inflection points inside the hole during measurement
Ideal choice for reading and subsequent analysis of measurement results using a digital display meter
The measuring head consists of a hard chrome plated cylindrical guide body and carbon steel measuring points
The carbon steel measuring needle transfers the radial movement distance of the measuring point 1:1 to the display table
The built-in elastomer provides continuous force measurement, thus eliminating human factors
The measuring instrument is a modular system consisting of a measuring head, handle, depth extension rod, limit block, and right angle attachment, with a wide range of applications
