Camera Speeds Testing of Dial, Digital Indicators

Mahr Inc. has expanded its Opitmar 100 solution for testing dial and digital indicators, test indicators and dial comparators with image processing to automate the testing of measuring equipment. 

Mahr Inc. has expanded its Optimar 100 solution for testing dial and digital indicators, test indicators and dial comparators with image processing to automate the testing of measuring equipment. An upgrade kit with a camera automatically records the values of the test indicators and forwards them to software for processing, increasing the system’s safety and speed. The automated procedure saves time and replaces operator readings, which are prone to errors. 

The hardware and software add-on package equips existing measuring stations with Optimar 100 for automated testing. The measuring system, including image processing, is also available as a complete package called the Precimar Optimar 100 BV.

The upgrade kit incorporates a USB 3.0 camera for fast image processing. Stable, daylight-independent LED illumination, and secure digital identification and reading of digits. QMSoft software controls the measuring device, evaluates the camera image of the scale or number display of the test object, compares the values with the high-accuracy internal reference scale and automatically completes the process of calibrating the product under test. The software also enables users to create and store test certificates.

The solution is designed to be easy-to-use, so operators can quickly monitor the indicators under test. The vision system’s auto-recognition enables users to record more test items and data points faster than conventional, manual methods. Because the inspection system is automated, users can complete other operations while the system automatically completes the calibration process.
