Mahr Inc. (Providence, RI) has expanded its OPTIMAR 100, a solution for testing dial and digital indicators, test indicators and dial comparators, with image processing for the automated testing of measuring equipment. According to Mahr, a new upgrade kit makes working with the measuring instrument safer and faster: a camera automatically records the indicated values of the test indicators and forwards them to a software for processing. The automated procedure saves time and eliminates potentially error-prone readings by the operator.
The hardware and software add-on package provides a cost-efficient way to equip existing measuring stations with OPTIMAR 100 for automated testing. The measuring system, including image processing, is also available as a package under the name Precimar OPTIMAR 100 BV.
The upgrade kit incorporates a USB 3.0 camera for fast image processing, and stable daylight-independent LED illumination along with secure digital identification and reading of digits. The 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 makes it possible to create and store test certificates.
With the auto-recognition of the vision system, more test items and data points can be recorded faster than with conventional manual methods, according to Mahr.
