General measuring equipment GME III General description Input / Output The General Measuring Equipment III (GME III) is a flexible and powerful tool that can be used for various dimension measuring applications by using inductive probes or analogue inputs with temperature compensation for Statistical Process Control and Post Process Control with interface to Siemens PLC System (e.g. S7-1200). The system is the successor of the GME I, GEM II and GME II+ which has an installed base of 1 500 units. A Siemens PLC can be connected to the measurement box over the LAN. The Siemens controller has full control of the measurement jobs in automatic mode. Depending on the used Siemens controller different number of digital inputs and outputs can be used to fully control the measurement process. Without Siemens controller the on-board digital I/Os can be used to trigger measurement jobs or sort the measuring part. The onboard digital inputs can be configured for basic control of a measurement process. The onboard digital outputs can signal different results of a measurement. For simple controller applications the internal digital I/Os can be used. Transducer input For half bridge (e.g. Tesa GT21/22) and full bridge (e.g. Mahr 1301) inductive probes different measurement boxes exist. Analogue transducers are also supported as general temperature transducers. User Interface Closed loop control The optional graphical user interface simplifies operator interaction with the GME III. The software needs a PC with Microsoft Windows installed (7, or newer). Full keyboard control is standard. The GME III can be safeguarded from unauthorised use by means of password protection, with different levels of authorisation. With the self tuning control system compensation pulses can be sent automatically to a production machine for closed loop control. Measurement calculation The GME III supports static and dynamic measurement modes. A formula parser allows advanced measuring parameter calculation. More than one input can be used simultaneously for calculating a parameter. The measurements can be compensated automatically for temperature differences by using a temperature sensor via analogue input. Statistics Statistical process control detects automatically out of control conditions in accordance with the SKF QT1 and Ford AIAG standards. The GME III allows eight simultaneous control charts. Typical evaluation screen 2 Export of measuring parameter Measurement data can be exported via QDAS transfer format to QSSTAT or to Excel format (CSV). Mechanical mounting The GME III Basic may be mounted on a 19” rack, a wall or simply set on the desk top. The measuring box of Starter kit should be mounted together with a PC (Mini PC) into an electrical cabinet or as close as possible to the transducer inputs. The GME III Touch version can be used for manual application as standalone version.
