Heidenhain has coupled its new Acanto absolute length gage with its ND 2100G Gage-Chek metrology readouts to create a package for fixed gaging applications.
The Acanto Absolute Length Gage with EnDat 2.2 provides the benefits of an optical encoder while solving the problems associated with differing-length gages, the company says. The measuring principle is the measurement standard, and it does not drift over time or require mastering, the company says. Additionally, the package holds accuracy of 2 µm throughout the entire measuring length, eliminating “sweet spots.” Absolute technology, using EnDat 2.2, enables the device to know its position at power-up without referencing. Both spring-operated and pneumatic versions are available in 12-mm and 30-mm measuring lengths.
The ND 2100G Gage-Chek readout is said to simplify gaging and inspection tasks ranging from simple pass/fail detection to complex logic statements communicating to a PLC. Inputs can be assigned and combined as desired, along with mathematical, trigonometric or statistical formulas. According to the company, this enables measuring such complex dimensions as thickness, flatness, volume and more. Moreover, rapid acquisition of measurement data enables monitoring dynamic events, such as the eccentricity of a rotating shaft.
Results can be displayed numerically or graphically as a bar graph or dial indicator. The readout can manage as many as 100 parts, each with as many as 16 visible measurement features and 16 hidden features, and it can save thousands of data-entry points for internal statistical process control (SPC) or export, the company says. Programmable soft and hot keys enable easy customization. Min/Max functions monitor and store data, and warning and tolerance limits can be set to each display value.
The ND 2100G Gage-Chek can easily interface with 1 to 8 Acanto gages via a plug-and-play routine, the company says. It will accept any of the company’s EnDat 2.2 encoders, including linear, rotary and angle models.
