No-Drift Absolute Gauging Package

New absolute-length gauge plus metrology display panel

The Heidenhain Acanto with EnDat 2.2 combines the advantages of an optical encoder with an absolute length gauge.

Heidenhain Corporation has coupled its new Acanto absolute length gauge with the established and versatile ND 2100G Gage-Chek metrology readouts to create an effective combination for many fixed gauging applications.

Heidenhain is the North American subsidiary of Dr. Johannes Heidenhain GmbH, a manufacturer of precision measurement and control equipment. Its products include linear scales, rotary and angular encoders, digital readouts, digital length gauges, CNC controls, and machine inspection equipment.

The Heidenhain Acanto absolute length gauge with EnDat 2.2 provides the benefits of an optical encoder and solves many of the problems of different length gauges. Quality managers will not have to worry about their gauges drifting, linearity over the entire measuring range, or referencing upon startup.

The Acanto's measuring principle is the measurement standard and does not drift over time, nor does it require mastering. "Sweet spots" are nonexistent with the Acanto as 2 µm of accuracy are held throughout the entire measuring length. The new absolute technology, using EnDat 2.2, enables the Acanto to know its position upon power up with no need to reference. The Acanto is available in spring-operated and pneumatically operated models and is offered in 12 mm and 30 mm measuring lengths.

The Heidenhain ND 2100G Gage-Chek will handle gauging and inspection tasks from simple pass/fail detection up to complex logic statements communicating to a PLC. They can be configured for basic or advanced operations where inputs can be assigned and combined as desired, along with mathematical, trigonometric or statistical formulas. This makes it possible to measure even complex dimensions such as thickness, flatness, volume and more. Rapid acquisition of measurement data can monitor dynamic events such as the eccentricity of a rotating shaft.

The Heidenhain ND 2100G Gage-Chek has a new, color LED-lit read-out that will display results numerically or graphically as a bar graph or dial indicator. The ND 2100G Gage-Chek can manage up to 100 parts, each with up to 16 visible measurement features and 16 hidden ones and can save thousands of data entry points for internal statistical process control (SPC) or export. User customization is easy with programmable soft and hot keys. Min/Max functions monitor and store data, and warning and tolerance limits can be set to each display value.

A new plug-and-play routine allows for effortless interfacing of the Acanto and ND 2100G Gage-Chek. The ND 2100G Gage-Chek can interface with one to 8 Acanto gauges and will be an effective solution for many gauging applications. The ND 2100G Gage-Chek will also accept any EnDat 2.2 encoders from Heidenhain including linear, rotary, and angle.
