HEIDENHAIN ND 2100G GAGE-CHEK

Digital Readouts for Multipoint Inspection Equipment

nd2100g 

The ND 2100G GAGE-CHEK readouts are versatile metrology displays for measuring and inspection tasks in manufacturing and quality assurance. With inputs for up to eight encoders, they are designed for multipoint measurements from simple pass/fail detection up to complex SPC evaluation.

Design

The ND 2100G GAGE-CHEK digital readouts have a large colour graphic screen and are housed in a robust, diecast aluminium enclosure.

Functions

The inputs can be assigned and combined as desired with mathematical, trigonometric or statistical formulas. This makes it possible to measure even complex dimensions such as thickness, flatness, volume and more. The results are displayed numerically or graphically as a colour bar graph or a dial, or archived for statistical process control (SPC). The GAGE-CHEK can be configured for basic or advanced applications. Soft keys and function keys can be adapted as required. The Min/Max function of the ND 2100G readouts monitors and stores the highest and lowest measured or calculated value. Warning and tolerance limits can be assigned to each display value. Results outside of the tolerance are marked with a different colour. An acoustic alarm sounds simultaneously. Tolerance values, SPC parameters and custom formulas are stored for individual parts. GAGE-CHEK can manage up to 100 parts, each with up to 16 visible measurement features and 16 hidden measurement features. The rapid acquisition of measurement data allows for monitoring of dynamic events, such as the eccentricity of a rotating shaft.

Data Interfaces

The GAGE-CHEK features various interfaces for communicating with parent systems. The RS-232-C/V.24 serial interface enables communication with a PC and also remote control.

Bar diagram

You can select to have the values shown as a colour-enhanced vertical or horizontal bar graph. The defined warning limits and tolerance limits provide instant feedback. If these limits are exceeded, the column colour changes from green to yellow or red, informing you explicitly of critical dimensions.

SPC and data storage

nd2100g)spc

GAGE-CHEK includes integrated SPC studies such as mean value charts (X bar) and range charts (R). Min, max, sigma, cp and cpk are also calculated, and are clearly displayed as a graph or histogram. Historical raw data can be saved in a tabular numeric display. Each dimension and all data are time and date stamped.

Formulas and combinations

nd2100g_formula

You can use mathematical and trigonometric formulas, as well as logical conditions, to combine individual measured values or measurement sequences with each other, and so create complex calculations. This can be used, for example, to calculate and display the circumference of a turned part, the volume of a cube, or the angle between two cams, and also to assign tolerance limits to these values.
