The Electronic Scale Ruler has become a standard instrument in the Print and Packaging, Security and Offset Printing industries where it's use makes accurate length measurements significantly easier and more reliable. The Electronic Scale is also an indispensable measuring system for the calibration of imagesetters and in the electronics industry.

Available in 7 lengths from 180mm to 1500mm and three different optical systems, the Electronic Scale is supplied with a factory test protocol so integration into your QA system is ensured.

Length measurements are achieved with the an inductive strip mounted on a hardened stainless steel guide which provides the electronics with the precise position of the measuring carriage. The guide runs on longitudinal ball bearings, free of any play and wear. The two lateral positioning slides facilitate quick, parallel alignment of the scale with the item to be measured.

An easy-to-read display with six millimetre high characters shows a maximum resolution of 0.01 millimetres or 0.0005 inches. A fine adjustment is located immediately next to the display. The vertical arresting screw arrests a part of the measuring carriage. Operation is simple with a horizontal positioning screw moving the carriage sensitively to the measuring point. The zero point for the measurement can then be set by pressing the reset button. After moving the carriage to the second measuring point the result can be read off on the display.

Optical System - 3 Variants

The Electronic Scale is supplied in three optical variants: either 10x Magnifer (ES Model), 25x Microscope (ES-25) or 50x Microscope (ES-50). 

10x Magnifier - ES Model

The ES model is supplied with a premium quality 10x Magnifier with a four coated lens optical system,10x magnification factor, making it possible to move precisely to the measuring point. The magnifier can be focussed for adjustment to suit the operator and is equipped with a glass graticule plate for exact positioning of the measuring carriage. The hard chrome vapour-coated graduations on this plate ensure precise readings.
An ingenious parallax control ensures that the viewing angle is perpendicular to the lens. Two lateral positioning slides make parallel alignment of the scale with item being measured simple and quick.

ESM-25 Microscope 25xESM-25 Microscope 25x

25x/50x Microscope - ESM Model

For very fine positioning the ESM version with microscope maybe be used. The Electronic Scale is then supplied with a 25x or 50x microscope instead of the 10x magnifier. 

The ESM microscope version avoids any possibility of parallelism errors (small deviation in readings) that may occur when using the 10x magnifier if the parallax control scale is not used properly by the operator. However, when using ESM version the image is reversed (mirrored) making it less convenient for some operators.

The 25x and 50x microscopes are fitted with a scale with graduations and cross-hairs.

ES-USB CameraES-USB Camera

USB Camera (Optional)

The Electronic Ecale, ES model (10x), can be ordered with a video system for convenient series measurements. Then deviations resulting from parallelism are avoided and the image is not reversed.

The USB Camera enables movement to measuring points using either the graticule plate or the software reference functions such as cross hairs all on a conveniently mounted monitor (not included). Using the USB camera also relieves the operator as they are not bending over to place their eye against the magnifier or microscope.

USB Camera option can only be fitted to the ES model, not the ESM. Existing ES models can also be upgraded with the camera later.

Is the 500 mm length for ES-500-10 the length it can actually measure or is it the outer length of the whole device? In the latter case, what is the maximum distance it can measure?
