Digital Column Display Unit


The Marposs E4N Column Display Unit provides a simple, intuitive and fast indication of the measurement. Because of the exceptional visibility of the measurement result, even at significant distances, this product represents the ideal solution for use in production facilities, and provides excellent value for the money. The E4N unit is also compatible with the entire range of Marposs measuring devices, including air controlled systems, which means it is suitable for a large variety of applications. 

Digital Column Display Unit

The E4N Column is used to display the results of static and dynamic shape and dimensional checks, acquired using measuring gauges or cells. It provides the operator with information regarding the measurement values, the tolerance limits, scale, resolution and measurement status. The information can be displayed in analogue format on a 3 color LED bar graph, or digitally on an 8 digit display. In the latter case, the measurement can be comparative or absolute, and the device is capable of memorizing the last measurement cycle, irrespective of the display format.

E4N is available with a wide range of interfaces, which can be used to transmit the data to data collection devices, Personal Computers, or control alarms, indicator lamps etc. via a series of relays. The device may also be connected to a machine tool PLC in order send feedback regarding the checks that have been performed.

The Column may also be programmed via a Personal Computer, which can be used to collect the data.
