E4N

MICROPROCESSOR COLUMN DISPLAY UNIT

Microprocessor column designed to display dimensional and geometrical measurements, in either static or dynamic elaboration.
The measurement value is displayed:

  • in an analog way on the three-colour LED bargraph scale, showing the measurement status (green=good; red=scrap; yellow=prescrap).
  • in a digital way on the eight-digit display; in this second case the measurement can be comparative or absolute.
Measuring unit, tolerance limits, range, resolution can also be displayed.

It can be configured according to specific application needs, employing different transducer modules provided with 1, 2 or 4 input channels.
These modules can be either:
  • Full-bridge (LVDT), half-bridge(HBT) with 1, 2 or 4 inputs.
  • MRT (Marposs Resistance Transducer) with 1, 2 or 4 inputs.
  • AIR, pneumo-electronic converter with 1 input. When supplied with this module, the E4N can easily and conveniently retrofit and upgrade a wide variety of air gauging applications. The converter card is perfectly interchangeable with the other modules (LVDT, HBT, MRT).
The E4N features a wide range of interfaces:
  • Digimatic and analog to send data to statistical printers or data collectors.
  • RS232-C to send data to PC or standard printers.
  • Relay/BCD to provide a signal for alarms, resume lamps etc.
  • Connector to interface external push-buttons or foot-switches.
It can be programmed via local keypad or PC (by means of the specific E4N-PC LINK software, which also allows data collection).
