Development and production of preselection counters/displays

Preset counters/displays are indicators designed to count various types of pulses, from both analogue and digital signals, to then display them. For this purpose, the counters/displays are able to convert different physical quantities into electrical impulses to be displayed, so as to allow the reading of data that offers an understandable indication of the quantity to be measured.

Once upon a time, this would have meant electromechanical devices but technological evolution has led to a whole range of electronic meters and displays, today equipped with microprocessors and being user programmable.

Operation

To perform its functions, the meters/displays must be able to read both analogue and digital signals. For this reason, they are equipped with various inputs with scaled voltage, by a potentiometer, both in direct and alternating current, or even by logic signal inputs.  With this equipment, these devices can acquire signals such as pulses, times and frequencies from any kind of industrial sensor, from photocells to incremental encoders, to optical scales, along with linear transducers, proximity switches and electric limit switches.

Values can then be assigned to the pulses measured by an encoder or sensors on the mechanical parts, so as to adapt the count to the actual quantities to be measured and permit the signals to be read correctly.

Applications

There are thus a multitude of applications of meters/displays, in combination with analogue or digital transducers. These devices are used wherever it is necessary to count and display length or thickness measurements, or even the number of machined pieces; they are used in the same way for dosages, predeterminations, plus batch and displacement controls, both linear and angular. They can work as pulse counters or frequency meters.
The industries and processes in which they are employed are therefore extremely different and include:

• Default cuts or machining
• Dosing and packaging operations
• Windings
• Paper industry
• Engineering industry
• Iron and steel industry
• Chemical and pharmaceutical industry
• Food industry

Custom models

ELAP develops and manufactures customised preselection meters/displays, designed for counting and displaying specific customer industrial processes, along with as a series of widely-used standard models. Thanks to the extremely vast possibility of configuration and calibration of our instruments and to our internal design studio, ELAP products can be tailored to any specific need you may have.
