Displays, totalizers and batch controllers

Digital displays present the value on a display, in the form of a number or via a graduated scale made up of LEDs that light up progressively, simulating the analogue display.

These instruments are divided into two categories, differentiated by the type of input signal they receive which can be pulsed or current.
Pulse digital displays receive the pulse signal and display the measurement in the engineering unit of interest.
These indicators are mainly applied with liter meters.

Digital current indicators, on the other hand, convert an analogue 4÷20mA or voltage 0÷10V input signal into an engineering unit, which is then shown on the display.

Typical applications of these digital indicators are the display of signals coming from transmitters which can be temperature, humidity, pressure, speed, flow rate, level, force, etc. for the most varied industrial sectors, operating machines, automation.

Digital Proportioners not only show the measurement, but can also generate a start-stop signal for controlling valves or other instruments.
Some of them allow you to set alarm thresholds, so that when the value exceeds these thresholds, digital outputs are activated to signal and control the event.
Other digital proportioners are equipped with analogue outputs which, through electrical signals, can be connected to a recording instrument to store the signal.
