Digital
Pressure Gauge LED is a microprocessor based unit which can operate with
an internal resolution of 40,000 div. Max. (full scale can be presetted in
accord with each application).
In order to increase the
integration level of the components, a combined traditional and SMT technology has been applied. This results in a pressure gauge more
resistant against mechanical stresses and vibrations besides ensuring
maximum reliability of the electronic circuit.
This instruments results are very versatile thanks to the possibility
to transmit any data through the RS232C output connected to a computer
or an intelligent peripheral. Two digital SET POINTS are available
with power relay and analog output, which can be:
In voltage 0 - 5 Volt or 0 - 10 Volt
In current 4 - 20 mA |
 |
|
For very dynamic applications, to increase resulting stability, digital
pressure gauge is equipped with a very programmable digital filter
(first or third order with programmable time constant - very flexible). |
