Application

Das Gerät ist durch die Klartextprogrammierung in Verbindung mit einem LCD-Display an viele Anforderungen sehr einfach anpassbar. Durch die mögliche Eingabe von 25 Stützpunkten ist das Gerät auch ideal zur Volumenberechnung z.B. von liegenden zylindrischen Behältern.

The digital display and evaluation device is conceived for the evaluation and conversion of a analogue input signal into a standarized output signal of 0-10 V, 0-20 mA or 4-20 mA with up to 4 relay switching points. Due to the plain text programming in combination with a LCD display the device can be easily adapted to many applications. Due to the possible input of 25 linearization points the device can linearly calculate also nonlinear input signals (e.g. from lying cylindrical container).

Function

At the input of the digital display and evaluation device there can be also connected sensors with a supply voltage of 5V DC and an output signal of 0,5 tu 4,5V DC as well as analogue signals 0...10V, 0...20mA and 4...20mA with a supply voltage of 24V DC.

The measurement signal can be adjusted in a wide range and is converted into a output signal of 0...10V, 0...20mA, 4...20mA, 10...0V, 20...0mA or 20...4mA.

0/2/4 relay switching contacts with a respective separately adjustable hysteresis can be assigned to the input signal.

Due to the implemented signal linearization (max. 25 control values) it is possible to linearize the output signal, e.g. for volume calculation of a conical or cylindrical lying container.

The output signal can be influenced by an integration time of up to 30 seconds, e.g. to suppress signal fluctuations due to mixing machines or at a filling process. 

The display and evaluation device has implemented a tendency evaluation that can be switched on two relays.

The device has also a minimum and maximum value storage that is additionally displayed in the analogue bargraph as tow pointer.

All functions and settings can be set by plain-text programming using the LCD display and the keyboard.
