They are predicted for measuring electrical signals of all kind.
The display of the measured magnitude is been done by:

a) digital display b) analog bargraph display c) combination (digital + bargraph)

The devices have a posibility of giving the output signal of the measured magnitude of 0-20 mA or 4-20 mA (measuring converters).
Repressing of the measured magnitude of input signal is from 0 to 500%.
With temperature signals there is a circuit for linearisation built in.


Function description:

1. The display of current measured magnitude is in real measure units such as °C, l/h, mm, t/h, % or other physical measure units.

1.a. The display of Y magnitude on the digital display or bargraph is possible.

2. It is possible to repress the showed magnitude on a display up to 500% areas with current input signals.

3. While measuring with thermo-probe, a compensation of the cold end of thermo-element (temperature stabilisation) has been done, as well as the input for the outer compensation.

3.a. The protection from bursting of the thermoelement and a thermometer resistent to that kind of input were built in.

3.b. A compansation circuit for line resistence with thermoelementary and resistent probes were built in.

4. The possibility of converting the measured magnitude into some of the standard signals, for instance 4-20 mA.

5. The display is made of high-quality integrated components without the parts which tend to tear which gives the device a great reliability and unsensbility to vibrations and interruptions.
