Ultrasonic probe   

The ultrasonic probe, available into the toolbox, must be placed on a tank, it can measure the height of liquid or the free height in the tank.

How to configure a ultrasonic probe :

From measurement to the electrical value and to the automaton acquisition

The user must set the values :

• the physical limits of the measurement or of the set point value (e.g. from 5 cm to 300 cm , from 0 % to 100 % for a set point value) ;

• the standard type of acquisition card (from 0V to 10 V, From -10V to +10 V, from 4mA to 20mA) ;

• the behaviour of the sensor : linear or non linear ;

• the measure type

• free height,

• height of liquid,

• the limits of the acquisition card of the automaton (limits of the word processed by the automaton) ;

• the fields of mnemonic and of description are not absolutely required.

1. An info-bubble shown in the RUN mode gives the following information separated by a comma :

1. physical quantity ;

2. electrical value ;

3. automaton data value.
