hello everyone ,

I want to test the flow of my project using this sensor , i got the data sheet but i dont really get how it works or how should i connect it .

i want to connect it to an analog input that's read voltage only so what should i do in this case


here you can find the data sheet of the sensor i am using:

I tried to build the circuit in the data sheet but it did not really work out

 

hi kh,
Are you using the analog voltage output signal.
Is the supply voltage 24Vdc.

In what way did it 'not work.?

Exactly which model do you have - what are the letters and numbers following 'FLEX-FIN'?

 

Looking at the data sheet, the voltage output requires a load resistor of 1k ohms. Does this correspond to your set up?

I believe what the data sheet is getting at is:

4..20 mA / Load 500 Ohm max. or 0..10 V / Load min. 1 kOhm

When using a Current output option of 4 - 20 mA the maximum load resistance is 500 Ohms resulting in a 2 to 10 volt drop across the load resistor or for example a 250 Ohm load would result in a 1 to 5 volt drop. The load resistance for a current mode output can not exceed 500 Ohms. When choosing a Voltage output option the load resistance needs to be a minimum of 1 K Ohm to obtain the 0 to 10 volt output, anything less than a 1 K Ohm load will cause excessive loading of the output preventing the analog out voltage from reaching 10 volts. The load resistance for a voltage mode analog output can not be less than 1 K Ohm. That is what I believe they are getting at with the 1 K Ohm.

it worked now thanks a lot
