eyes.gif·Can anyone tell me if there is a website that shows how to connect a 0-10 bar pressure transducer to a BS2P40. The sensor is a danfoss MBS5150, input 10 - 32 vdc.Output 4-20mA. Im trying to get the reading in Bar on a parallel LCD. All help more than welcome

Thanks

    Dear Alan,

    To convert the 4-20mA, you can put a precision resistor 250 ohm 0.1% in series with the input current.
    It will convert the 4-20mA into 1 to 5 VDC.
    From here you can supply the voltage to a analogue to digital converter(ADC) example ADC0831 to get the digital signal to supply to BS2.

    regards.
