Connecting a motor, lvdt and load cell to ADC 16

Post by david nulty » Tue Sep 30, 2003 11:27 am

i am looking to connect dc LVDT, load cell and 4kw motor to ADC 16 and i have no idea how to start.

i hope to be able to see the speed of the motor on screen then when a load is applied the load cell through the adc 16 will show the load and the change in speed. the lvdt is to show movement


any thought and ideas would be really greatful:

thanks!!! :)

Hi,

To connect the load cell and the LDVT to the ADC-16 you will have to use a signal conditioner. The ADC-16 can take a voltage of ±2.5 volts and can sample at 1.5 Hz. The main problem that you may face is calculating the rpm. Unfortunately, I am unable to assist in this matter, but perhaps someone else on the forum can point you in the correct direction.

Best regards,
Regards,
