mA to newton

[Luuk van der Pluijm]

I have the DIGILENT 6069-410-007 web data logger with an top censor and an loadcell. The loadcell is connected to the top censor and then from the mA output to the web data logger. Here I get an graphic, but it is in mA. I need it in Newton becouse it is for an school project and the graphic needs to be instand readable for the students, so it needs to be in Newtons. Is that even posible to do in the data logger, and if so, how?

I hope someone can help me with it, I really cant find it. 

I already tried to connect the loadcell direct to the data logger but then I get a wrong graphic, if I push the loadcell in, nothing changes and it only looks like a 'sawing' motion.

Hello @Luuk van der Pluijm.

What are the make and model #'s of the top sensor and loadcell used with the WebDAQ 904 (p/n 6069-410-007)?  Please provide a link for the datasheets.

Please provide your screen capture.

In the WebDAQ's Job Editor, the default units for a Full Bridge type sensor is mv/V. 

 

However, a user can enter a custom unit in the Units field, i.e. Newtons.  Next, using the sensor's manufacturing sensitivity specification (mV/V) to calculate a loadcell's measurement in pound-force (lbf) or Newtons (N) is handled in the Custom Scaling section using the Multiplier and Offset.  In the screen capture below, the scaling multiplier was calculated by dividing the loadcell's maximum capacity (Newtons) by the sensor's sensitivity specification (mV/V), i.e. 1334 Newtons / 3.016 mV/V.
