Load cell (how to convert V to N)

Click For Summary
SUMMARY

The discussion focuses on converting voltage readings from an Omega load cell with a 150g capacity and a rated output of 2mV/V to force measurements in Newtons. The user reports a no-load voltage of 0.06V and a maximum voltage of 0.7V when applying force. To convert these voltage values to force, the formula used is Force (N) = (Voltage Output / Rated Output) * Capacity. The rated output of 2mV/V indicates that for every volt of excitation, the load cell outputs 2mV per kilogram of load.

PREREQUISITES
  • Understanding of load cell specifications and terminology
  • Basic knowledge of electrical voltage and force conversion
  • Familiarity with the formula for converting voltage to force
  • Experience with using multimeters for voltage measurement
NEXT STEPS
  • Research the formula for converting voltage output from load cells to force measurements
  • Learn about load cell calibration techniques
  • Explore the specifications and documentation for Omega load cells
  • Investigate the use of data acquisition systems for load cell readings
USEFUL FOR

Engineers, technicians, and hobbyists working with load cells, particularly those involved in force measurement and calibration processes.

Hello,
I have Omega made load cell with 150g capacity,Rated output 2mV/V, Excitation 10V.How I can convert voltage values to the force (Newtons)?When no force applied meter shows 0,06V and then i pressing with finger the max value I get is 0.7V.So how I can converts those volts to Newtons now?
