Description

  • Capacity: 50kg
  • Wheatstone bridge sensor
  • Plugs into the Phidgets PhidgetBridge Wheatstone Bridge Sensor Interface (w/ Enclosure)
  • RoHS compliant

The 50 Kg Button Load Cell is used in applications that require a thin form factor. The bottom of the load cell is bolted, and force applied to the button on the top. By loading only the button, which is slightly rounded, the load cell is less sensitive to errors resulting from the load not pushing down exactly straight on the load cell. The electrical signal output by the load cell is very small and requires specialized amplification. Fortunately, the Phidgets PhidgetBridge Wheatstone Bridge Sensor Interface will perform all the amplification and measurement of the electrical output.

Note: No calibration data is included with the sensor. To calibrate the sensor, you need to load the unit down with a few known weights. Then perform linear regression on the data points to obtain a functionrelating output mV/V and applied force.
