Calibrating a Force Sensor
A force sensor (also called a load cell) is calibrated with a load
standard. It is calibrated such that the maximum compression and
tension represent ±100% of the full-scale capacity of the force sensor,
with zero force set at midcapacity.
Prerequisites Be sure the items described in “Before You Begin” on page 97 are true.
A force sensor requires a Digital Universal Conditioner (DUC)
configured for the DC mode that processes a DC feedback signal. You
must know which conditioner is connected to the sensor.
Initial calibration If you are calibrating a sensor for the first time, you may find it
necessary to:
• Perform an initial tuning of the sensor channel before calibration.
• Perform the procedure twice.
Recalibration If you are recalibrating a sensor, use the existing calibration values as a
starting point.
What you will need You will need the following items to calibrate a a force sensor. All
calibration tools should also be calibrated to an industry standard.
• A load standard can be a calibrated force sensor with its own
electronics or it can be a calibrated set of dead weights.
Note This calibration procedure calibrates the DC conditioner for a force
sensor of ±10 kN. You will need to adjust the procedure to
accommodate your force sensor.
• A DVM to monitor the output of the load standard.
Calibration Types The FlexTest SE controller’s full-range conditioner allows you to
choose Gain/Delta K, Gain/Linearization, mV/V Positive Tension, or
mV/V Positive Compression calibration.
Important note Procedures for “Automated Controllers” assumes the FlexTest SE
Controller is equipped with the PC-Supervision option, and that
Exclusive Control is assigned to Station Manager. For more information
about Station Manager, see the Model 793.00 System Software manual
that accompanies your system.
