FORCE ADAPTER
Sensor Type
A Force Sensor set up comprises two parts, the sensor and the adapter. The adaptor connects a
Flexi force sensors to the encoder. Contact TTL or our authorized dealers for information on
purchasing the sensors.
Operating Principle
A force sensor is sensitive to load applied to a small area of its surface. Force sensors are
available in a number of maximum load ratings for example 10lbs and 50lbs. When connected to
a person or object they sense changes in the applied pressure. The sensor plugs into the
adapter which in turn plugs into the encoder.
Measurement Unit
A force sensor converts the load applied to a raw value, as the load changes the value
corresponding to that load changes with it. This raw value can be transformed into a meaningful
calibrated value in the software by using the linear transform virtual channel. This linear
transform takes the minimum and maximum raw value and converts it to the min-max output
values corresponding to the positions (e.g. -119 to 72 becomes 0 to 10lbs).
To calibrate the sensors, connect the hardware and open the Force calibration screen then start a
recording. Apply a know load to the force sensor and record the loaded (max) and unloaded
(min). Stop the session and move to the channel set that is going to be used to record data, edit
the virtual channel set and select the virtual channel relating to the sensor that you are
calibrating. Manually enter the input Min and Max values and the corresponding output min and
max values of the known load. It is also possible to enter the units of measure which will appear
in generated reports.
