Exlar offers select models of its GSX and I Series actuators with integral force measuring capability. This option is avail- able in the GSX30, 40, 50 & 60 models and the I30 and 40 models.In both product lines a load cell is embedded within the actua- tor allowing it to directly mea- sure the force being applied by the actuators output rod. The strain gauge load sensor used to measure applied force is mounted inside the actuatorҒs case, protecting it from exter- nal damage and guaranteeing accurate and consistent force data.A separate connector is sup-plied for connecting the internal load cell to an external strain conditioner/amplifi er required to excite the strain gauge sen- sor. Alternatively, Exlar can offer strain gauge conditioners to provide a high level output signal, either 0-10V or 4-20mA.Alternatively, any one of nu-merous conditioners/amplifi ers available can be used for this purpose. > Strain Gauge Amplifi er GSX Series Linear Actuator ?

strain gauge signal conditioner must be selected, ordered, in- stalled and calibrated.What seems on the front end to be a simple implementation of a force measuring system fre- quently turns into a project requir- ing expertise from both electrical and mechanical personnel. It is also common to see such projects extend beyond the target comple- tion date as system components are redesigned or reordered.Exlars embedded force measur-ing option eliminates much of the effort and the risk associated with measuring the applied force produced by the actuator.

Strain Gauge Function ? The strain gauge acts as a resistor in one leg of a Wheat- stone bridge ? The strain gauge amplifi er ap- plies voltage across the bridge at A-A (excitation voltage), causing current to fl ow through the bridge ? The resistance of the strain gauge changes as a function of the force being applied ? The output voltage across B-B changes as a function of the force being applied to the load cell. Typical Features ? DIN rail panel ? 24 Volt power ? +/- Volt or 0/4-20 mA output ? Simple gain & offset adjust- ments ? Auto calibration ? Simple fi ltering options ? With or without...
