By sensing motor current, brushless servo technology can measure motor current to an accuracy of about 10%. This equates to torque measurement in a rotary servo motor and force in a linear servo actuator.  When your application requires higher accuracy, Exlar offers load cell technology embedded in the GSX30, 40 & 50 and I 30 & 40 actuators.  The load cell is a strain gauge type, offering you stable and accurate load sensing in both the tension and compression directions, and for static or dynamic loads +/- 1%. The packaging of the strain gauges are integral to the actuators housing offering a compact, protected, and robust design.

Applications that utilize load sensing include but are not limited to:

Fastening and Joining |  Riveting |  Bag Sealing |  Thermoforming |  Injection Molding | Precision Pressing |  Fillers |  Formers |  Precision Grinders |  Clamping |  Die Cutters |  Lifts |  Molding |  Welding |  Tube Bending |  Stamping |  Test Stands |  Tension Control | Wire Winding |  Parts Clamping |  Dispensers |  Interference Detection
