Inmoco is extending the capabilities of its high torque, long life Exlar GSX and I ranges of electric linear actuators, with the introduction of an integral force measuring capability; a load cell embedded within the actuator. This option offers a direct method for obtaining electronic data relating to the force being applied by the actuator. Moreover, the packaging the of the load cell delivers a compact, protected robust design, with the strain gauge load sensors embedded within the actuator housing.
The integrated load cell option is available on Exlar’s GSX30, 40 and 50 models, and the I series 30 and 40 model actuators. The load cell is a strain gauge type, offering stable and accurate load sensing (+/- 1% linearity, +/- 0.5% repeatability and hysteresis, 1% nominal) in both tension and compression directions, and for static or dynamic loads.
The force measuring option is provided as a package, which includes a separate fitting for connecting the internal load sensor to an external strain conditioner/amplifier required to excite the strain gauge sensor. In addition, Exlar offers a rugged strain gauge conditioner to provide a high level signal, either 0 - 10V or 4-20mA output, for monitoring of the output signal - which, importantly, is compatible with standard gauge monitors and PLC strain gauge input cards Alternatively, any one of numerous conditioners/amplifiers on the market can be used.
The GSX and I series actuators on which the force measuring option is available both employ Exlar’s roller screw technology. For the last 15-years, this has been the integral component in creating the most reliable, long lasting electromechanical actuators on the market, providing a long-life, all-electric replacement for hydraulic cylinders in thousands of applications.
The GSX actuators also benefit from Exlar’s T-LAM technology, a new, segmented lamination stator design that enables 35% more continuous motor torque to be provided from the same frame sizes as competitive actuators, with no cost premium.  
The brushless servo design of the GSX series linear actuators allows them to be used in state-of-the art closed loop servo systems, where electronic control of positioning and velocity is required.
The robustness, precision and reliability of the GSX and I series actuators mean that they are suitable for use in many demanding applications including, fastening and joining
riveting, bag sealing, thermoforming, injection moulding, precision pressing, clamping, tension control, welding, tube bending, wire winding, dispensing, testing, filling – and many more.
