Exlar EL100 explosion-proof linear actuators

Exlar’s linear actuator line has been expanded to include the EL100 explosion-proof linear actuators, rated for Class I, Div 1, Groups B, C, D and T3 hazardous environments. The EL100 linear actuators also meet ATEX requirements for use in potentially explosive atmospheres and are in conformity with the EU ATEX Directive 94/9/EC.

The EL Series linear actuators integrate a planetary roller screw mechanism with a high torque servomotor in a single self-contained package. The roller screw consists of multiple threaded rollers assembled in a planetary arrangement around a threaded shaft. This design is claimed to provide reliable and precise operation over thousands of hours, handling heavy loads even under extremely demanding conditions.

Exlar’s EL100 actuators offer speeds up to 63 cm/s, force up to 8.8 kN and stroke length up to 15 cm. They use completely sealed 8-pole brushless motors with windings available from 24 VDC to 460 VAC. Several mounting configurations are available and feedback configurations for nearly any resolver-based servo amplifier.

For process applications, the EL100 can be coupled with Exlar’s EXP Series positioner. High performance is achieved with respect to speed, linearity, load sensitivity, deadband and temperature range. For valve and damper control, the EL Series actuators continuously hold the position of the valve stem or shaft allowing fast response to the smallest command signal changes without overshoot, even when friction is present. This results in improved loop performance and reduced process variability.
