BEI Sensors (www.beisensors.com) has unveiled a space-saving and ultra rugged industrial encoder that meets the required standards and certifications for use in potentially explosive environments. Model HS52 is the industry’s first ATEX and UL rated explosion proof hollow shaft encoder.
This rotary encoder can be operated directly in Zone 1 and Division 1 work environments where ignitable concentrations of flammable liquids vapors or gases are likely to exist in normal operating conditions.
The reliable and rugged rotary encoder eliminates the need for an accompanying Intrinsic Safety barrier, effectively simplifying installation. This also results to a more streamlined feedback system for the explosion proof environments.
Utilizing the explosion proof construction method, the HS52 rotary encoder is fitted in an enclosure that has the capability to contain and withstand even the most volatile gas-to-air mixture internal explosion.
The rotary encoder is equipped with a flexible shaft bore design, allowing it to be rigidly mounted to prevent stress to encoder bearings. The design also provides a more secure attachment to the hazardous area conduit fittings.
In addition, the encoder’s compact hollow shaft design provides engineers space-saving advantages not otherwise found in traditional shafted encoders. As ideal position sensing solution for oil and gas industries, the HS52 is also suitable for use in spray painting applications, solvent refining operations and other explosive environments where operating conditions are extreme and space is a premium.
