Explosion-proof encoder for offshore applications

April 2018 IS & Ex

Many applications in the oil and gas industry that require the use of absolute encoders are demanding, not just from a performance perspective, but also because of the operating environment. An example of this is where the encoder needs to be explosion-proof due to the dangerous atmosphere in which it operates. Another would be applications that involve harsh environmental influences such as offshore platforms where shock loads of over 100 Gs, or shaft loads of hundreds of Newtons, can be experienced. The Hengstler AX65 absolute encoder has been engineered to deal with all these requirements.

Certified explosion-proof, the Hengstler AX65 is built with marine-grade stainless steel and has a shock rating of 200 Gs, and shaft load of 300 N. This tough encoder is not only compact, but it also offers an exceptionally shallow depth and body diameter of only 59 mm. This means it can be installed in applications where other larger explosion-proof encoders cannot be used.

Carrying explosion-proof certification makes it ideal for offshore oil platforms, mines and chemical plants and, as well as other applications that require an encoder constructed from marine grade stainless steel. The shaft load rating eliminates the need for load modules, thus reducing costs.

This device can be installed quickly and easily due to its flexible, quick-connect terminal system. It comes standard with the choice of SSI or CANopen interface, and it is also possible to integrate the CANopen encoder in a ring network configuration.
