Encoder with high pressure option increases application scope

Already partnering with a number of global component manufacturers, Heason has announced one of its distribution partners, Zettlex, has recently added a high pressure option to its comprehensive range of durable inductive angle encoders - which in turn expands the application potential for positioners and actuators for use in subsea, oil and gas and industrial high pressure process environments.

Zettlex´s IncOder inductive encoder technology is well proven and has a long list of successful installations for high temperature/humidity, high vibration/shock and other extreme environments where individual angle, position, speed or complete servo feedback, is essential.

Throughout the IncOder´s Mini, Midi and Maxi series - which span nominal diameter sizes from 37-595mm - a wide choice of options allow a great deal of installation flexibility. Users can choose angular resolutions from 10 to 22 bits, or any whole-number of pulses/rev. Supply voltage options cover 5, 12 and 24VDC whilst mechanical interfacing for the two-part rotor/stator angle encoder includes shaft mount, servo clamp, external mount and more.

This wide choice is further enhanced with output and communications interfaces that cover, but are not limited, to Synchronous Serial Interface (SSI), analogue voltage (+/- 10V), A/B/Z pulses and BISS. The large internal diameter, which is inherent to the IncOder design, also allows through-hole access for wiring, air/hydraulics and other services. All these features make the angle encoder a great choice for many other positioning applications, not just for extreme environments.

For operation at high pressures, for example in deep-sea equipment such as submersible vehicles or remotely operated valves for subsea oil and gas fields, users can now specify an extended range product option that shifts the recommended pressure range up to 280 bar (4,000 psi). This extended range combines with the already high levels of resilience to all types of extreme conditions that the IncOder can accommodate. For Heason, this option will mean that servo feedback for precision actuators and positioning systems that are used in arduous application conditions will not be limited for such high pressures environments.

Heason Technology integrates other harsh environment components into such positioning systems. Highly durable components from other key distribution partners include KBM submersible servomotors from Kollmorgen and Elmo Motion´s ExtrIQ range of severe environment drives and motion controls.

As an example of an application that could benefit from the extended range Zettlex IncOders, Heason has recently completed the supply of a precision rotary actuator that accurately positions and powers the rudder and hydroplanes on a scaled submersible ROV vehicle. This was developed for hydrodynamic design evaluation studies for military submarines. The extended pressure range could be specified as part of the servo control, if perhaps the customer required the ROV to perform at higher pressures and lower working depths.

In addition to its non-contact inductive IncOders, Zettlex also designs and manufacturers a range of non-contact linear encoders for position and speed feedback applications in extreme environments. Heason Technology supports the full Zettlex range with individual component supply or as essential parts of complete motion sub-systems.
