About the X520 Rotary Inductive Position Sensor

The intrinsically safe 350 bar X520 rotary sensor is ATEX and IECEx approved for use in potentially explosive gas/vapor atmospheres. The X520 is an affordable, durable, high-accuracy rotary sensor designed for Marine and Subsea feedback applications.

The X520 is supplied with the output calibrated to the angle required between 15 and 160 degrees and with full EMC protection built in. The sensor provides a linear output proportional with angle of rotation. There is a machined registration mark to identify the calibrated mid point.

It is particularly suitable for OEMs seeking good sensor performance for arduous applications such as subsea ROVs where long term reliability and excellent sealing is important. Overall performance, repeatability and stability are outstanding over a wide temperature range.

The X520 has long service life and environmental resistance with a rugged 316 stainless steel body and shaft, The flange mounting makes the sensor easy to install. There are a range of electrical options. Environmental sealing is to IP68 350Bar, 3500 msw, 5000 psi.

The intrinsically safe sensors are designed to be used with a galvanically isolated amplifier. Approved galvanic isolation amplifiers are available; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.

As a leading supplier of linear, rotary, tilt and intrinsically safe position sensors, Althen has the expertise to supply a sensor to suit a wide variety of applications.
