Description
Position sensors X520
Rotary inductive position sensor
X520
As a leading designer and manufacturer of linear, rotary, tilt and intrinsically safe position sensors, we have the expertise to
supply a sensor to suit a wide variety of applications. Our X520 RIPS (Rotary Inductive Position Sensor) incorporates electronics
system EX07 which is ATEX / IECEx approved for use in potentially explosive gas/vapour atmospheres. The X520 is designed to
provide feedback for arduous underwater applications, such as ROVs, where hazardous surface conditions may exist. The X520,
like all similar sensors, is supplied with the output calibrated to the angle required by the customer, between 15 and 160
degrees and with full EMC protection built in. The sensor provides a linear output proportional with input shaft rotation. There is
a machined registration mark to identify the calibrated mid point. 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.

Specifications (continued)
Intrinsically safe equipment is defined as “equipment which is incapable of releasing sufficient electrical or thermal energy
under normal or abnormal conditions to cause ignition of a specific hazardous atmosphere mixture in its most easily ignited
concentration.”
ATEX / IECEx approved to;
Ex II 1G
Ex ia IIC T4 Ga (Ta = -40°C to +80°C)
Designates the sensor as belonging to; Group II: suitable for all areas
except mining,
Category 1 G: can be used in areas with
continuous, long or frequent periods of exposure to hazardous gas (Zone 0).
Protection class ia, denotes intrinsically safe for all zones
Apparatus group IIC: suitable for IIA to IIC explosive gas.
Temperature class T4: maximum surface temperature under fault conditions 135°C.
Ambient temperature range extended to -40°C to +80°C.
It is imperative intrinsically safe sensors be used in conjunction with a galvanic barrier to meet the requirements of the product
certification. The X005 Galvanic Isolation Amplifier is purpose made for this range making it the perfect choice. Refer to the
X005 datasheet for product specification and output configuration options.
Safety Parameters:
Ui: 11.4V, Ii: 0.20A, Pi: 0.51W
Ci = 1.36µF* Li = 860µH* (with cable)
Ci = 1.16µF Li = 50µH (without cable)
*Figures for 1km cable where: Ci = 200pF/m & Li = 810nH/m
Sensors can be installed with a maximum of 1000m of cable.
Cable characteristics must not exceed:
Capacitance:
≤
200 pF/m for max. total of: 200 nF.
Inductance:
≤
810 nH/m for max. total of: 810 µH
For cable lengths exceeding 10 metres a five wire connection is recommended to eliminate errors introduced by cable resistance
and associated temperature coefficients. ATEX / IECEx approved sensors suitable for dust (E series) and mining (M series)
applications, are also available.
