X117 Linear Position Sensor

Description

Positek X117 Slim-line Linear Position Sensor is intrinsically safe. ATEX and IECEx approved for use in potentially explosive gas/vapour atmospheres. The X117 Slim-line Linear Position Sensor is designed for industrial and scientific feedback applications and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The ATEX unit is very compact and space-efficient with a small 19mm diameter body. The sensor is very robust, the body and push rod being made of stainless steel. The sensor is easy to install with mounting options including M5 male stud and M5 rod eye bearing. The push rod can be supplied free or captive, with male M5 thread or M5 rod eye. Like all Positek sensors, the X117 provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-5mm to 0-350mm and with full EMC protection built in. The X117 offers a range of mechanical options, environmental sealing is to IP67.

All of Positek’s position sensors are manufactured to the highest quality and use our very own patented non-contact technology. This helps to ensure the highest levels of accuracy and reliability, even in the harshest of environments. Every position sensor that Positek manufactures uses their inductive sensor technology to ensure high-precision results, and is fully customisable to meet the unique requirements of your business.

With over 25 years’ experience as a sensor manufacturer and using our onsite production facility, Positek has the flexibility to manufacture and customise any industrial position sensor, including tilt sensors and inclinometers, to any size or specification.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:

Measurement Range

Factory set to any length from 0-5mm to 0-800mm in increments of 1mm. For example, if your application requires 10" (254 mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 254 mm.

Intrinsic Safety

ATEX/IECEx approval

The sensor is ATEX/IECEx approved to:
Ex II 1G
Ex ia IIC T4 GA (Ta = -40°C to +80°C).
This 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 sensor surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to 80°C.
Approval only applies to the specified ambient temperature range and atmospheric conditions in the range 0.80 to 1.10 Bar, oxygen <=21%.

Galvanic Isolation Amplifier

Intrinsically safe sensors must be used with a galvanically isolated amplifier with safety parameters not exceeding:- Ui: 11.4V, Ii: 0.2A, Pi: 0.51W. Sensor can be installed with a cable length up to 1000m maximum from the amplifier, cable capacitance and inductance can be up to:- Capacitance: 200 nF max, Inductance: 810 μH max.

Approved amplifiers are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.
