Buyer’s Guide on Submersible Position Sensors

In various industrial and mechanical applications, robust sensors are required to produce accurate measurement while performing under extreme conditions. Sensors submerged continuously in fluid should not only be waterproof but must also have environmental sealing for protection against hazardous chemicals. The internal mechanism of a sensor determines the accuracy of measurement; hence when the internal device is exposed to wear and tear, the sensor will break down and need replacement.

Positek’s submersible positions sensors

A submersible position sensor needs resilient fabrication to withstand extreme water pressure. Positek’s submersible sensors are manufactured from marine grade 316 stainless steel. They are far superior to a submersible linear transducer and potentiometer. You can use Positek’s submersible sensors for all types of marine applications including oil drilling and tidal generation systems. Because they are more resilient and robust than conventional waterproof sensors, submersible linear position sensor technology made by Positek is the leading choice among industries.

Choosing a submersible position sensor from Positek

You can select a submersible position sensor from Positek by using the following parameters:

• Measurement type. Position sensors measure different kinds of displacement. There are linear, rotary, and tilt position sensors. An example of a rotary position sensor is Cylinder Position Sensors.

• Measurement range. The range of measurement is another determining factor in characterising a sensor. A linear position sensor often measures in millimetres or inches, while angle and rotary sensors measure rotation in degrees.

• Intrinsic safety requirement. Intrinsic safety is a vital requirement in working conditions exposed to hazardous chemicals that may induce explosions. Intrinsic safety requirement varies by location. In the EU, sensors need to have ATEX certification. For the rest of the world, the standard specification of intrinsic safety certification is IECEx. Another certification requirement is CSA.

• Hazardous environment. Positek’s line of submersible position sensors lends well even when exposed to dangerous working environments like gas, vapour, dust, and mining.

• Environmental sealing. Submersible sensors have IP67, IP68 (10bar) and IP68 (350bar) environmental sealing.

IP68 (350bar) submersible sensors are designed for strenuous conditions exposed to an extreme water pressure of up to 5000psi.

What environments are Positek’s submersible sensors suited for?

Submersible sensors manufactured by Positek can produce continuous, accurate readings even when submerged underwater and exposed to pressures of up to 5000psi. Underwater working conditions can be extremely damaging to a conventional linear transducer, but Positek’s sensors are built to last. All of Positek’s sensors are manufactured using their patented contactless technology. This technology allows for a robust fabrication where internal sensor mechanisms remain frictionless, thus, enhancing durability and resistance to wear and tear.

Does Positek Customise submersible sensors?

Positek is among the few manufacturers offering customisation to customers. We understand that while we have an extensive range in our current inventory, some applications may require specifications that we don’t readily have available. As such, if you are looking for customised options, contact our team of engineers today to collaborate on the design.

All customised sensors are produced in our dedicated onsite facility ensuring excellent quality and speed of production. Positek will require at least two days to manufacture a tailored submersible sensor due in part to the stringent qualifications of the working condition.
