Submersible Position Sensors

Positek supplies a range of high-accuracy position sensors specifically designed for use in submersible applications

Manufactured from marine grade 316 stainless, with sealing up to IP68 350 bar (3500MSW), and offering superior reliability over alternative technologies such as submersible lvdt, rvdt or potentiometer, our underwater sensors are used in a wide variety of marine applications such as oil exploration, UAV, water flow gates and tidal generation systems.

With a far greater life expectancy to a waterproof potentiometer and no change in performance over time the Positek submersible range is the first choice in sensing technologies.

The submersible range includes Linear, Rotary and Tilt models all available sealed to 350bar, 5000psi (3500MSW). We also offer a range of 10bar submersible linear sensors for less demanding applications.

As with every position sensor that we supply, our submersible position sensor solutions employ non-contact technology to ensure the highest levels of reliability, even when underwater. Every submersible sensor within our range therefore operates without  wear to the sensing parts, and boasts an extremely low failure rate.

RIPS® S520 Large Angle, Waterproof, Submersible Rotary Sensor TIPS® S623 Large Angle, Waterproof, Submersible Tilt Sensor

Positek Ltd. is a UK based company with over 25 years of experience in manufacturing transducers such as linear position, rotary position, tilt angle, and custom position sensors as well as safe sensors, isolation amplifiers, and submersible position sensors. The company makes use of their own patented technology, the Positek Inductive Position Sensor Technology (PIPS) that has three main categories: the linear inductive position sensor (LIPS), the rotary inductive position sensor (RIPS) and the tilt inductive position sensor (TIPS).

How accurate are Positek's Submersible Position Sensors?

Positek’s submersible position sensors are more accurate when compared to the other alternatives such as the submersible linear differential transformer (LVDT), rotary variable differential transformer (RVDT), or potentiometer. The accuracy of these devices is limited due to friction which also contributes to the deterioration of your sensor.These alternatives make use of three coils, as opposed to Positek’s patented technology which makes use of a high frequency coil which uses less coil turns than an LVDT.

Their submersible sensors also make use of a non-contact technology which prevents wear and tear on the sensing technology.

They are also made of marine grade 316 stainless steel, which seals up to IP68 350 bar (3500MSW). This ensures that the product is durable enough to withstand harsh environments without compromising the sensing technology.

What kind of environments are Positek's Submersible Position Sensors suited for?

The Positek’s submersible position sensors are suited for a variety of environments. They also have a options for light or heavy duty work, depending on what you need for your project. Positek’s submersible position sensors have been used in marine oil exploration, unmanned aerial vehicles (UAVs), water flow gates, and tidal generation systems.

The submersible sensor has a range that includes linear, rotary, and tilt models that are sealed up to 350 bar, 5000psi (3500 MSW). There is also a 10 bar range for light jobs/applications.

Is it possible to have a custom Submersible Position Sensor made?

Yes, it is possible to have a custom submersible position sensor made. Just like Positek’s linear position sensor and cylinder position sensor, their submersible models have a custom design option. Their customisation focus on scaling the position sensor, however other kinds of changes can be made as well..

For the customisation to be carried out, you may contact them via their communication channels and discuss the modifications you want to have done, with their team of engineers. All the sensors are made in an onsite facility and this ensures the quality of the product and faster turn around, Positek suggest that it will take a minimum of 2 days for a custom sensor to be produced.

Submersible sensors require more stringent designs and materials considering the kind of environment they have to work in. There are more variables that could affect the reading and reliability is not just about the initial use, but also how long the accurate reading will last.

Unlike many submersible sensor manufacturers, Positek has the flexibility to customise any submersible position sensor to fit your required size or specification. If our standard range is not suited to your application, please contact a member of our design team to discuss your requirements. We can then have your marine sensor assembled and dispatched in as little as 1-2 working days.
