Submersible Linear Sensors: High-Accuracy Solutions for Harsh Environments

Introduction to Submersible Linear Sensors

Positek’s portfolio includes a range of high-accuracy linear sensors specifically designed for use in submersible applications. Made from marine-grade stainless steel and offering reliability beyond what is possible from a submersible LVDT or linear potentiometer, our sensors have served various industries, including wastewater and offshore oil drilling.

Advantages of Submersible Linear Sensors

Superior Alternative to Waterproof Linear Potentiometers

Our submersible linear sensors are not only capable of withstanding submersion in depths of up to 3500m but are also suitable for any harsh environment where the sensor might be exposed to excessive amounts of freshwater or other non-corrosive liquids but are also suitable for harsh environments where the sensor might be exposed to excessive amounts of salt water due to the 316 stainless steel construction. This versatility makes them a superior alternative to waterproof linear potentiometers.

Non-Contact Technology for Enhanced Reliability

All our submersible position sensor solutions employ non-contact inductive technology to ensure the highest levels of reliability, even underwater. Sensors can even be calibrated at the factory underwater to provide the best accuracy possible.

Customizable to Fit Your Needs

Unlike many submersible LVDT manufacturers, Positek offers the flexibility to customize a submersible position sensor to fit your required size or specifications. Each series is built to the millimeter required. That said, some applications will require even more customization and that isn’t a problem. Whether for a small project or an OEM application, housings, sealings and other components can be modified to provide the ideal sensor for your application, while maintaining short lead times, typically 4 weeks or less depending on expedite options. 

Depths and Environments for Submersible Linear Sensors

Built for Deep Waters

A submersible sensor is built to work in deep waters. Our linear position sensors are durable enough to tolerate pressures of depths up to 3,500m, and some models can endure even deeper waters while still providing high-precision measurements.

Resistant to Extreme Conditions

Our submersible sensors can withstand deep-sea conditions with pressures up to 5,000 psi. They are built to endure a wide range of environmental stressors, from temperature to high levels of shock and vibration. For hazardous environments where explosive atmospheres are possible, the sensors are available with formal CSA, ATEx and Intrinsically Safe ratings with the use of an galvanically isolated amplifier barrier.

Uses for Submersible Linear Sensors

Applications in Harsh Environments

Submersible sensors are commonly used in applications submerged in relatively clean water, but they can also be found in lift stations, underwater oil mining, wet wells, holding tanks, refineries, filling equipment, and distillation processes. Common applications also include water measurement in vessels, reservoirs, pits, and channels. The use of 316 stainless steel makes them appropriate for food and beverage processing.

Crucial Component in Modern Machinery

Sensors are now essential in a wide range of machinery and equipment across various applications. In vehicles, sensors monitor engine performance and ensure safety features function correctly. In consumer gadgets, they enable functionalities like touchscreens and motion detection. In large-scale machinery, such as underwater vessels and ships, sensors provide critical data for navigation and system monitoring. Every industry, from automotive to marine, benefits significantly from the precision and reliability of sensors.
