Intrinsically Safe Linear Sensors

At Positek we have a full range of Intrinsically safe Linear Sensors

What is an Intrinsically Safe Linear Sensor?


Intrinsically safe sensors and systems are used to provide a safe operating environment for personnel and equipment. They do this by restricting the electrical energy transmitted into a hazardous area.

Intrinsically Safe Sensors are different to explosion-proof sensors. Intrinsically safe sensors are unable to produce a spark strong enough to cause ignition, whereas an explosion-proof sensor would contain an explosion if it were to happen.

Linear sensors are used to measure displacement in a straight line. This is often required in a variety of industries including intrinsically safe environments.

Where are Intrinsically Safe Linear Sensors used?

Our Intrinsically Safe Linear Sensors are suitable for different environments. We have Linear Sensors for Gas/ Vapour environments, areas containing dust, and sensors for mining environments. Intrinsically safe linear sensors are often used in application areas including;

  • Gas Utility Plants
  • Sewage Treatment Plants
  • Oil Rigs
  • Chemical and Pharmaceutical Applications
  • Large Scale Dry-Cleaning Applications

Intrinsically Safe Linear Sensors from Postiek

Our intrinsically safe linear sensors, like all of our sensors, use our very own sensor technology. This technology is similar to that of an LVDT, but with an improved stroke to length ratio and with an internal signal conditioner.

Our sensors are designed for demanding hydraulic or pneumatic cylinder position feedback applications.

Some of the benefits of our sensors are;

  • Long service life
  • Environmental resistance
  • Good value for money
  • High performance
  • Able to withstand wide temperature range

Overall, our sensors are also very compact making them suitable for applications where space is restricted. They are also very rugged and able to withstand harsh environmental conditions.

All of our intrinsically safe linear sensors can be found on the products section of our website – find out more here.
