A Buyers Guide to Linear Position Sensors


Linear position sensing technology has undergone massive developments in the last few decades. The use of new materials and the development of new engineering techniques allowed a more versatile application for sensors. These days, a linear position sensor can be applied in situations where it is exposed to highly corrosive compounds as well as extreme temperatures. Nonetheless, the durability of new materials lend well in these conditions.

Positek’s linear position sensors can be applied to a whole range of industrial and mechanical uses. They offer non-contact sensors which makes the mechanism more robust and resistant to natural wear and tear. There are different types of linear position sensors categorised according to several parameters such as measurement type, measurement range, intrinsic safety required, hazardous environment, and environmental sealing.

Measurement Type

The measurement type of the position sensor basically determines the kind of displacement it is intended for. For example, linear position sensors are meant to measure linear displacement or the movement of something to and fro. On the other hand, rotary sensors are designed to detect and measure movement around an axis.

Tilt sensors as the name suggests, are specifically used when the sensor will be applied to measure movement at an angle.

Measurement Range

Similar to the measurement type, positions sensors also differ depending on the range to which it will measure displacement. It can be in inches, degrees, or millimetres. Buyers should easily be able to determine the required measurement range for the sensor they need.

Intrinsic Safety Required


Buyers need to determine if intrinsic safety is required for the position sensor they are buying. This is important when the sensor is to be applied in hazardous conditions. Intrinsic safety can be approved by ATEX, IECEx, or CSA.

Hazardous Environment

Many position sensors today can be used in hazardous conditions. But the specification of a sensor also varies depending on the environment it will be subjected to. Mining, gas, vapour, and dust are some of the most common environment factors to consider when choosing a sensor.

Environmental Sealing

In conjunction with the other parameters, environmental sealing also determines how well a sensor performs in the type of environment it will be used in. Sealing protects the internal mechanism of a sensor and this is very important. For example, if the sensor will be submerged in water, the sensor should have environmental sealing that can withstand the pressure and depth.

With Positek’s online inventory, buyers can easily filter according to these parameters in order to narrow down your choices. If you are unsure of the specifications for the sensor you need, you can always call their support line for assistance. Similarly, Positek offers customisation if the specifications for the sensor you are looking for is not available in their current inventory.
