Guide to Positek’s Range of Position Sensors


Displacement measurement is an essential part of mechanical processes. Many industries today rely on position sensors for quality control and as a safety feature of many machines. Position sensor technology had come a long way since its earliest inception before the Second World War began. Today, sensors are present in almost industry imaginable, from research, industrial, telecommunications, transportation, and agriculture. Whether the application is on air, underwater, underground, or above-ground, there is a position sensor fit for whatever the job requires.

What are the advantages of non-contact sensor technology?

A linear position sensor either uses a contacting or non-contacting method of measurement. One example of a contacting sensor is a potentiometer. A potentiometer has a resistive track connected to the target object where the resistance measured equates to the displacement. Potentiometers are relatively economical and readily available. These are also simple to use. However, because the sensor comes in contact with the target object, wear and tear eventually affect the sensor’s performance. As such, potentiometers are not suitable for high-friction and high-vibration applications.

In contrast, a non-contacting Linear transducer or LVDT consists of coils inside a hollow tube. The mechanism does not come in contact with the target object; thus eliminating the effect of friction. Positek manufactures a Linear position sensor using a patented inductive non-contact technology which makes them suitable for applications exposed to extreme conditions.

The future of position sensors

Position sensor technology continues to evolve as manufacturers and engineer find new and innovative techniques and experimenting with materials that further improve on the robustness of these devices. For example, there are LVDT’s that produce digital output compatible with computer systems. Linear sensors are also more affordable, yet perform better than before.

New materials introduced in producing sensors opened the possibility of application to extremely hostile environments. Exotic alloys used in sensor construction such as cobalt and nickel allow for sensor application in extreme temperature conditions and the presence of acid compounds. Hermetic sealing also enables specific sensors perform well in high-pressure environments such as underwater.

Are Positek’s sensors reliable?

Positek manufactures position sensors from high-quality materials using advanced engineering methods. With their patented non-contact technology, each position sensor is guaranteed to have extensive, reliable readings even when subjected to extreme working environments. Positek received awards and certifications for their outstanding work in position sensor manufacturing.

How many varieties of sensors does Positek produce?

Positek has a wide array of off-the-shelf sensors ready for installation. You can choose a sensor according to movement type, measurement type, the range of measurement, intrinsic safety required, and hazardous environment sealing. You can select from an extensive array of linear position sensors, rotary sensors, submersible sensors, and cylinder position sensors. Positek also custom builds sensor’s if you can’t find a sensor with the exact specifications you need.
