Custom-designed Position Sensors from Positek

Positek customises position sensors to cater to unique specifications for a variety of industrial applications. Custom sensors produce precise measurements and eliminate the need for calibration and adjustments.

Sophisticated process controls in various industries use position sensors to detect object displacement. Aside from measuring movement, sensors also help with specific functions in automation. Without these compact devices, many industries would not have advanced in the manner we know today.

The earliest known application of position sensors was in laboratories before World War II. Back then, the potential of position sensors in versatile applications has yet to be discovered. During that time, it was impractical to mass-produce sensors because of the cost. Fast forward to decades later, a Position sensor is about as commonplace as any mechanical device.

Different types of position sensors


Position sensors fall under different categories. In terms of specifications alone, you can distinguish a linear position sensor according to measurement range and measurement and output type. A broader category used in selecting a
Linear position sensor which suits a particular application is according to the working principle.

Photoelectric sensor. A linear transducer using a photoelectric working principle uses light detection and projection to produce an output. Fibre optic sensors and sensors measuring optical triangulation and time of flight fall under this category.

Eddy-current sensors. An eddy-current sensor is also known as a proximity sensor. Although this type of sensor is not strictly used to measure position, it is used to detect the proximity of an object within or in front of the sensor. It uses a magnetic field for detection. An eddy-current sensor is another prime example of a non-contact or inductive sensor.

Capacitance sensor. A capacitance Linear transducer uses non-contact technology which measures the voltage difference applied on the sensor and the target object. Although capacitance sensors are suitable for conductive and non-conductive materials, they are sensitive to environmental interference such as wind.

Linear potentiometers. Potentiometers use a resistive track and a wiper to measure the displacement of an object. This type of linear position sensor is the simplest type of sensor and is also economical to use. Potentiometers are easy to install and troubleshoot which makes them a suitable option for industrial applications. Since potentiometers use contacting technology, they don't fare well in extreme working conditions. Nevertheless, for lighter applications, potentiometers often prove to be the best choice.

Ultrasonic sensor. In contrast to a photoelectric sensor, an ultrasonic
linear transducer makes use of sound projection and detection to detect object displacement.

Sensor output types include analog, time-based digital, and serial-digital. Positek has a vast inventory of off-the-shelf sensors fitting a range of industrial applications whether above-ground, submerged underwater, and even on air.

Positek's custom designed position sensors

Although Positek ensures that their inventory always includes a wide variety of sensors to cater to every buyer's needs, there are certain situations when unique specifications not found in off-the-shelf products require customisation.

Each
custom position sensor by Positek is one-of-a-kind and are produced using the same patented non-contact technology used in all their sensors. If you are looking for a Cylinder Position Sensor with a measurement range or in a size not found in our inventory, you can contact one of our product engineers for consultation.

Our engineers will collaborate on the design and manufacture the custom position sensor in an onsite facility to guarantee quality. Within a few working days, you will have your custom sensor delivered, ready for installation.

What sets Positek's custom-designed sensors apart from other manufacturers is that we don't charge for the design consultation. There are no restrictions on the size of the sensor you want to be produced which means that you have more flexibility in having a precise sensor built for them as the application requires.

Why trust Positek's position sensors?

Positek understands that position sensors need to be reliable and robust. Positek also caters to many clients that use sensors for applications in extreme conditions. As such, you can rely on Positek to produce sensors meeting the highest standards of quality.

Positek has been in business for over 25 years and continues to build and innovate on the technology used to manufacture sensors for modern day applications.

Positek also ensures compliance with industry regulations so that each product meets quality standards set by various regulators. Positek also received certifications and awards to vouch for their exceptional history in manufacturing position sensors used in multiple fields of application.
