Ultrasonic linear position sensors rely on radar to perform their job efficiently. They fix ultrasound waves reflected from the object. The time delay between the sending and receiving of ultrasonic pulses can measure the distance to an object with an accuracy reaching up to several tenths of a millimeter.
 
A position sensor is a device designed to determine the linear or angular mechanical displacement of certain objects. These devices have a huge number of practical applications in various fields, so there are many classes of position sensors, which vary according to the principle of action, accuracy, cost and other parameters. It should immediately be noted that all position sensors can be divided into two main categories – linear position sensors and angular position sensors (encoders). As part of this review we will focus on linear position sensors.
 
According to the principle of the work, linear position sensors can be:
 
• Capacitive
• Optical
• Inductive
• Ultrasound
• Potentiometric
• Magnetostrictive
 
There are many variations ...
... of linear position sensors based on various optical effects. Perhaps the most popular model is the optical configuration. A position sensor is a range finder, which determines the distance to the object of interest, fixing the radiation scattered by the surface of the object and determining the angle of reflection, which makes it possible to determine the distance to the object. An important advantage of the majority of optical sensors is the ability to perform non-contact measurements; in addition such sensors are usually pretty accurate and perform at a very high level.
 
Another popular type of linear position sensors is ultrasonic. Ultrasonic linear position sensors work on the sole principle of radar. Time delay between the sending and receiving of ultrasonic pulses can measure the distance to an object with an accuracy reaching up to several tenths of a millimeter. Ultrasonic and Optical linear position sensors to date are probably the most versatile and technologically advanced non-contact measurement tools available.
 
Spheres are the places and conditions where all types of linear position sensors can be used. The variety of spheres where they can be used today is really impressive and important for a number of different industries. The sensors can be used in underwater equipment for safety and performance monitoring. They can be used in unmanned drones, planes, etc. to predict tsunami and earthquakes. They are often used to detect movement and protect your house or office from robberies. They can even be used in something fun such as bowling for scoring systems.
 
When choosing a linear position sensor, you need to check between different models for the one that suits your individual requirements. Go to professionals who will help you to choose the correct linear position sensor model, which will meet your needs and goals. Ask them to help you choose the most reliable type of linear position sensor.
 
A wide range of linear position sensors are available, offering diverse stroke length measurements. Varied technologies including potentiometric, inductive, eddy current and Hall effect are used for manufacturing the sensors with mountings that give the user several flexible installation options. A hi-tech linear position sensor is designed to eliminate wire, and cut assembly costs. These sensors have proven to be useful for a multitude of applications in different industries. They have relatively non-critical alignment requirements, are easy to install and come in compact sizes.
