Position Sensors

How does this sensor work?

The position sensor is also called an integrated circuit, which measures the movement and position of an object. These measures or patterns are converted into analogue and digital signals output. Position sensor is crucial to take information to\from a fixed part and output the outcome. Many sensors exist in the industry for different purposes. A famous position sensor is a Linear Variable Differential Transformer (LVDT).

What things or movements this sensor measuring

Position sensor measuring patterns in a range of various methods; such methods are as follows:

• Rotation of rotary objects
• Measuring object by angle
• Measuring object precision and accuracy
• Distant object measurement

Linear position sensor

The linear position sensor accurately measures the object's position and measures the linear posture of the object. Linearity is crucial for technical or engineering applications—it measures the position of an object linearly.

Rotary Position Sensor

As the name suggests, this sensor measures the object angle wise to represent the angular position of an object. 

Resistive position sensor

This resistive position sensor is resistant to measuring the position. This sensor can be used in various applications; a few of them are as follows:

• Intelligent machines or robotic
• Smart home appliances
• Gaming lighting
• Television and computer 
• Automation and control system
• Coordinate measurement 
• Industrial motion control

Uses of Position Sensor

A position sensor is an intelligent device that measures object patterns or movement. It transforms the patterns and movement into output signals. The most used and common types of position sensor are inductive, capacitive, and LVITs. Each of them comes up with different embedded technologies. Engineers or technicians can choose the right style for their application based on definite properties and features. The critical point here is to select the correct sensor for a specific application. Once the suitable sensor is installed, it will accurately carry out all the tasks.

Types of different sensors

Position sensor comes with varying compatibility and potential capabilities. The most used standard type is a rotary encoder, whose shape is the same as a potentiometer. It transforms the angular position of a rotating object into an analogue or digital output signal. These sensors are a cost-effective, simple and easy installation option for any industry. These sensors are very useful in the industry today. A rotary encoder is available worldwide, affordable and installation is very simple. It helps measure the position of a rotating object without the cost of its physical connection.

Another type of sensor is called, Inductive position sensor that measures the distance between a magnetic object and a wire loop. This sensor is typically used to measure the distance between the coil and the magnetic object. As a result, Inductive sensor require a current to measure the inductance of an object and can be installed anywhere in the environment.
