What are Position Sensors

Position sensors are basically sensors for measuring the distance travelled by the body starting from its reference position. How far the body has moved from its reference or initial position is sensed by the position sensor potentiometer and often the output is given as a fed back to the control system which takes the appropriate action. Motion of the body can be rectilinear or curvilinear; accordingly, position sensors are called linear position sensors or angular position sensors.

The classification of Sensor

Most common way of classifying the wide spectrum of sensors is based on the specific application of the digital sensor. Sensor used for measuring humidity is termed as humidity sensor, the one used for measurement of pressure is called pressure sensor, sensor used for measurement of liquid level is called level sensor and so on though all of them may be using the same sensing principle. In a similar fashion, the sensor used for measurement of position is called a sensor position.

Types of Position Sensor

Linear position sensors are very important organs of any measurement system. They collect data from the surroundings/ physical parameter and provide electrical signal as the input to the systems. Amongst wide variety of sensors operating on different sensing principles and used in different applications, position sensors play an important role in different systems. Whether it is fly-by-wire aircraft systems, drive-by-wire cars, bullet trains taking round curves, injection molding machines, packaging machines, medical equipments, and so on, industrial position sensors finds their applications, of course in different ways.

Potentiometric linear transducer

For linear position sensing detections and length measurements, Huiren Electronics linear sensors are available in different forms with four different measuring principles. A broad range of applications with measuring strokes from 2mm to 4000mm, can be implemented. Which measuring principle is best suited for the respective measuring task depends on the ambient conditions, the dynamics, the specified precision and, of course, the distance to be measured. Economic factors also play a role in choosing the right sensor type in order to achieve the best possible cost-effectiveness ratio.

The spring return version of the potentiometer

The push rod can be equipped with an inside spring return to center potentiometer device. The spring return version of the potentiometer makes the sensor space saving and robust, because of the front guided construction and 6mm diameter in the push rod. For mount potentiometer has four fixing clamps which are included in the scope of supply. To ensure high accuracy and long lifetime for a good price performance ratio the potentiometric measuring principle is realized with a high-resolution conductive plastic resistance element. Since the potentiometric measuring principle delivers absolute values and requires no electronic conversion, the position feedback signal is true power on without delay, temperature stable.

The mechanical detection of linear displacement sensor

In the Miniature linear displacement sensor the mechanical detection of linear movement is done by a slider cursor. The cursor construction of the sensor provides space saving integration up to 2000mm measurement stroke. To avoid vertical or angular misalignment a link ball is integrated in the cursor sled. For rough environmental conditions we recommend mounting the sensor in overhead position. A drip edge and a special cover under the sled prevent ingress of dust into the sensor. To ensure high accuracy and long lifetime for a good price performance ratio the position sensor potentiometer measuring principle is realized with a high-resolution conductive plastic resistance element. Since the potentiometric measuring principle delivers absolute values and requires no electronic conversion, the position feedback signal is true power on without delay, temperature stable and robust against EMC influences.

Huiren Electronics hall effect potentiometer for applications

For applications in constantly vibrating environments, Huiren Electronics offers special potentiometers with the latest sensor equipment based on the hall effect potentiometer joystick technology. These sensors function 100% Contactless potentiometer and wear-free. The product group of cement coated wirewound resistors (potentiometers) comprises the single elements and the potentiometer units composed of the single elements. The units are available in different degrees of protection and mounting methods. Upon request these resistors are also manufactured with motor drive for AC and DC voltage.
