Rotary potentiometers, also known as rheostats, are electronic linear variable devices used to measure angular displacement, voltage, current, resistance, and several other types of electrical measurements in a variety of applications.

Introduction to PTV111-4425A-B105

The PTV111-4425A-B105 is an advanced rotary potentiometer developed by Techno-Tool Group, and it is particularly designed for detection of angular displacement in the range up to 3.5 degrees. It features an ergonomic design which fits perfectly into small spaces and offers a very short response time. With a wide power supply range (0-50mV to 0-300V), this unit is suitable for applications that require very precise angles, such as medical equipment, robotics, and automotive applications. The PTV111-4425A-B105 operates in a 110 kHz frequency range and can handle a maximum current of 0.2 amps, and a maximum voltage of 300V. The potentiometer is also enclosed in a flame retardant plastic housing, which is very durable and can survive temperatures up to 150C.

Working Principle

The PTV111-4425A-B105 uses a system of two resistive elements to measure the angular displacement of a shaft. The two resistive elements are connected in series, with a linear voltage divider going from the supply voltage to the output voltage. The voltage at the output is dependent on the rotation of the potentiometer\'s shaft. As the shaft is rotated, the relative resistances of the two resistive elements change, causing a change in the output voltage.

When the shaft is in its minimum angular position, the output voltage is zero. As the shaft is rotated, the output voltage increases linearly with the angle of rotation. When the shaft is rotated all the way to its maximum position, the output voltage reaches its maximum value. The PTV111-4425A-B105 has a resolution of 0.17 degrees, which is very accurate.

Applications

The PTV111-4425A-B105 can be used in a variety of applications, including medical equipment, robotics, automotive, and industrial applications. The small size and low power consumption make it ideal for medical applications such as electrocardiograms (ECG) and other medical imaging systems. The high accuracy and the wide range of input and output signals make it suitable for use in robotics, where accuracy is paramount. Similarly, it can be used in automotive applications where a precise angle measurement is required. Finally, the PTV111-4425A-B105 can also be used in industrial applications such as fluid level or pressure measurement.
