Data Acquisition - Digital Potentiometers

Digital potentiometers are electronic devices or integrated circuits that offer manageable resistance, precisely like a machine like a rheostat or a Potentiometer. However, they are managed by microelectronic signals instead of any mechanical response. 

The amount of electrical power degenerated in the resistance is relatively less, in the capability to be electronically managed enables self-propelledness, distant controlling the level of the waveform analog routes and shrinking wherever automatic Potentiometer may then be used.

What is a Potentiometer Made of?

We now understand the fundamentals of resistors and how they operate. A potentiometer is a variable resistor that changes resistance, current, and voltage via a circuit to get a specific output. You may have all seen a potentiometer in your physics lab. A potentiometer is just a variable resistor, also known as a rheostat. It is made up of a metal coil wound on a cylindrical platform with a sliding contact that is used to regulate the resistance of a circuit.

Advantages of Potentiometer:

• A potentiometer is easily functionalized. It is simple to use.
• It has a variety of conflict standards.
• It is as simply structured as possible, a three-routed component with a sliding that generates a manageable voltage distributor.
• It functions as a resistor variable or rheostat when only the two terminals are used.
• They are available at a meagre price at Enrgtech; you can buy hundreds of potentiometers according to their functionality and requirement.
• Produces high performance and low noise.
• Low power consumption.
• The protection degree is very high, no less than IP69(k).
• Highly efficient enables quantifying the variation in potential among two points.
• It is reliable because of its accuracy.
• Error encounters are significantly less.
• Highly proven technology. It has been used in engineering for more than a hundred years.
• Compared to analog potentiometers, digital potentiometers are more accurate.
• Potentiometers can also be used in volume-managing devices, transducers, televisions, alarm systems, dimers, relays, and healthcare machines.
• Has a long life expectancy. It can be used for many years flawlessly.

Types of Potentiometer:

The major two types of potentiometers are discussed below in detail:

Linear Potentiometer - One kind of position sensor is a linear potentiometer. They are employed to gauge movement along a single axis, either left and right or up and down. Rod actuation and connection to an internal slider or wiper carrier are common features of linear potentiometers. There are various application that are operated by Linear Potentiometer, that include:

• Agricultural Equipment
• Laboratory/Testing application
• Automobiles
• Healthcare
• Artificial intelligence
• Industrial devices
• Sport cars    

Rotary Potentiometer - A three-terminal device called a rotary potentiometer (Pot) uses a resistive element and a rotating contact to provide a variable voltage divider. It functions as a variable resistor or rheostat if only the adjustable contact and one end of the element are utilised as terminals.

Application Areas of Potentiometer:

Major application areas of the Potentiometer are given below:

• The Potentiometer is used in the injector of shape-forming machines.
• Healthcare devices
• Wood managing machines
• Used in a wide range of controlling various equipment tasks and as a user-managing device.
• It distributes electric current in an electronic circuit.
