In various electrical systems and applications, accurately measuring and monitoring voltage is essential for maintaining optimal performance and safety. Voltage transducers, also known as voltage sensors or voltage transmitters, are devices that facilitate the measurement and conversion of electrical voltage into a form that can be easily utilized for monitoring and control purposes. These transducers play a crucial role in numerous industries, including power distribution, renewable energy, industrial automation, and more.
Voltage or AC transducers come in two different formats:
Absolute average measuring: These devices are calibrated using RMS and they are considered to be one of the most inexpensive transducers. These devices convert AC input to DC and they are calibrated based on the root mean square for their sine wave input. This type of voltage transducer works in an adequate measure for a number of situations in which the wave shape does not produce any type of distortion. Utilizing the other type of voltage transducer is a good idea if there is distortion in the wave.

True RMS: A True RMS transducer is responsible for calculating RMS value from voltage input and then providing proper output. The DC output is delivered on an effective value based on the input voltage. This type of transducer comes with an advantage when the voltage is regularly distorted. These models are available with set input voltages including 480 V, 240 V, 120 V and 69 V. The measuring range on true RMS goes from zero up to 125%. 120 V models typically range between zero and 250 V. If you are planning on dealing with an input that is higher than 600 V it could be wise to consider using a full transformer over a voltage transducer.
How Does a Transducer Work?
A transducer is a device that converts energy from one form to another. Usually, a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction.
The working principle of a transducer is based on the interaction between two or more physical quantities. For example, a temperature transducer may use a bimetallic strip to convert temperature into an electrical signal. The bimetallic strip is made of two different metals that have different coefficients of thermal expansion. When the temperature changes, the bimetallic strip bends, which changes the resistance of the strip. This change in resistance is then converted into an electrical signal.
The output signal from a transducer is typically an electrical signal. This signal can then be amplified, filtered, and processed by other devices. The processed signal can then be used to measure the physical quantity that the transducer is converting.
Types of Voltage Transducers
A voltage transducer plays a crucial role in converting electrical voltage into an equivalent electrical signal that can be utilized in various applications. Voltage transducers play a crucial role in modern measurement and control systems by converting various physical quantities into proportional electrical signals. These transducers enable the measurement of quantities such as pressure, level, temperature, displacement, and more, transforming them into usable electrical outputs in the form of voltage or electric current.
Resistive Voltage Transducers
Resistive voltage transducers employ a resistor to convert the input voltage into a proportional current. This current is subsequently amplified and transformed into a voltage signal, allowing for precise measurements and control.
Inductive Voltage Transducers
Inductive voltage transducers utilize a coil to convert the input voltage into a proportional magnetic field. This magnetic field is then sensed and translated into a voltage signal, providing accurate readings and enabling effective control.

Classification and Features
Voltage transducers can be classified based on their input voltage range, output signal type, and accuracy. The following key characteristics influence their performance and application suitability:
Input Voltage Range
Voltage transducers cater to a wide range of input voltage requirements, spanning from a few volts to several kilovolts. This versatility ensures compatibility with various electrical systems and voltage levels.
Output Signal Type
Voltage transducers offer flexibility in terms of output signal types, which can include current, voltage, or frequency. This adaptability allows seamless integration with diverse instrumentation and control setups.
Accuracy
The accuracy of a voltage transducer is typically expressed as a percentage of its full-scale measurement capability. Precise and reliable measurements are vital for maintaining system integrity and ensuring optimal performance.
The Best Features to Look For
The best features include an industry-standard output for existing controllers with data loggers. Some form of reliability with equipment and an ongoing log can make sure that any causes for concern can be regularly monitored.

Input and Output Isolation
Input and output isolation can also ensure improved safety with a voltage transducer. Having circuitry that is properly isolated ensures that there is less of a chance for accidents that could occur and that the device can see safer operation over time.
Compact Construction
The latest voltage transducers come with space-saving designs and this can ensure that the mounts can be installed in smaller enclosures while taking up less space throughout the electrical grid by using these smaller and space-saving designs, it’s possible to include more of these devices throughout commercial grids and in industrial settings.
