Voltage Transducer

A voltage transducer measures AC or DC voltage and converts the measured voltage into a proportional analog output signal. Measuring voltage is crucial in ensuring accuracy and safety in critical applications. Transducers are also used in manufacturing and industrial applications to monitor and control both processes and equipment.

A voltage transducer is a device that measures AC or DC voltage and converts the measured voltage into a proportional analog output signal used for monitoring and controlling electrical systems.

Yes, a voltage transducer is sometimes called a voltage sensor and less frequently a voltage transmitter.

A voltage transducer measures the voltage between two line inputs and provides an output signal that is proportional to the measured input voltage. The analog output is then fed to an analog input card of a process control device such as a Programmable Logic Controller (PLC), Distributed Control System (DCS) or a digital display, capable of accepting an analog input.

Yes, all voltage transducers from NK Technologies are UL/cUL listed and CE certified.

Like voltage transducers, current transducers (also called current sensors) are used in manufacturing and industrial applications to monitor processes and control equipment. Current transducers can provide similar benefits as voltage transducers but measure electrical current instead of voltage. They measure an input current and provide a proportional analog output signal.

NK Technologies offers a variety of voltage transducers to fit your needs including AC only, DC only, either AC or DC and finally, bidirectional DC.  All models are offered across multiple voltage ranges.

Voltage Transducers are widely used in industrial control systems, power supply monitoring, battery management systems, high-speed rail systems, and renewable energy systems. Any place that needs accurate voltage monitoring.

Each application will have unique requirements. To choose the right voltage transducer, gather the following key criteria:

  • What input range is being measured?
    • Is the voltage AC or DC? If DC voltage, is it bidirectional DC voltage?
  • What is your output signal?
    • How will data be collected?
    • Voltage Signal {0-5 VDC, 0-10 VDC} or Current Signal {4-20 mA}
  • Will your installation be loop powered or require an external power supply (24 VAC/VDC or 120 VAC)?
  • Do you require a DIN Rail Mount or a Panel Mount?
  • Does your application require a UL/cUL or CE certified product?

NK Technologies makes a complete line of Voltage Transducers that measure a variety of AC and DC Voltage Ranges and have the following features:

  • “True RMS” for more accurate measurement results compared to “Averaging” transducers.
  • DIN Rail or Panel Mount options
  • UL/cUL and CE certified

All models of NK Technologies voltage transducer cases support both DIN rail and panel mount installation.

Voltage transducers improve safety by monitoring voltage levels and can activate alarms or shut down systems if irregularities are detected.

Yes, there are voltage transducers designed for AC, DC, or both types of voltage measurements and can even be bidirectional.

Installation involves connecting the transducer input to the voltage source and the output to the monitoring or control system. Follow all manufacturer's guidelines and safety standards.

Connect the input voltage that you’d like to measure, the output signal, and a power supply depending on your needs.
