Resistance and Potentiometers

The Signal converters for resistors and potentiometers are electronic devices designed to transform resistance signals, such as those generated by potentiometers, linear transducers, positioners with resistive output, into standard analog signals. This conversion allows resistance variations to be translated into voltage or current signals that can be easily processed by control and monitoring systems.

Main functions:

  • Signal conversion: They transform resistance signals into standard analog signals, facilitating the integration of potentiometers into control systems.
  • Galvanic isolation: They provide isolation between the input and output signals, protecting the equipment from possible interference or potential differences.
  • Amplification and linearization: They adjust and amplify the signal to ensure a precise and linear output, improving the accuracy of the measurements.

Common applications:

  • Industrial automation: Integration of potentiometers in control systems to measure variables such as position, speed or pressure.
  • Laboratory instrumentation: Conversion of resistance signals for analysis and monitoring in research environments.
  • Weighing systems: Interface between load cells and data acquisition systems, facilitating the measurement of weight and force.

When selecting a signal converter for resistors and potentiometers, it is essential to consider factors such as input range, accuracy, compatibility with the control system, and environmental operating conditions. These devices ensure effective communication between resistance sensors and monitoring or control systems, ensuring accurate and reliable measurements.
