- The resulting voltage drop or current flow is measured internally and converted into a proportional voltage signal.
- The output is scaled linearly, such that 0 Ω corresponds to −5 V, 10 kΩ corresponds to +5 V (or vice versa, depending on configuration).
- The low-frequency response (DC – 4 Hz) ensures accurate tracking of slow or static resistance changes, making it ideal for sensors such as thermistors, potentiometers, strain gauges (in resistive mode), or other resistive transducers.
Use Cases and Applications:
- Industrial Process Monitoring: Measuring resistive sensors in temperature, pressure, or displacement monitoring systems.
