4. Functionality
The MDR4607 functions as a resistance-to-voltage converter. It measures the resistance of a connected sensor or circuit element and translates that resistance value into a proportional analog voltage output. The conversion is linear across the specified range (0 Ω – 100 kΩ), with the output varying between –5 V and +5 V.
Operating Principle:
1. The module applies a stable excitation current or voltage to the resistive element under test.
2. It measures the resulting voltage drop or current flow, calculates the corresponding resistance, and converts it into a proportional voltage signal.
3. The output voltage is scaled such that 0 Ω corresponds to –5 V and 100 kΩ corresponds to +5 V (or vice versa, depending on configuration).
Use Cases and Applications:
- Industrial Process Monitoring: Measuring resistive sensors such as thermistors, potentiometers, or strain gauges.
