Phaeton CZL-635NB 3KG Aluminum Load Cell Sensor

The CZL-635NB load cell is designed for standard excitation voltages of 5V DC or 10V DC. The output signal is ratiometric, meaning the measured millivolt output is directly proportional to the applied excitation voltage. Using a stable, low-noise voltage source is critical for achieving accurate weight measurements.

Connect the load cell's four wires: Red to Excitation+, Green to Excitation-, Black to Signal+, and White to Signal-. You will need a precision instrumentation amplifier or a dedicated load cell amplifier module (e.g., HX711) to boost the small mV signal and convert it to a digital format. The HX711 communicates via a simple serial interface (DATA and SCK pins) with an Arduino or other microcontroller.

The 2-3 kg specification indicates the sensor's optimal operating range. The 3 kg value is the rated capacity or full-scale load. Applying loads up to 3 kg ensures specified accuracy and linearity. Exceeding this capacity may cause permanent damage or calibration shift. For best performance, select a load cell with a capacity slightly above your maximum expected load.

Yes, multiple load cells can be combined in a parallel configuration (e.g., for a platform scale). They should be connected to a summing junction box that averages their outputs before sending the combined signal to a single amplifier. All cells must be identical models, mounted identically, and properly calibrated together to ensure accurate total weight measurement.
