Phaeton CZL-611E Load Cell Sensor 200KG Downforce - Screw-Fastened

The CZL-611E is designed for use with a typical DC excitation voltage between 5V and 12V. Applying voltage within this range ensures the sensor outputs its specified 1.2mV/V sensitivity correctly. Exceeding the maximum recommended voltage can cause overheating and damage the internal strain gauges.

Connect the red wire to the positive excitation input (+Exc), the green wire to the negative excitation input (-Exc). The black wire is the positive signal output (+Sig) and the white wire is the negative signal output (-Sig). This 4-wire configuration helps compensate for lead wire resistance, providing a more stable and accurate measurement signal to your instrumentation amplifier or data acquisition module.

The CZL-611E is primarily designed as a downforce (compression) load cell. Its mechanical structure is optimized for forces applied in one direction. Using it for tension (pulling) forces is not recommended unless explicitly stated by the manufacturer, as it may affect calibration, accuracy, and potentially damage the sensor.

You will need a precision instrumentation amplifier or a dedicated load cell amplifier module (HX711 is a common IC). These devices amplify the small millivolt-level differential signal from the load cell's Wheatstone bridge, filter noise, and provide a stable, higher-level voltage (e.g., 0-5V) or digital output readable by microcontrollers like Arduino, PLCs, or data loggers.
