YZC-131 3kg Aluminum Load Cell Sensor with 18cm Wires

The YZC-131 is designed for cantilever (bending beam) mounting. Securely fix one end using the provided mounting hole, leaving the other end free to deflect under load. Ensure the force is applied perpendicular to the labeled direction on the cell body. Avoid applying direct pressure to the central white plastic cover area to prevent damage to the internal strain gauges.

You need a precision instrumentation amplifier or a dedicated load cell amplifier module like the HX711. Connect the load cell's four wires (typically red, black, white, green) to the corresponding inputs on the HX711. Then, connect the HX711's DATA and CLK pins to digital I/O pins on your Arduino. The HX711 library handles the 24-bit ADC conversion and provides a calibrated weight reading.

A 1.0 mV/V output means that for every 1 Volt of excitation voltage applied to the load cell's input terminals, the full-scale output signal will be 1.0 millivolts. The recommended excitation voltage is 5 to 10V DC. Applying 5V will give you a maximum output of 5mV at full load (3kg), while 10V will give 10mV, improving the signal-to-noise ratio.

Yes, the YZC-131 can measure both compression and tension, as it is a bidirectional load cell. The output voltage polarity will change depending on the direction of force. A positive voltage change typically indicates a compressive force (pushing down on the free end), while a negative change indicates a tensile force (pulling up on the free end).

IP65 means the load cell is dust-tight (6) and protected against low-pressure water jets from any direction (5). This makes it suitable for use in environments where it may be exposed to dust, occasional splashing, or wash-downs, such as in food processing areas, workshops, or outdoor applications, provided the operating temperature range of -21°C to 40°C is respected.
