10Kg Load Cell Documentation
Overview
The 10Kg Load Cell is a transducer that converts weight or force into an electrical signal. It is commonly used in industrial, medical, and commercial applications for weighing and force measurement. This documentation provides a detailed explanation of the load cell's pins and their connections.
Pin Configuration
The 10Kg Load Cell has a total of 4 pins, labeled as E+, E-, S+, and S-. Each pin has a specific function, which is explained below:
Pinout Diagram
| Pin # | Pin Name | Function |
| --- | --- | --- |
| 1 | E+ | Excitation Positive |
| 2 | E- | Excitation Negative |
| 3 | S+ | Signal Positive |
| 4 | S- | Signal Negative |
Pin Description
1. E+ (Excitation Positive): This pin provides the positive voltage supply to the load cell's internal Wheatstone bridge circuit. Typically, a stable DC voltage source (e.g., 5V or 10V) is applied to this pin.
2. E- (Excitation Negative): This pin provides the negative voltage supply to the load cell's internal Wheatstone bridge circuit. This pin is connected to the negative terminal of the power supply, which is usually the ground or 0V reference.
3. S+ (Signal Positive): This pin outputs the amplified and conditioned weight or force signal from the load cell. The signal is typically an analog voltage signal that varies in proportion to the applied weight or force.
4. S- (Signal Negative): This pin is the reference point for the output signal and is usually connected to the ground or 0V reference.
Connection Structure
To use the 10Kg Load Cell, follow these connection steps:
Step 1: Power Connection
Connect the positive terminal of the power supply (e.g., 5V or 10V) to the E+ pin.
Connect the negative terminal of the power supply (e.g., GND or 0V) to the E- pin.
Step 2: Signal Connection
Connect the S+ pin to the input of an instrumentation amplifier or an analog-to-digital converter (ADC) for signal conditioning and processing.
Connect the S- pin to the ground or 0V reference point.
Important Notes
Ensure proper insulation and shielding of the load cell and connecting wires to minimize electromagnetic interference (EMI) and noise.
Use a stable and regulated power supply to minimize voltage fluctuations that may affect the load cell's accuracy.
Follow proper calibration and zeroing procedures for the load cell to ensure accurate weight or force measurements.
By following these connection guidelines and understanding the pin functions, you can successfully integrate the 10Kg Load Cell into your IoT project or application.
