HBM load cells are used to measure force, weight, and pressure with high accuracy and precision. They consist of a strain gauge that converts the mechanical deformation of an object into an electrical signal. To get the best performance from your HBM load cell, you need to wire it correctly. In this article, we will guide you through the steps of wiring an HBM load cell and explain the wiring diagram in detail.
What is an HBM Load Cell?
HBM load cells are transducers that measure force, weight, and pressure. They consist of a strain gauge that converts the mechanical deformation of an object into an electrical signal. HBM load cells are known for their high accuracy and precision, making them ideal for industrial applications such as automotive, aerospace, and manufacturing.
HBM load cells come in different types such as compression, tension, and bending. They can also come in different materials such as stainless steel, aluminum, and plastic. The type and material of the load cell you choose depend on your application requirements.
Wiring an HBM Load Cell
Wiring an HBM load cell is a simple process that requires a few components such as a load cell, an amplifier, and a power supply. The wiring diagram of an HBM load cell consists of four wires: excitation (+Vexc), ground (GND), signal (+Vs), and signal ground (SG).
The excitation voltage is the voltage supplied to the load cell to power it, and the signal voltage is the voltage produced by the load cell in response to the applied force. The amplifier then amplifies the signal voltage to a usable level.
Step-by-Step Guide to Wiring an HBM Load Cell
Here are the steps to wire an HBM load cell:
- Connect the excitation (+Vexc) wire of the load cell to the positive terminal of the power supply.
- Connect the ground (GND) wire of the load cell to the negative terminal of the power supply.
- Connect the signal (+Vs) wire of the load cell to the positive input of the amplifier.
- Connect the signal ground (SG) wire of the load cell to the negative input of the amplifier.
- Connect the output of the amplifier to your data acquisition system.
Once you have wired your load cell and amplifier, you can then calibrate the load cell to ensure accurate measurements. Calibration involves applying known weights to the load cell and adjusting the amplifier gain until the output is equal to the applied force.
