Digital Signal Content

What Are Digital Load Cells? Digital load cells (DLFC) work in a very similar way to other RFID readers. They have a set range of operation frequencies that can be manipulated by the transmitter to obtain a specified signal strength. The basic difference lies in the fact that digital signals are processed much faster than analog ones, making digital load cell usage very effective when it comes to storing and monitoring information for a short period of time.

What Are Digital Load Cells?

DLFCs consist of two independent circuits, one for the electrical output signal and one for the detection of a change in the electrical input signal. Modern digital load cells are manufactured on flexible PCB (printed circuit board) and contain the necessary components such as capacitors, resistors and Alps switches. When the electric current passes through the foil strain gauge, an optical output performs the required reading. When the electrical output signal changes, the mechanical analog switch is forced to move, causing the change in the electrical input signal.

Digital load cells have the advantage that they are capable of detecting either a change in the electrical output signal, or an increase in the mechanical analog switch force. Although this technology offers great flexibility, modern DLFC devices are also able to store high-volume data. This is done by the addition of a random access memory (RAM) to the device, which operates on digital signal content.

Digital Load Cell Basics

Digital load cells are used to supply alternating current power to electronic equipment such as motors, lights and fans. Although digital load cells have become a common replacement for lead acid flooded batteries, they have also become a popular alternative for many consumers who prefer to run their appliances on batteries. There are three major differences between these types of load cells: the signal processing unit, the data processing unit and the battery itself. Understanding these differences will help you decide which type is right for your needs.

Maximum Efficiency

All load cells are made up of a series of positive and negative terminals that receive an electric signal that is applied across the terminals. Because analog signals are passed through resistive or non-resistance parts, the behavior of the signal can be highly predictable. Modern digital load cells use microprocessor chips that perform the circuitry within the cell and alter the signal depending upon the condition of the device connected to the circuit. Digital signal processing in digital load cells is accomplished by adjusting the threshold voltage signal levels and application requirements to achieve the most accurate results.

Digital signal processing in digital load cell applications is achieved by adjusting the gain, threshold, pulse width, and duty cycle of the digital signal so that the desired circuit operation is obtained. This allows the circuit to run at its maximum efficiency even if all other components are operating at high speeds. Some digital signal processing functions include amplitude modulation (AM), tone control, bit reversal, and linear output control. The signal content of analog systems is always constant, whereas digital systems can vary from one cycle to another (or even from one microamp to another) due to signal saturation or noise.
