Analog Loadcell:

An analog load cell is a weight-sensing device that converts mechanical force (like weight or load) into a proportional analog electrical signal, typically in millivolts per volt (mV/V). This signal is generated by strain gauges inside the load cell, which change resistance when the load is applied. The analog signal is then sent to an external indicator or amplifier for processing and display.

• Output Signal: Low voltage analog signal(mV).
• Signal Type: Continuous, susceptible to electrical noise.
• Requires: External amplifier or analog-to-digital converter (ADC).
• Common Use: Traditional weighbridges, tank scales, platform scales, industrial weighing.

Digital Loadcell:

A digital load cell is a type of weight sensor that converts mechanical force into a digital signal directly within the load cell. It combines a traditional strain gauge sensor with built-in electronics that amplify, filter, and digitize the signal before outputting it via a digital communication protocol (e.g., RS-485, CAN, MODBUS).

• Output Signal: Digital (e.g., RS-485, MODBUS, CAN).
• Built-in Electronics: Includes amplifier, analog-to-digital converter (ADC), and microcontroller.
• High Accuracy: Reduced signal noise and better resolution.
• Plug & Play: Factory calibrated; easy to integrate with digital systems.
• Self-Diagnostics: Can detect errors, overloads, and temperature issues.
• Common Use: Automated weighbridges, batching systems, smart weighing setups.
