The **TCS-80-R/CE** is a high-precision electronic counting scale, typically used in industrial and commercial environments for inventory management and parts counting. Below is a breakdown of its primary electronic components and technical specifications. --- ### 1. Core Electronic Components The functionality of the TCS-80-R/CE relies on several key electronic assemblies: | Component | Description | Function | | :--- | :--- | :--- | | **Load Cell** | High-precision strain gauge sensor | Converts physical weight into a measurable electrical signal. | | **A/D Converter** | Analog-to-Digital Integrated Circuit | Converts the low-voltage analog signal from the load cell into digital data for the CPU. | | **Microcontroller (MCU)** | Central Processing Unit | Processes weight data, handles unit conversions (kg/lb), and manages the counting logic. | | **Display Panel** | Triple Window LCD/LED | Simultaneously displays Weight, Unit Weight, and Total Quantity. | | **Keypad** | Membrane or Mechanical switch matrix | Allows for Tare, Zero, Sample size entry, and alarm limit settings. | | **Power Supply** | AC Transformer & DC Battery Circuit | Manages 220V/110V input and regulates charging for the internal lead-acid battery. | --- ### 2. Technical Specifications The electronic logic of the device is calibrated to provide high-resolution results. - **Maximum Capacity:** 80 kg (Standard for the 80-R series). - **Readability/Division:** Usually 2g or 5g depending on specific calibration. - **Internal Resolution:** Often 1/30,000 or higher for accurate piece counting. - **Interface:** RS-232 Port (Optional/Standard on CE models) for connecting to thermal printers or PCs. --- ### 3. Key Electronic Features 1. **Automatic Piece Weight Update:** The internal software automatically refines the average piece weight as more items are added to the scale, reducing margin of error. 2. **Accumulation Function:** The electronic memory allows for the accumulation of multiple weighings to provide a grand total quantity. 3. **Alarm/Check-Weighing:** Electronic buzzers can be programmed to sound when a specific quantity or weight limit is reached (Hi/Lo/Ok). 4. **Battery Management:** Includes a low-battery indicator and an automatic "power-save" mode to extend the life of the internal rechargeable battery. --- ### 4. Communication Protocol (Example) If the scale is equipped with an RS-232 interface, the data output typically follows a standard serial format: ```text Baud Rate: 9600 Data Bits: 8 Stop Bits: 1 Parity: None Example String: ST,GS,+ 1.500kg (Status, Type, Weight) ```
