The **FRTS-AA-R** is a high-precision digital force gauge and texture analyzer sensor, typically manufactured by **Imada**. It is part of the FRTS series, which is specifically designed for food texture analysis (e.g., measuring hardness, stickiness, or elasticity). Below is the technical breakdown of its electronic components and specifications. --- ### 1. Core Electronic Components | Component | Function | | :--- | :--- | | **Load Cell** | The primary transducer that converts mechanical force into a low-voltage analog signal. | | **A/D Converter** | High-speed Analog-to-Digital converter that processes data at high sampling rates (typically 2000Hz). | | **Microprocessor** | Manages data calculation, unit conversion (N, kgf, lbf), and system logic. | | **OLED/LCD Interface** | Provides visual output for force curves and peak values. | | **USB/RS232 Port** | Electronic interface for data transmission to a PC or PLC. | --- ### 2. Technical Specifications The "AA-R" designation usually refers to a specific capacity and sensitivity range within the FRTS series. | Feature | Specification (Typical) | | :--- | :--- | | **Max Capacity** | Usually 5N, 50N, or 100N (Model dependent) | | **Sampling Rate** | 2000 data points per second (Max) | | **Output Signal** | USB (for PC), RS232C, and Analog voltage | | **Accuracy** | ±0.2% F.S. (Full Scale) | | **Power Supply** | AC Adapter (100-240V) or internal rechargeable battery | --- ### 3. Electronic Interfaces and Connectivity The FRTS-AA-R is designed to integrate into automated testing environments through the following electronic connections: 1. **USB Port:** Used for high-speed data logging to software like *Force Recorder*. 2. **I/O Connector:** Allows the device to communicate with external machinery (e.g., stopping a motor if a force limit is reached). 3. **Analog Output:** Provides a ±2V DC signal proportional to the applied force, useful for oscilloscope analysis. --- ### 4. Circuit Protection & Logic * **Overload Protection:** The internal circuitry triggers an alarm and a physical stop signal when force exceeds 110% of the rated capacity. * **Peak Hold Logic:** Electronic memory registers the maximum force value (compression or tension) during a test cycle. * **Tare Function:** Digital zero-adjustment to compensate for the weight of attachments/probes.
