Based on the product code **FRTS-CA-R**, this refers to a specific configuration of a **Force Recorder Test System** (specifically the Food Rheology Tester) manufactured by **IMADA**. This system is designed for high-precision texture analysis and food rheology testing. Below is an explanation of its electronic components and characteristics. --- ### 1. System Overview The "CA" in the model name typically signifies a specialized **Cable or Calibration** set, and "R" denotes the **Recorder** or software-integrated version. The electronic core of this system is a combination of a motorized test stand, a digital force gauge, and data acquisition hardware. ### 2. Key Electronic Components | Component | Function | Technical Detail | | :--- | :--- | :--- | | **Digital Force Gauge** | The "Brain" that senses resistance. | High-speed sampling rate (up to 2000Hz). | | **Load Cell** | Transducer that converts force to voltage. | High precision with low hysteresis. | | **Motorized Stand** | Controls movement via electronic pulses. | Stepper motor with digital speed control. | | **USB/RS232 Port** | Data output interface. | Used for PC connection and software integration. | | **Limit Switches** | Safety electronics. | Prevents mechanical overload or over-travel. | --- ### 3. Electronic Specifications The performance of the FRTS-CA-R relies on several electrical parameters that ensure measurement accuracy: * **Sampling Rate:** Typically **2000 data points per second**, allowing for the capture of rapid changes in food texture (e.g., a "snap" or "crunch"). * **Power Supply:** Generally operates on **100V – 240V AC**, utilizing an internal switching power supply to provide stable DC voltage to the sensors. * **Connectivity:** * **USB Output:** For direct logging into the Force Recorder software. * **Analog Output:** Some versions include a ±2V DC output for integration with oscilloscopes. ### 4. Signal Processing Chain 1. **Deformation:** The probe hits the sample. 2. **Transduction:** The **Strain Gauge** inside the load cell changes resistance. 3. **Amplification:** The internal PCB amplifies the millivolt signal. 4. **A/D Conversion:** An Analog-to-Digital converter translates the signal into a numerical value. 5. **Data Transmission:** The value is sent via USB to the **Force Recorder** software for graphing. --- ### 5. Control Interface The system features an electronic control panel with: * **LCD Display:** For real-time force monitoring. * **Digital Input Keys:** To set travel distance, speed (mm/sec), and force limits. * **Overload Protection:** An electronic circuit that cuts motor power if the force exceeds the sensor's capacity.
