The **FRTS-EG-R** is a specialized high-speed, high-precision electronic force sensor (typically part of the Imada Force Recorder series) used for measuring tactile sensations and micro-loads. It is frequently employed in testing the "feel" of buttons, switches, and touch panels. --- ### Key Electronic Components and Specifications The electronic architecture of the FRTS-EG-R is designed to convert physical pressure into a high-resolution digital signal with minimal latency. | Component | Description | Specification | |:---|:---|:---| | **Load Cell** | High-sensitivity strain gauge transducer. | Capacities typically 2N, 5N, or 10N | | **A/D Converter** | Analog-to-Digital converter for signal processing. | High-speed sampling (up to 2000Hz) | | **CPU/Microprocessor** | Manages data calculation and I/O communication. | 32-bit RISC architecture | | **Display Interface** | Internal circuitry for OLED/LCD data visualization. | Real-time graph plotting capability | | **I/O Ports** | Electronic connection points for external control. | USB 2.0, RS232C, and Analog output | --- ### Electronic Features Breakdown #### 1. High-Speed Sampling Circuitry The device utilizes a high-frequency sampling rate of **2000 data points per second (2kHz)**. This is electronically significant because it allows the sensor to capture instantaneous "click" sensations (the sudden drop in force when a dome switch activates) that standard sensors would miss. #### 2. Analog-to-Digital Signal Processing The internal electronics feature a high-resolution delta-sigma ($\Delta\Sigma$) A/D converter. This minimizes electronic noise interference, ensuring that even at very low forces (millinewtons), the data remains stable and repeatable. #### 3. Protection Circuits * **Overload Prevention:** Electronic limiters trigger a warning beep and signal cutoff when the load exceeds approximately 110% of the rated capacity. * **ESD Shielding:** The internal housing is electronically shielded to prevent Electrostatic Discharge (ESD) from interfering with sensitive measurement data. #### 4. Connectivity and Integration The FRTS-EG-R functions as a smart sensor. Its electronic back-end supports: * **USB Power/Data:** Draws power and transmits data via a single cable. * **Trigger Input:** Allows an external electronic signal (like a PLC) to start or stop measurements. --- ### Comparison: FRTS-EG-R vs. Standard Force Gauges | Feature | Standard Gauge | FRTS-EG-R Electronic System | |:---|:---|:---| | **Sampling Rate** | 1000Hz | 2000Hz (Superior for tactile analysis) | | **Noise Floor** | Moderate | Ultra-low (optimized for micro-loads) | | **Software Link** | Basic CSV export | Real-time Force-Displacement-Time integration |
