The **FRTD-R-F0-P** is a high-precision, industrial-grade **Resistance Temperature Detector (RTD)** sensor. It is primarily used in applications requiring accurate temperature monitoring where physical space is limited and environmental robustness is necessary. ### 1. Technical Specifications The electrical and mechanical characteristics are summarized in the table below: | Feature | Specification | | :--- | :--- | | **Sensor Type** | RTD (Resistance Temperature Detector) | | **Element Material** | Platinum (Pt) | | **Base Resistance** | 100 Ohms at 0°C (Pt100) | | **Tolerance Class** | Class B (DIN EN 60751) | | **Temperature Range** | -50°C to +200°C (Standard Application) | | **Connection Type** | 2-wire / 3-wire configurations available | | **Lead Wire Material** | Fluoropolymer (Teflon) insulation for chemical resistance | --- ### 2. Key Electronic Components & Design The "electronic" functionality of the FRTD-R-F0-P relies on the physical properties of platinum: * **Thin-Film Element:** The core is a thin layer of platinum deposited onto a ceramic substrate. This provides high stability over time compared to thermistors. * **Positive Temperature Coefficient (PTC):** As the temperature rises, the electrical resistance of the platinum increases in a highly linear and predictable manner. * **Insulation & Shielding:** The "F" in the part number often denotes **Fluoropolymer** insulation, which prevents electrical leakage and protects the signals from moisture and corrosive chemicals. * **The "R" Suffix:** Usually indicates a specific ribbon or flat-profile lead design, allowing the sensor to be mounted on curved surfaces or inside tight motor windings. --- ### 3. Connection Diagram (Electrical Interface) When integrating this part into a circuit, it is typically connected to a Wheatstone Bridge or a Constant Current Source. ```cpp // Example: Calculating Temperature from Resistance (Callendar-Van Dusen simplified) float calculate_temp(float resistance) { float R0 = 100.0; // Resistance at 0°C float alpha = 0.00385; // Standard Platinum coefficient return (resistance - R0) / (R0 * alpha); } ``` --- ### 4. Typical Applications * **HVAC Systems:** Monitoring air and fluid temperatures. * **Industrial Automation:** Overheat protection for motors and bearings. * **Medical Equipment:** Precise thermal control in laboratory instruments.
