The **FRTD-S-CB-R** is a specific electronic component typically categorized under temperature sensing and control accessories. Specifically, it is a **Flexible Resistance Temperature Detector (RTD)** sensor probe, often used in industrial automation, HVAC, and laboratory environments. ### 1. Technical Specifications The part number breaks down into specific physical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Sensor Type** | RTD (Resistance Temperature Detector) | | **Element Type** | Platinum (usually Pt100 or Pt1000) | | **Form Factor** | Flexible / Ribbon style (Thin-film) | | **Lead Wire Configuration** | 2, 3, or 4-wire (depending on precision requirements) | | **Mounting** | Self-adhesive or mechanical clamp (indicated by "CB" suffix) | --- ### 2. Key Electronic Characteristics #### A. The RTD Element The "heart" of the component is a thin-film platinum resistor. Its electrical resistance increases linearly with temperature. * **Accuracy:** High stability over long periods compared to thermocouples. * **Response Time:** The "Flexible" nature (S-style) allows the sensor to have low thermal mass, meaning it reacts very quickly to temperature changes on the surface it is attached to. #### B. Connection Interface ("CB-R") The suffixes in these parts usually denote the termination and wiring: * **CB:** Often refers to a specific connector block or a "Connector Boot" for environmental protection. * **R:** Typically signifies a "Right-Angle" orientation or a specific "Ribbon" lead style to save space in tight electronic enclosures. --- ### 3. Typical Applications Because of its flexible, flat profile, the FRTD-S-CB-R is used where traditional cylindrical probes cannot fit: 1. **Battery Pack Monitoring:** Measuring the surface temperature of Li-ion cells. 2. **Semiconductor Equipment:** Monitoring heat sink temperatures. 3. **Medical Devices:** Integrated into wearable or contact-based diagnostic tools. 4. **Aerospace:** Surface mounting on curved fuselage or engine components. --- ### 4. Circuit Integration Example To read data from this component, it is typically connected to a Wheatstone Bridge circuit or a dedicated RTD-to-Digital converter (like the MAX31865). ```cpp // Example: Concept logic for reading an RTD value float resistance = readADC(RTD_PIN); float temperature = (resistance - 100.0) / 0.385; // Standard Pt100 DIN coefficient ```
