The **HTS-72-R/BL** refers to a high-performance **Heated Tube/Hose System** typically used in industrial applications such as gas analysis, emissions monitoring, and hot melt adhesive delivery. The model designation generally indicates a specific diameter, length, and integrated control components. ### 1. Key Electronic Components The electronic architecture of this part is designed to maintain precise temperatures to prevent condensation or material hardening. | Component | Description | Function | | :--- | :--- | :--- | | **Heating Element** | High-grade NiCr (Nickel-Chrome) resistance wire. | Converts electrical energy into heat along the length of the hose. | | **Temperature Sensor** | Usually a **PT100** RTD or a **Type K** Thermocouple. | Provides real-time thermal feedback to the external controller. | | **Thermal Insulation** | Silicone foam or fiberglass sleeving. | Minimizes heat loss and protects the outer jacket from melting. | | **Power Connector** | Multi-pin circular connector (e.g., Amphenol or Harting). | Carries both the 230V/115V power and the low-voltage sensor signals. | | **Over-temperature Switch** | Integrated bi-metal switch (optional). | Acts as a safety cut-out if the temperature exceeds the safe limit. | --- ### 2. Technical Specifications (Typical) While specific configurations vary, the **R/BL** series usually follows these parameters: * **Operating Voltage:** 115V AC or 230V AC (model dependent). * **Temperature Range:** Up to 200°C (392°F) or 250°C for high-temp versions. * **Resistance:** Calculated based on the wattage per meter (W/m) to ensure uniform heating. * **Sensor Calibration:** Standardized to DIN EN 60751 for PT100 elements. --- ### 3. Wiring Configuration The electronic interface is typically divided into two circuits within the cable assembly: ```yaml Pin Connection Example: - Pins 1 & 2: Power Supply (L1 / N) - Pin 3: Ground (PE) - Pins 4 & 5: Temperature Sensor (PT100 or TC) - Pin 6: Shield/Screen (Optional for signal integrity) ``` ### 4. Application Context The **"R/BL"** suffix often signifies specific build features: * **R:** Corrugated outer PA6 (Polyamide) conduit for mechanical protection and flexibility. * **BL:** Basic/Blue series, often denoting a standard interchangeable design for gas sampling probes. ---
