            "description": "#### **KUS Marine Oil Temperature Sensor / Transmitter Type 3 – Precise Measurement for Engine & Transmission Oil with 120°C Alarm**\n\nEffectively protect your valuable powertrain from thermal overload! The original **KUS oil temperature sensor (Type 3)** continuously measures the exact heat build-up in your engine oil or transmission lubrication system. It converts the temperature values into the standardized analog resistance range of **300 to 23 ohms**. This makes it the perfect, reliable sensor partner for all analog and digital KUS oil temperature gauges (50–150°C) at the helm.\n\nWhat sets the advanced **Type 3 model** apart is that the sensor features an **integrated, separate warning contact (alarm switch)**. As soon as the oil reaches the critical threshold of **120°C**, the contact closes automatically. This allows you to activate a separate red warning light or an acoustic KUS warning buzzer in the cockpit—in addition to the temperature gauge—to prevent an impending loss of the lubricating film in a timely manner.\n\n---\n\n#### ⚠️ **Important note on sensor compatibility & thread selection:**\n\nThis temperature sensor provides the standard KUS characteristic curve of approximately 300 ohms at 50°C to 23 ohms at 150°C. Please select the exact thread size for your engine block or marine transmission from the drop-down menu above:\n\n- **M14 x 1.5 thread** (metric fine-pitch thread, integrated 120°C alarm)\n- **Thread M16 x 1.5** (metric fine thread, built-in 120°C alarm)\n- **3/8\" - 18 NPT** (American tapered pipe thread, built-in 120°C alarm)\n\n---\n\n#### **Advantages & Technical Highlights at a Glance:**\n\n- **Integrated 120°C warning contact:** Maximum motor protection through simultaneous analog measurement and visual/audible alarm triggering (2-pin connection).\n- **Robust brass housing:** Excellent thermal conductivity for extremely fast response times during sudden temperature spikes, as well as absolute resistance to aggressive, hot oils and chemicals.\n- **Fully encapsulated IP67 protection class:** The sensor head and connection contacts are completely dust- and watertight—optimally protected against splashing water, oil, and bilge moisture.\n- **Universal marine use:** Fully compatible with all engine oils, transmission oils, shaft lubricants, and hydraulic fluids in 12-volt and 24-volt onboard systems.\n\n---\n\n#### 🛠️ **Accessory tip from Tenten-Boats:**\n\nDon’t forget the right gauge! Order the visually perfectly matched, saltwater-resistant **KUS analog oil temperature gauge (52 mm)** right along with it to ensure seamless lubricant monitoring in your cockpit.\n\n---\n\n#### **Technical Data (Specifications):**\n\n**Property**\n**Specification / Value**\n\n**Manufacturer / Brand**\nKUS\n\n**Sensor Type**\nType 3 (Analog Measurement + Digital Alarm Contact)\n\n**Output Signal (Resistance)**\n300 – 23 ohms Characteristic curve (KUS temperature standard)\n\n**Measuring Range**\n+50°C to +150°C\n\n**Alarm threshold**\n120°C ± 3°C (integrated warning contact)\n\n**Housing Material**\nHigh-quality, thermally conductive marine brass\n\n**Protection rating**\nIP67 (waterproof and dustproof at the connector head)",
