## Beschreibung

#### **KUS Marine Coolant Temperature Sensor – Precise Engine Temperature Measurement for Inboard and Outboard Engines**

Prevent major engine damage caused by unnoticed overheating! The original **KUS coolant temperature sensors** continuously measure the thermal load directly within the internal cooling circuit of your boat’s engine. They convert temperature readings into the standardized analog resistance range of **300 to 23 ohms**. This makes these sensors the precise, reliable partners for all analog and digital KUS coolant temperature gauges (40–120°C) at your helm.

The extremely wide range includes metric and imperial threads as well as various shaft lengths to ensure a perfect fit in engine blocks from well-known manufacturers (e.g., Volvo Penta, Yanmar, MerCruiser, Yamaha, Mercury). The housings, made of high-purity marine brass, guarantee excellent thermal conductivity for lightning-fast response times in the event of thermal issues.

#### 📐 **A direct comparison of the 4 KUS sensor types:**

Please measure the thread, the sensor diameter (Ø), and the required shaft length (L1) on your engine block before purchasing:

- **Type I & Type II (Standard):** Classic analog temperature sensors without an additional integrated alarm contact. Type II features an extended housing.
- **Type III (Combination Sensor with Warning Contact):** These models have a 2-pin connector. They provide a continuous clock signal AND, when the limit temperature is reached (95°C, 98°C, or 107°C, depending on the variant), close an internal switch to activate a separate warning buzzer or an alarm LED.
- **Type IV (Special Dimensions / NPT):** Optimized probe lengths with American NPT tapered threads for U.S. engine systems.

---

#### **Advantages & Technical Highlights at a Glance:**

- **Highest signal precision:** Precisely calibrated to the KUS characteristic curve (approx. 300 ohms at 40°C to 23 ohms at 120°C) for an absolutely flicker-free digital or analog display.
- **Rugged marine brass:** Completely corrosion-resistant against hot coolant, antifreeze, engine oils, and salty bilge moisture.
- **Fully encapsulated, IP67 protection rating:** The connector head is completely sealed against dust and water—providing maximum protection against leakage currents and oxidized contacts.
- **Universal compatibility:** Can be used without restriction in all **12-volt and 24-volt** onboard systems.
