Review THE LEWIS ENGINEERING COMPANY Engine Vintage Warbird Temperature Indicator fits TWIN

The Lewis Engineering 77B46 Twin Engine Warbird Temperature Indicator is a high-performance, precision avionics instrument designed specifically for the needs of warbird and vintage aircraft owners. This temperature indicator is a must-have for pilots who value the safety and reliability of their aircraft, as it provides accurate and real-time information about the temperature of each engine.

The 77B46 is a twin-engine model, meaning it can accommodate two separate engine temperature sensors. This feature makes it an excellent choice for aircraft with multiple engines, as it enables pilots to monitor both engines simultaneously. Each engine temperature is displayed on a separate dial, allowing for easy comparison and quick identification of any temperature anomalies.

The temperature indicator is constructed from robust and durable materials, ensuring that it can withstand the rigors of regular aircraft use. The anodized aluminum case is not only attractive but also resistant to corrosion, while the dial faces are protected by a layer of high-impact acrylic glass. The backlighting system, which can be adjusted for brightness, ensures that the displays remain easily readable in all lighting conditions.

The 77B46 temperature indicator uses advanced temperature sensing technology to provide accurate temperature readings. The sensors are designed to detect both engine coolant and oil temperatures, ensuring that pilots have a complete understanding of their engine's thermal conditions. The temperature readings are displayed in degrees Fahrenheit or Celsius, depending on the pilot's preference.

The installation of the Lewis Engineering 77B46 Twin Engine Warbird Temperature Indicator is straightforward and can be accomplished using standard avionics mounting hardware. The instrument comes with a comprehensive installation guide and is compatible with most standard aircraft wiring configurations. The temperature indicator also includes a built-in warning system, which can be set to alert pilots when engine temperatures exceed predetermined thresholds.

In summary, the Lewis Engineering 77B46 Twin Engine Warbird Temperature Indicator is an essential avionics instrument for warbird and vintage aircraft owners. Its robust design, advanced temperature sensing technology, and easy-to-read displays make it an invaluable tool for ensuring the safe and reliable operation of these historic aircraft. By providing pilots with accurate and real-time temperature information for both engines, the 77B46 helps to minimize the risk of engine damage and ensures that flights are as enjoyable and successful as possible.
