Magnetic rotational speed sensor
AI-Tek
Designed to meet severe industrial, automotive and aerospace environments, Al-Tek speed sensors, will provide reliable, around-the-clock operation for many years under adverse conditions. Our design engineers have paid particular attention to trouble areas such as vibration, shock, extreme temperatures, wet, oily and corrosive atmospheres. Many of our speed sensors are specifically designed for high temperature, high or low speeds, various targets or for precise accuracy and timing applications. Al-Tek uses primarily the two technologies of variable reluctance, and Hall effect to convert motion into an electronic signal. By selecting the best technology for a specific application we can assure years of reliable performance.
Control and protection circuits have relied on variable reluctance technology for years. With few
components and no moving parts, the passive magnetic speed sensors can provide a signal from
the inside of an aircraft engine at temperatures approaching 425°C or from the hub of an automobile
wheel at high shock and vibration. The advantages of these sensors are:
-High reliability
-Simple installation
- Long life due to no moving parts or contacts
-Self powered operation
-Wide variety of shapes and sizes
- Easy alignment
- Can be designed for almost any environment
