Passive Magnetic Speed Sensors
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
Due to their flexibility, you will find Al-Tek variable reluctance sensors in everything from low-cost consumer products to highly-accurate automotive engine ignition systems to flight-worthy aircraft engine controls.
