AI-TEK INSTRUMENTS 70085-1010-405 PASSIVE SPEED SENSOR

AI-Tek 70085-1010-405 variable reluctance sensors are essential for control and protection circuits. 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.

Advantages of these sensors include:

• Great reliability
• Easy installation
• No moving parts or contacts resulting in a long lasting sensor
• Self-powered operation
• Large assortment of shapes and sizes
• Simple alignment
• Sensor can be designed for almost any environment

Magnetic Sensor Selection
The following information is supplied for assistance in selecting the proper sensors for your
particular applications. One of the fundamental questions to be answered is, “Will there be enough
sensor output voltage at the lowest operating speed?”
The sensor output voltage depends on:
• Surface Speed - speed target passes pole piece
• Gap - distance between target and pole piece
• Target Size - geometric relationship of pole piece and target
• Load Impedance - connected to sensor
The surface speed of a gear depends upon its diameter and RPM. Surface speed is expressed in
terms of inches per second (IPS).
Surface Speed (IPS) = RPM x Outside Dia. (in.) x π
60
There is an optimum pitch (or tooth size) to
obtain the highest possible output from a sensor,
but this is seldom necessary. Figure 4 illustrates
the relationship of tooth size and spacing for
optimum magnetic sensor output. Using a fine
tooth gear, relative to a large pole piece diameter
sensor, results in a lower generated voltage
because the flux also passes into adjacent teeth,
resulting in a lower total flux variation.
