3.2.6. Speed Sensor Mounting Considerations

The sensor should be secured in a rigid mount. Normal machine vibration should

not affect the accuracy of the instrument. However, any relative motion, caused

3.2.6.1. Speed Sensor Types

AI-TEK offers a wide variety of speed sensors that are compatible with the

tachometer instruments. There are also other sources of speed sensors that are

compatible with AI-TEK tachometers.

3.2.6.1.1. Active Sensors

Active sensors require power to operate and the output is usually a digital

square-wave. They are necessary for low and zero speed applications.

Sensing technologies are typically Hall effect but also may be Magneto

Resistive.

3.2.6.1.1.1. Single Channel

Usually 3 wires for connection; power, ground and digital signal

output.

3.2.6.1.1.2. Dual Channel / Bi-Directional

Usually 5 wires for connection; power, ground, two digital signal

outputs and direction logic. These sensors can determine speed and

direction of a rotating target.

3.2.6.1.2. Passive Sensors

Passive sensors require no external power to operate. Power is generated

internally during operation. Typically one output only with two signal

wires for connection.

by a loose sensor or vibrating mount between the sensor and the target can
