Pulse Wire Sensor Suits Many Industrial Applications

HARRISBURG, Pa., November 29 - Tyco Electronics recently added pulse wire sensors to its extensive line of passive electronics. Pulse wire sensors can sense rotor positions, serve as revolution counters and detect speed and rotation. The sensor is contactless and requires no external power to operate. Its permanent magnet design generates high output voltages from 3.5 to 4 VDC and requires no voltage amplification for switching electronics.

This product is suitable for applications in flow meters; especially where flow is remotely monitored and batteries are used to power the existing sensor system. With the pulse wire sensor, batteries and scarce system power are not required. The 3.5 to 4VDC generated by the sensor is compatible with integrated circuits that require similar power levels for processing.

Additionally, pulse wire sensors are suitable for motor commutation applications. Since pulse wire sensors have a precise and accurate trigger point, the point at which the pulse is emitted and sensor is activated, the sensor exhibits optimum repeatability. The repeatability of this sensor can help improve motor efficiency in brushless DC motor applications as compared to typical sensors which tend to trigger (process of sending a signal to energize the subsequent set of coil windings) a few degrees from a set-point, this in turn, causes a time delay and either wastes energy or slows down the rotor.

In addition to flow metering and motor applications, designers may use this product in a variety of automation, energy and other machinery applications where sensing of stroke movement, position, and rotation is required.

Pulse wire sensors from Tyco Electronics are suitable for applications with drive frequencies of zero Hz up to 10 kHz. They are highly adaptable to custom applications and have generous mounting tolerances for sensor position and air gap.
