Data collector instrument with integral speed sensor
First Claim
1. A data collector, comprisinga housing, a vibration signal input on said housing, an analog to digital converter within said housing connected to said vibration signal input, converting a vibration signal received at said vibration signal input to a digitized vibration signal, an optical system within said housing, said optical system receiving light from outside said housing, a receiver circuit converting said received light to a digital signal, and a digital signal processing circuit connected to said analog to digital converter and said receiver circuit, and receiving, storing or processing said digitized vibration signal and said digital signal converted from said received light, in real time, for the purpose of predictive maintenance, whereby the data collector is an integrated device with analog and digital signal processing and an optical system.

Abstract
A data collector having an integrated laser tachometer. The data collector includes, within a housing that can be held by a single hand, circuitry for receiving a vibration signal to be digitized, as well as an optical system for receiving light from outside said housing to be converted to a digital tachometer signal. Digital signal processing circuits within the housing receive, store or process the digitized vibration signal and/or the digital tachometer signal, for the purpose of predictive maintenance. The housing of the data collector also holds a display and input keys, so that an operator may use the same hand for holding and controlling the data collector, and for holding the integrated laser tachometer. This frees a hand for holding an accelerometer or for other purposes. Use of a data collector with an integrated laser tachometer is thus substantially more convenient than using a data collector with a separate, nonintegrated laser tachometer attachment.
