The Echo® Wireless Vibration Sensor is a stand

alone, battery powered, industrial vibration sensor.

At the default setting of three measurements per

day (user programmable) battery life approaches 10

years. A Raw Vibration (RV) output version includes

an integral connector that can be used with an

optional cable and a standard vibration data

collector for fault analysis. The sensor can be programmed via RS-232 to set the transmission

(collection) interval and a Residual Vibration Level (RVL) if desired. Echo® has an LED that

provides visual feedback on the status of the sensor, including: on, off, measuring,

transmitting, or changing states. The sensor has an embedded magnetic switch and can be

activated or deactivated by holding a strong magnet next to the sensor. Upon activation, the

sensor makes and transmits a set of measurements.

Vibration System

The Echo® Wireless Vibration Sensor and the EchoPlus® Wireless Junction Box make the set of overall vibration

measurements, listed below, that are sure to provide early warning of most common machine faults. In addition to

these measurements, Echo® provides accurate battery status. Using a user programmable vibration threshold,

Echo® can detect if the machine is not running, and if not, skip a measurement to conserve battery power. It also

has an optional Raw Vibration Output (requires optional Model 070A86 cable) for use with a portable data collector.

Introduction

 RMS Velocity - for “balance-of-plant” faults such as unbalance, misalignment, and flow problems

 RMS Acceleration - for higher frequency faults and high frequency energy (HFE) such as high speed

gear mesh, broken rotor bars, and loss of bearing lubrication

 True Peak Acceleration - for bearing, gear, and impulsive faults, including looseness

 Crest Factor – for fault severity indication
