Why use valuable manpower to collect
vibration data on healthy machines? Why
settle for measurements once a month
when you can have them multiple times
daily? Why have people venture into
unsafe areas to collect routine
measurements? Echo® Wireless
Vibration Sensors can safely “look” at the
machine’s health several times per day
and provide immediate notification when
warning or critical levels are reached. This
frees up technical experts, like certified
vibration analysts, for higher value tasks
such as fault analysis.
■Transmits very long distances
■Batteries last up to 10 years
■Eliminates expensive cable runs
■Requires no repeaters, networks, or mesh
■Run stand alone or with junction box
■Stores data in ODBC format
■Easily installed

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

The EchoPlus® Wireless Junction Box is an 8-channel
junction box that instantly converts installed industrial
sensors to wireless operation. This incredibly economical
device periodically powers each sensor, makes the same set
of overall measurements as Echo®, and transmits them
wirelessly. The default transmission interval is 8-hours but
is user programmable. Additionally, it operates as a
standard junction box allowing full data collection with a portable data collector at the box. It can be
powered using either standard 24 VDC or any battery between 6 and 14 VDC. The unit can be used by
itself or in conjunction with an existing junction box by simply jumping wires between them.
