Emerson AMS Wireless Vibration Monitor, User Manual, Page: 65 / 86

A Specifications and reference data
A.1 Functional specifications
Input Three internal MEMS accelometers oriented in the X-Y-Z direction. The Z
accelometer has the greatest bandwidth and is considered the primary sensor.
The device also has a temperature sensor designed to read the temperature
near the mounting point.
Output Wireless-enabled, linear with temperature or input.
Humidity limits 0–95% relative humidity
Transmit rate User-selectable, 60 seconds to 24 hours.
Measurement Measurement Parameters
The device is capable of measuring and reporting machine health
measurement parameters and generating alerts based on overall vibration in
each axis as well as peak impact measurements in the primary axis and
temperature readings.
Measurement precision
Measurement precision refers to the variability of the same measurement in a
fixed operating environment under steady-state conditions. For vibration, this
value is obtained with statistical measurements with 1 g-peak (9.81 m/s
2
)
input excitation at a frequency of 100 Hz. For temperature, this value is
obtained with statistical measurements at room temperature.
