13 RMS measurement
13.1 Function
♦ The RMS value (Root Mean Square) is identical to the effective value of
a vibration signal (AC signal). Mathematically speaking it is the square
root of the quadratic average value of the signal and, as a result, is a
measure of the energy content of a vibration.
♦ The RMS measurement is an optional signal path component. As a
configuration interface, it also contains a group of parameters necessary
for the setting.
♦ The physical unit of the RMS measurement is determined by the
preceding components in the signal path, especially through the sensor
/ Sensor (A/B) block.
♦ The RMS value to be calculated is formed over an adjustable averaging
time. New measurements are available only after the averaging time
has run.
♦ The current measurement can be displayed using the User-terminal.
♦ The current measurement is also available as an analogue DC output
signal for peripheral electronic equipment.
♦ The current measured value can be read through the COM-interface of
a downstream OPC-server.
♦ The RMS measurement can be monitored for limit setpoint violation by
one or more Monitor blocks.
