User Manual
Other
measurement type allows the user to configure an analog channel with
user defined properties within the following system defined constraints.
For detailed information refer to the measurement type
EU has to be one of the predefined engineering units. See the
table above, Analog channel parameter combinations.
The analog measurement type "Other" is specifically intended to
be used in conjunction with the standard 0-10 V or 4-20 mA
process control signaling (signal converters).
Important - Standard 0-10 V or 4-20 mA process control signaling does not
mean that IMx-M can read any possible DC voltage or current in this range. If other
voltage ranges or current ranges are utilized there may be loss of accuracy and
resolution. The specified measurement performance is only guaranteed with either
0-10 V or 4-20 mA signalling.
System defined constraints are found under each properties, if
any.
Sensitivity:
applies to the
Other
channel type only. It allows to specify the sensor
sensitivity as volt or amp ratio.
Math Method:
applies to Casing Vibration channel type only. It determines the method
by which the reference accelerometer signal can be mathematically redefined (via single
integration) as a velocity signal.
EU (Engineering Units):
These are the engineering units for the selected channel. This
has to match the physical sensor type. For example, displacement sensors should have
"um" or "mm", whereas accelerometer sensors should have "g".
Detection:
This is the type of signal rectification that is to be used in processing the
returned signal. This can be set to “RMS” (true Root Mean Averaging), PtP (true Peak to
Peak) or “P” (true Peak to Peak / 2).
Once an analog channel has been initiated with the above
mentioned settings, these initialization settings cannot be
changed. In order to change them, the analog channel has to be
deleted and reconfigured.
