only measure to its limits, even if the signal is slightly outside of the
measurement range.
• The Square Root property allows the unit to be used in applications in which the
measured signal is the square of the PV. This is useful in applications such as the
measurement of flow with a differential pressure transducer.
• The Linearizer property (linearizer models only) allows the unit to be used in
applications in which the measured signal is non-linear with respect to the
desired PV value. This is useful in applications such as the measurement of
material volume in a round, horizontally mounted tank or vessel with a level
probe.
THE LINEARIZATION TAB
The CSINI8L and CSINV8L modules offer a 100-point per channel linearization function.
LINEARIZER
To use the linearizer function for a given input, its Linearizer property on the configuration
tab must be checked.
• The Channel value selects which input you currently wish to work with, and
isn’t really a property at all.
• The Decimals property is used to allow Crimson to display the engineering units
in the proper resolution. This is only used to display the appropriate resolution
throughout the software, and is not used within the module.
• The Slope property can be used to change the ratio of the PV in relationship to
the sensor reading. This is useful in applications in which the sensor error is nonlinear,
but can still be measured with simple two-point scaling.
• The Offset property can be used to compensate, or shift, the PV value. This is
useful in applications in which the sensor error is non-linear, but can still be
measured with simple two-point scaling.
