4.4 Combination Master - Slave
In principle, any sensor combination within the instrument series is
allowed. The following requirements must be fulfilled:
•
Configuration, Master sensor suitable for electronic differential
pressure
•
Pressure type is identical for both sensors, i.e. relative pressure/
relative pressure or absolute pressure/absolute pressure
•
Master sensor measures the higher pressure
•
Measurement setup as shown in the following chapters
The measuring range of each sensor is selected such that it fits the
measuring loop. For this, the max. recommended turn down must be
noted. See chapter "
Technical data
". It is absolutely necessary the the
measuring ranges of Master and Slave correspond.
Measurement result = Measured value of Master (total pres-
sure) - measured value of Slave (static pressure)
Depending on the application, individual combinations can result, see
following examples:
