14.12.5 Display of sensor amplitudes
The first line of this window contains the actual measured amplitudes of the sensor signals S1 and S2.
Both values should be close to each other or identical (ideal case). The second line shows the excitation
frequency and current.
S1 090 S2 089 mV
112.8 Hz 12.8 mA
Example: The sensors have amplitudes of 90 mV and 89 mV. The excitation current is 12.8 mA and the
actual resonance frequency is 112.8 Hz.
The combination with the raw value display (see chapter 14.1.14 Raw values on page 50) supports the
analysis of all electrical signals between mass flow sensor and transmitter.
