2.3.2 Pressure Transducer
The pressure transducer measures the system pressure at the point that the
eluent flows from the pump head outlet check valve. Pressure readings
indicate that the pumping system is delivering smooth, accurate flow.
Pressure readings can be monitored from Chromeleon or Chromeleon
Xpress.
The system pressure should remain consistent (no more than a 3%
difference from one pressure reading to the next). High and low pressure
limits can be used to stop the pump flow if a limit is exceeded. The
pressure limits can be set from Chromeleon (in the Server Configuration
Properties dialog box or in the Chromeleon or Chromeleon Xpress
program).
For troubleshooting information if a pressure limit is exceeded,
see Section 4.7 .
Pulse Damper
Flow output from the pressure transducer continues to the pulse damper,
which smooths minor pressure variations. From there, flow is directed to
the injection valve and then to the remainder of the chromatography
system.
