NOTE
This procedure describes how to replace the pressure sensor.
In case the cable to the sensor shall be replaced as well, please contact your Agilent service representative.
NOTE
Working on connections to the pressure sensor may slightly change the displayed pressure. In case of a pressure offset at ambient pressure, a pressure offset calibration may be run.
-
Remove capillary connections between the pressure sensor and the High Pressure Filter, and between the pressure sensor and the outlet adapter of the secondary pump head, respectively.
-
Remove the screws that fix the pressure sensor to the chassis.
-
Carefully pull out the pressure sensor for about 2 cm. Then unscrew the cable from the pressure sensor.
-
Connect the new pressure sensor to the pressure sensor connector.
-
Fix the pressure sensor to the instrument chassis.
-
Connect the capillary from the pump head outlet to the pressure sensor inlet (1). Connect the capillary from the high pressure filter to the pressure sensor outlet (2). Two arrow signs on the pressure sensor indicate the flow direction.
