27.2 PID Sensor & Lamp Cleaning/Replacement
The sensor module is made of several components and is attached to
the lamp-housing unit as shown below.
Inlet Probe Assembly
PN 023-3012-000-FRU
Tube Adapter
Assembly
PN 059-3015-000-FRU
O-ring, 35mm x 2mm
Porous Metal Filter
Lamp 1/2 " (9.8eV)
PN 050-0020-000
Seal Nut
Sensor Detector
PN 023-3010-001
Rubber Adapter
Sensor Components
Note:
The cleaning procedure is not normally needed. Clean the PID
sensor module, the lamp and the lamp housing only if:
1. The reading is inaccurate even after calibration.
2. The reading is very sensitive to air moisture.
3. A liquid has been sucked into the unit and damaged the unit.
Use of the external filter helps to prevent contamination of the sensor.
To access the sensor components and lamp, gently unscrew the lamp-
housing cap, remove the sensor adapter with the gas inlet probe and
the metal filter all together. Then hold the PID sensor and pull it
straight out. A slight, gentle rocking motion helps release the sensor.
Note:
The 10.6eV lamp requires a Teflon O-ring. The 9.8eV and
11.7eV lamps do not require the O-ring.
