Sensor Components – UltraRAE 3000+
The sensor module is made of several components and is attached to the lamp-housing unit as
shown below.
No. Description Part Number No. Description Part Number
1 Inlet probe assembly 023-3012-000 7 Sensor module assembly* 023-3005-X00
2 O-ring, 35mm x 2mm 8 PID sensor 023-3010-001
3 Porous metal filter 9 Rubber adapter
4 Lamp 1/2" (9.8eV) 050-0020-000 10 Tube adapter assembly 059-3015-000
5 Sensor body assembly Filter and O-ring kit 023-3009-000
6 THP (temperature, humidity) sensor module* 023-3011-000
* These parts are service restricted
Note: The cleaning procedure is not normally needed. Clean the PID sensor module, the lamp
and the lamp housing only when one of the following has happened:
1. The reading is inaccurate even after calibration.
2. The reading is very sensitive to air moisture.
3. A chemical 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.
