Appendix D: PID Sensors
Overview
The PID (photo ionization detector) sensors are used for applications where
high sensitivity is needed to monitor ppm levels of VOCs (volatile organic
compounds). This appendix describes the EAGLE 2’s PID sensors and
includes instructions to use an EAGLE 2 that has a PID sensor installed. It
also includes instructions to maintain and replace a PID sensor.
Table 13: EAGLE 2 PID Sensor Specifications
Description
Two types of PID sensors can be used with the EAGLE 2, a low range (high
sensitivity) sensor and a high range (low sensitivity) sensor (see Table 13 for
specifications). The PID sensor is installed in a single sensor flow chamber
which is located in the area next to the standard 4-sensor flow chamber. This
area can accommodate up to three single sensor flow chambers. Figure 25
below illustrates a typical PID sensor location in front of the pump. The PID
flow chamber may also be installed in one of the other two sensor chamber
locations depending on the particular version of the EAGLE 2. Some PID
instrument configurations do not include the 4-sensor flow chamber.
