Figure 25: Typical PID Sensor Location
PID Sensor & Sensor Adapter
The PID sensor is a cylindrical sensor with a diffusion opening on the front
and 3 pins on the back. It is plugged into a sensor adapter with a 5 wire cable
that terminates in a 5-position connector. The connector plugs into a PID sub
PCB (see description below) that is installed on the main PCB. The sensor
adapter allows installation of the PID sensor into the PID flow chamber. The
sensor adapter is held in the PID flow chamber with two O-rings which also
seal around the sensor adapter.
PID Sub PCB
The PID sub PCB is a circuit board that is installed on the main PCB in one
of the 3 sub PCB positions when a PID sensor is used with the EAGLE 2.
The PID sensor adapter connects to the sub PCB with a 5-position connector.
The sub PCB plugs into the main PCB and is held in place with a screw/flat
washer/lock washer. There are no user serviceable parts on the PID sub PCB.
PID Probe
Several of the gases that can be monitored with a PID are easily absorbed in
the EAGLE 2’s standard sample hose and standard probe. One example of
this is styrene. Because of this, RKI Instruments, Inc. recommends that you
