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.
