4 Installation
4.1 Piping
The ST-565 Series probe can be installed in an inline flow application using the included Pyxis ST-001 Inline
Tee Assembly. The ST-001 offers 3/4” FNPT thread or socket weld adapters with unions for easy installation
and sensor maintenance. To properly install the ST-565 Series probe into the ST-001 Tee Assembly, follow
the steps below:
1. Insert the provided O-ring into the O-ring groove on the tee.
2. Insert the ST-565 Series probe into the tee.
3. Tighten the tee nut onto the tee to form a water-tight, compression seal.

4.2 Wiring
If the power ground terminal and the negative 4–20mA terminal in the controller are internally connected
(non-isolated 4–20mA input), it is unnecessary to connect the 4–20mA negative wire (green) to the 4–20mA
negative terminal in the controller. If a separate DC power supply other than that from the controller is used,
make sure that the output from the power supply is rated for 22–26 VDC @ 65 mA.

NOTE

The negative 24V power terminal (power ground) and the negative 4–20mA ter-
minal on the ST-565 Series probe are internally connected.
Follow the wiring table below to connect the ST-565 Series probe to a controller:
