The IPX II Series Smart Pressure Transmitter housing has two “feet” used for mounting on a flat
surface or on a pipe using a u-bolt pipe mounting bracket, see Figure 7-1.
The optional 2” Pipe Mounting Bracket kit can be supplied with the process electronics housing. This
mounting bracket can be set-up in a number of different orientations. The metal plate is attached to
the process housing with the kit’s enclosed hardware.
To remove the cover of the IPX II in a hazardous location the power to the transmitter
must be off. With the Intrinsically Safe product, galvanic barrier limits the power so it is
safe to remove cover.
In addition, if the LCD display option is utilized, the electronics inside the housing can be rotated in
90o intervals. To do this remove the two 6-32 machined screws, rotate the electronics to the required
position, and replace the two machined screws. Note the position of the screws may change
depending on the position of the electronics module.

The weatherproof housing has two 3/4” female NPT conduit entries (one is used for the pressure
sensor input). These can be used to mount the housing directly onto the 3/4” male NPT ends of rigid
conduits. Alternatively, a union coupling can be placed between the weatherproof housing and the
wiring from the signal source.

Terminals 1 and 3 are the 4 to 20 mA output terminals. Terminal 2 is not used. These are normally
connected to the corresponding polarity terminals of the power supply of the current loop. Refer to
Figure 7-2 for the terminal connections arrangement.
