Figure 1 shows an example MGP260 probe ball valve installation. The figure highlights
the correct wiring routes and shows the recommended installation depth and orientation. An
external pressure measurement instrument (item 5) is shown as an example of pressure
compensation input options: for a description of alternative options, see Pressure compensation input options.
CAUTION Always use a separate cable
for the (Ex ia) external pressure or temperature sensor input wiring (1), and make sure the
wiring remains separated from the terminals and wiring (2) on the other side of the metal
barrier (3) on the component board.
CAUTION Make sure the installation valve and threads are
appropriate from the valve specifications. The correct thread type in which to install MGP260
probes is 1.5" female NPT. Installing into any other thread type can damage the
equipment and compromise the leak tightness of the connection. If unsure, verify the thread
type with a 1.5" NPT thread gauge.
CAUTION Note that the pressure
compensation input must be set up in order to receive accurate measurements. For pressure
input options, see Pressure compensation input options.
