18. Installation & Wiring
Differential pressure
sensors have two
pressure connections
on the back of the
gauge. The diagram
at the left shows the
correct connections
to obtain the desired
type of pressure
measurement.
Gauge-Isolated and
Absolute-Isolated
pressure gauges
have only one
pressure connection.
The SetPoint model
utilizes the multi-
function terminal
strip shown at the
left. This terminal
strip has a NEMA 1
rating. SPDT relays
are not powered by
the gauge internally.
Jumpers from the
24Vdc, 110Vac or
220Vac power
sources can be used
if required.
The Current Loop
model uses a cannon
connector that is
designed to meet
NEMA 4X
requirements. The
diagram at the left
shows the terminal
arrangement.
Wiring schematics for the three and four wire, 4 to 20 mA loops are shown on the following page.
