3.7 EXPLANATION OF PRESSURE
TRANSDUCERS
Standard Transducers: The Illustration below
shows the Standard Pressure Transducers included
with each System.
a) Low Pressure Transducer #1 measures the
pressure into the Prefiltration. This is the pressure
exiting from the Booster Pump.
The Pressure Manifold for Low Pressure
Transducer #1 is located inside the System Frame.
b) Low Pressure Transducer #2 measures the
pressure exiting the last Prefilter. This is the
pressure entering the High Pressure Pump.
The difference of pressure registered by Low
Pressure Transducer #1 and Low Pressure
Transducer #2 equates to the amount of line
loss, or pressure loss, across the prefiltration.
As the Prefiltation elements become fouled the
pressure registered by Low Pressure Transducer
#1 increases and the pressure registered by Low
Pressure Transducer #2 decreases.
The Low Pressure Transducer #2 is located on the
HP pump inside the System Frame.
c. High Pressure Transducer #3 measures the
pressure exiting the HP Pump. This is the pressure
entering the RO Membrane Vessel.

The Optional Differential Pressure Transducer #4 (not
shown) measures the pressure between two Prefiltration
components. The difference of the pressure into and out
of a Prefiltration component is the "differential" across
that given Prefilter.
When the System is equipped with two (2) or more
prefiltration components, such as a Commercial Prefilter
and Oil/Water Separator it is helpful to know the pressure
across each of them. Knowing the pressure across each
filter allows the operator to easily diagnose which of the
filters is dirty and requires changing.
The Differential Pressure Transducer will pay for itself
in a very short period of time through less time spent
troubleshooting dirty filter elements.
Pick Up T for Differential Pressure Transducer is
always plumbed in the Feed Line at the appropriate
location by the Installer and connected to the
Differential Pressure Transducer with a 1/4 in. (6.35 mm)
OD Tube by the Installer.
