Submersible Pressure Transducers
Maretron’s submersible pressure
transducers are used for indicating tank levels and can be installed directly
in the tank. Please follow these instructions to mount and connect a submersible
pressure transducer to an NMEA 2000® network via a Maretron FPM100 Fluid
Pressure Monitor. Maretron recommends one of two methods for mounting a
submersible pressure transducer in a tank: 1) without a restraining tube (shown
on left side of Figure 1) and, 2) with a restraining tube (shown on right side
of figure 1).
1.
The submersible pressure
transducers are designed for a tank with a 5-Hole SAE J1810 fitting at the top.
Install the mounting plate with cord grip onto the transducer cable, with the
rounded hex section of the cord grip facing away from the transducer.
2.
Lower the pressure transducer into
the tank such that the transducer lies at the lowest point of the tank and
tighten the cord grip to secure the cable. On a tank with a flat bottom, the
transducer may slide from side to side with the motion of the vessel but will
not rotate due to the stiffness of the cable. It is also possible to mount the
pressure transducer inside a restraining tube or focus tube (sold separately,
Maretron part number TFT-5H). Please refer to Figure 1 for examples.

3.
Connect the two wires of the
pressure transducer to a free pressure monitoring channel as shown in Figure 2
below. The diagram shows a connection to FPM100 channel #0, but connections to
other channels are similar. Connect the red wire from the pressure transducer
to the positive (+) terminal of the channel and connect the black wire from the
pressure transducer to the negative (-) terminal of the channel. The example in
Figure 1 shows the pressure transducer connected to switch channel 0 with the white
wire connected to “P0+”, and the brown wire connected to “P0-”. Submersible pressure
transducers have a small plastic vent tube in the connecting cable.
Care must be
taken not to kink or block this tube or pressure readings will be inaccurate.

Use a Maretron DSM Series Display (firmware
1.4.7 or higher) or a PC running Maretron’s N2KAnalyzer software (version 1.4.19
or higher), to configure the connected channel(s) on the FPM100.
