WARNING – Maretron submersible
pressure transducers are not
approved for use with gasoline. If you wish to use the FPM100 to monitor
pressures or levels of gasoline, you must obtain a pressure transducer that
is approved for use with gasoline. |
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 white wire from the pressure transducer
to the positive (+) terminal of the channel and connect the brown 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.

4.
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.
