PT-V-0-1BAR-01 (Vacuum to 1 Bar)
Pressure Transducer
|
WARNING – The Maretron pressure transducer
PT-V-01BAR-01 is not approved for
use with gasoline. If you wish to use the FPM100 or CLM100 to monitor
pressures or levels of gasoline, you must obtain a pressure transducer that
is approved for use with gasoline. |
Instructions
Please follow these instructions to connect the PT-V-0-1BAR-01
pressure transducer to the NMEA 2000® network via a Maretron FPM100 (Fluid
Pressure Monitor) or the CLM100 (Current Loop Monitor). The wiring diagram
appears in Figure 1 below. The diagram shows a connection to channel #0, but
connections to other channels are similar.
1.
Please refer to the FPM100 or
CLM100 User’s Guide for detailed information on selecting a mounting location
for the pressure transducer and for further configuration details.
2.
All Maretron external pressure
transducer assemblies are equipped with a ¼” NPT male threaded fitting. Install
the pressure transducer to a ¼” NPT female fitting on the system or tank to be
monitored with a maximum torque of 133 to 177 in-lbs
(15 to 20 Nm). If you are monitoring a system where pressure spikes or
transients will occur, or where the pressure will exceed the maximum pressure
rating of the pressure transducer, install a Pressure Snubber (PT-SNUB-01) onto
the system being monitored first, then install the pressure transducer to the
female port on the pressure snubber.
3. Connect
the two wires of the pressure transducer to a free pressure monitoring channel.
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-”. Pressure transducers of “Gauge”
type allow atmospheric pressure to the sensor through the connecting cable.
Take care to not allow the end of the cable with the tinned wire leads to be
exposed to moisture, or the sensor may become damaged due to corrosion. If the
area where the end of the cable is located might have moisture present, the use
of 1) a waterproof junction box with cable glands and a PTFE vent or 2) a
desiccant cartridge is highly recommended. Running the cable through a cable
gland will not affect its ability to allow atmospheric pressure through the
cable into the sensor.
4.
Supply Power to the NMEA 2000®
network to verify that the pressure channel indicates a valid pressure reading.
5.
Using either a Maretron DSM Series display
(firmware 1.4.7 or higher) or by using a Maretron gateway, such as the USB100,
paired with a Windows® PC running the Maretron N2KAnalyzer®
software to configure the FPM100 or CLM100 and connected channels.
