Maretron Submersible Pressure Transducer 0-3 PSI

Description:

Submersible Pressure Transducer 0-3 PSIMaretrons submersible pressure transducers indicate 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, and 2) with a restraining tube.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.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 or focus tube (sold separately, Maretron part number TFT-5H).Pressure Transducer MountingConnect the two wires of the pressure transducer to a free pressure monitoring channel. Connect the red wire from the pressure transducer to the channel's positive (+) terminal 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.Use a Maretron DSM Series Display (firmware 1.4.7 or higher) or a PC running Maretrons N2KAnalyzer software (version 1.4.19 or higher) to configure the connected channel(s) on the FPM100.Supply power to the NMEA 2000 network and verify that the pressure channel indicates a valid pressure reading.Specifications:Operating Range: 0 to 3 PSI (0.207 bar)Depth Range (Water): 83.1 (2.11 m)Depth Range Diesel (820 kg/m3): 101.3 (2.57 m)Depth Range Gasoline/Petrol (750 kg/m3): 110.8 (2.81 m)Cable Length: 17 ft (5.18 m)Sensor Type: Gauge (Vent Tube)Output: 4 20 mA current loop, loop poweredExcitation Voltage: 8 VDC to 28 VDCCompatible Fluids / Gases: Diesel, Diesel Exhaust Fluid (DEF), Gasoline/Petrol, Hydraulic Fluid, Kerosene, Motor Oil, Fresh Water, Sea Water, Waste WaterOperating Temperature: 14 degrees F to 158 degrees F (-10 degrees C to 80 degrees C)Storage Temperature: -4 degrees F to 176 degrees F (-20 degrees C to 80 degrees C)Accuracy: 0.3% Full Scale typ. at 25CTotal Error Band (TEB): 1.0% Full Scale typ.
