Maretron PTS-0-3PSI-02 Submersible Pressure Transducer 0-3 PSI

The Maretron PTS-0-3PSI-02 is a submersible pressure transducer designed for precise tank level monitoring in marine applications. This low-pressure sensor operates in the 0-3 PSI range and connects directly to an NMEA 2000® network via a Maretron FPM100 Fluid Pressure Monitor, providing accurate fluid level measurements for a variety of liquids including diesel, gasoline, water, hydraulic fluid, and DEF.

Key Features:

• 0-3 PSI operating range with ±0.3% full-scale accuracy at 25°C
• 316L stainless steel body and diaphragm for corrosion resistance
• 17-foot (5.18m) cable with integrated vent tube for gauge pressure sensing
• 4-20 mA current loop output, loop powered from 8-28 VDC
• Measures water depth up to 83.1 inches, diesel up to 101.3 inches, gasoline up to 110.8 inches
• Compatible with diesel, DEF, gasoline, hydraulic fluid, kerosene, motor oil, and fresh/salt/waste water
• Wide operating temperature range: 14°F to 158°F (-10°C to 80°C)
• Fast 150ms response time with 0.05% full-scale repeatability

Installation:

The transducer mounts through a standard 5-hole SAE J1810 fitting at the top of the tank. Installation can be accomplished either with or without a restraining tube (TFT-5H sold separately). The included mounting plate with cord grip secures the cable while the transducer rests at the lowest point of the tank. The two-wire connection (red to positive, black to negative) interfaces directly with the FPM100's pressure monitoring channels.

Configuration:

Configure connected channels using a Maretron DSM Series Display (firmware 1.4.7 or higher) or N2KAnalyzer software (version 1.4.19 or higher). The sensor features a ±1.0% total error band over the compensated temperature range and maintains ±0.2% non-linearity and hysteresis.
