Pressure transducer 0 to 5 psi - 4-20 mA

The transducer outputs an analog 4-20 mA signal. This signal type is known for its robustness and ability to transmit data over long distances with minimal interference.

The 4-20 mA signal is an industrial standard for its reliability. It allows precise data transmission over long cable lengths with minimal signal loss and is less sensitive to electromagnetic interference, which is crucial in a marine environment.

This transducer is manufactured by Raymarine.

The part number or model number of this pressure transducer is PT-0-5PSI-01.

No, the transducer itself generates a 4-20 mA signal. To integrate it into an NMEA 2000 network, it must be connected to a suitable NMEA 2000 interface module, such as the Maretron FPM100 (Fluid Pressure Monitor) or the Maretron CLM100 (Current Loop Monitor).

To convert the 4-20 mA signal from the transducer into NMEA 2000 data, it is recommended to use a module such as the Maretron FPM100 (Fluid Pressure Monitor) or the Maretron CLM100 (Current Loop Monitor). These modules enable centralized display of the data on NMEA 2000-compatible navigation displays.

Yes, this transducer can be used with any monitoring system capable of accepting and interpreting a 4-20 mA analog input signal. If the target system is NMEA 2000-based, a 4-20 mA to NMEA 2000 interface module will be required.

Yes, once the transducer signal is converted to NMEA 2000 via a compatible interface module (such as the Maretron FPM100 or CLM100), the pressure data can be displayed on Raymarine multifunction displays compatible with NMEA 2000.

The transducer itself is powered by the monitoring module to which it is connected, which in turn is compatible with standard marine electrical systems (typically 12V or 24V). The transducer's direct supply voltage is not specified but depends on the interface module used.

The transducer uses wiring for a 4-20 mA current loop. This typically involves a two-wire connection (power and return signal) to a monitoring module or converter that will provide the required power and read the pressure signal.

The product documentation does not specify the inclusion of mounting accessories. Transducers are commonly sold without them, requiring fittings or mounts suited to the vessel’s specific fluid system.

The transducer must be connected to the pipe or tank whose pressure is to be measured. This is typically done via a standard threaded fitting, whose size must be compatible with the vessel's plumbing system.

Yes, it is important to ensure the transducer is installed in a location protected from physical shocks, excessive moisture, and vibrations. Electrical connections must be watertight and secure to prevent corrosion and false contacts, ensuring long-term reliability.

4-20 mA pressure transducers are typically factory-calibrated. However, the monitoring module or NMEA 2000 converter to which it is connected may require configuration or calibration to correctly interpret the 4-20 mA range based on the specific pressure (0-5 psi in this case) and display it accurately.
