Fuel oil pressure transducers measure the pressure of fuel within the fuel system, ensuring optimal engine performance.

They convert mechanical pressure into electrical signals for monitoring and control by the engine management system.

These transducers are critical for maintaining fuel efficiency, safety, and compliance with operational standards.

Fuel Oil Pressure Transducers:

- Size: Typically 1/4" NPT or 1/2" NPT threaded connections

- Grade: Industrial-grade, marine-grade, or aviation-grade depending on application

- Viscosity Compatibility: Suitable for fuels with viscosities ranging from 1.3 cSt to 700 cSt

- Buoyancy: Not applicable (solid-state sensing)

- Material: Stainless steel (316L), brass, or aluminum housing; elastomer seals (Viton, Nitrile)

- Pressure Range: 0-100 psi to 0-10,000 psi (depending on model)

- Output: 4-20 mA, 0-5 VDC, or 0-10 VDC

- Temperature Range: -40°C to 125°C (-40°F to 257°F)

Fuel Systems:

- Size: Varies by application (e.g., automotive, marine, aerospace)

- Grade: ASTM D975 (diesel), ASTM D910 (aviation), ISO 8217 (marine)

- Viscosity: 1.9 cSt (Jet A) to 700 cSt (heavy fuel oil)

- Buoyancy: Relevant for float-type fuel level sensors

- Material: Aluminum, stainless steel, or reinforced plastics for tanks; rubber or synthetic hoses

- Operating Pressure: 10-100 psi (low-pressure systems) to 3,000+ psi (common rail diesel)

- Temperature Range: -40°C to 150°C (-40°F to 302°F) for most systems
