This fuel differential pressure sensor is designed for accurate fuel system pressure monitoring, supporting gas, liquid, and steam applications. With ±0.075% accuracy, 4–20mA two-wire output, IP66 protection, and a 12–36V DC supply, it delivers stable performance in industrial environments.
Hardware & Industrial Environmental Adaptability
- The smart display head of this fuel differential pressure sensor supports the HART protocol, integrating fault self‑diagnosis and three‑key local onsite operation. Full‑isolation protection circuit simplifies configuration while securing stable transmitter operation.
- Rated at IP66 protection grade, the cast‑aluminum housing delivers outstanding corrosion‑resistance and anti‑aging capacity for long‑lasting rugged field deployment.
- Robust stainless‑steel electrical connector upgrades overall protection performance with anti‑fatigue characteristics, well‑suited for diverse severe industrial environments.
- Adopts a heavy‑duty 304 stainless steel nitrogen‑pressurized pressure base for easy pressure tapping; the base brings excellent corrosion resistance and firm mechanical structure for field installation.
Core Measurement Performance
- The fuel differential pressure sensor is built with an imported MEMS monocrystalline silicon diffusion‑silicon sensing chip, achieving high‑precision pressure reading, rapid signal response, and superior long‑term operational stability.
- Equipped with a dual‑overpressure protection diaphragm, this differential pressure transmitter absorbs mechanical impact, safeguards the inner sensing element, and maintains dependable performance amid frequent pressure fluctuations.

Wiring Diagram
Q1: Does the fuel differential pressure sensor support HART communication?
A1: Yes. The differential pressure sensor smart display head supports the HART protocol, enabling digital communication for parameter configuration, device diagnostics, and measurement monitoring.
Q2: Can the fuel differential pressure sensor measure liquids?
A2: Yes. The differential pressure sensor is designed for universal measurement of gas, liquid, and steam, provided that the measured medium is compatible with the sensor's wetted materials and installation conditions.
Q3: What is the power consumption of this differential pressure sensor?
A3: The differential pressure sensor operates from 12–36V DC and has a power consumption of ≤0.5W, making it suitable for low-power industrial instrumentation systems.
Tips: Can this differential pressure sensor measure negative differential pressure?
Yes. The differential pressure sensor supports negative pressure measurement within the corresponding differential pressure range. This allows it to monitor pressure differences where the pressure on one side is lower than the reference side.
