Honeywell 51404092-200 Aerospace Gauge Pressure Transducer Sensor

Product Overview

The Honeywell 51404092-200 functions as a high-precision, rugged gauge pressure transducer engineered for demanding aerospace and heavy-duty industrial telemetry networks. This sensor monitors fluid or gas line pressure up to 200 psi and transmits dual ratiometric analog and ARINC 429 digital signals directly to flight control computers or DCS data loggers. We deliver this high-grade instrument exclusively as a 100% brand new, factory-original unit to ensure absolute calibration integrity and prevent critical signal drift in extreme operating zones.

Engineering Advantages

• Eliminates Thermal Calibration Drift: Internal solid-state compensation modules maintain an outstanding accuracy profile of $\pm0.2\%$ FS across a punishing $-55\text{ °C to }+125\text{ °C}$ thermal span. This wide-range calibration stability resolves the common issue of signal deviation found in standard commercial transmitters when a machine transitions from sub-zero start-ups to maximum running heat.

• Withstands Severe Kinetic Stress: The mechanical sensor core withstands structural vibration loads up to 40g and isolated shock spikes reaching 100g. This extreme resilience prevents internal piezoresistive element fracturing during deployment on high-vibration aircraft engines or high-pressure hydraulic pumping manifolds.

• Instantaneous Control Loop Feedback: The sensor updates its output register in less than 0.5 ms. This ultra-fast response speed supplies real-time transient spike detection to automated safety shut-off valves, completely neutralizing hazardous over-pressure waves before pipe rupture occurs.

FAQs

• Does the 51404092-200 output both signal types simultaneously?

  Yes. The onboard micro-electronics process and deliver the 0.5–4.5 VDC ratiometric voltage curve and the ARINC 429 digital data stream at the same time. This hybrid capability allows engineers to connect the analog tap to a localized safety indicator while routing the digital signal to the master bus.

• What installation steps protect the physical pressure port threads?

  Field technicians must apply standard anti-seize or thread-lubricant compatible with the processed media before mating the sensor to the pressure port. Use a calibrated torque wrench on the hex flats rather than twisting the upper sensor housing to prevent internal core misalignment.

• Does this sensor require field-level zero or span calibration upon unboxing?

  No. Every 100% brand new Honeywell 51404092-200 arrives fully calibrated and certified from the factory floor. The internal non-volatile memory retains its true 0–200 psi settings, eliminating the need for pre-installation tuning bench tests.
