Aerospace pressure sensor UNIK5000F

absolutegaugepiezoresistive

Description
Druck's UNIK5000F is a pressure sensor engineered for oxygen-enriched environments where safety, measurement integrity and long-term reliability are required. Based on the UNIK5000 platform, the UNIK5000F pairs oxygen-compatible wetted materials with piezoresistive sensing and Halocarbon fill fluid selected for oxygen service. The sensor is supplied in a cleanable condition and may be integrated into customer-defined oxygen cleaning processes when required.

Designed for oxygen compatibility
The UNIK5000F has been developed specifically for oxygen applications, incorporating:

• Oxygen-compatible wetted materials throughout the pressure system
• Halocarbon fill fluid suitable for oxygen service
• Cleanable wetted flow paths designed to avoid particle traps and sharp corners
• Calibration performed using dry gas or de‑ionised/pure water only; no oil is used during calibration

High accuracy and stability
The UNIK5000F provides the accuracy and repeatability required by aerospace, industrial gas and clean energy sectors. Key performance data include:

• Pressure range up to 350 bar (absolute and sealed gauge)
• Accuracy up to ±0.04% FS
• Long-term stability typically ±0.05% FS per year
• Frequency response up to 3.5 kHz
• Temperature compensation options from -40°C to +80°C

Applications and use cases
Typical uses include liquid oxygen storage monitoring, ground support equipment (GSE), rocket propulsion testing, launch-pad utilities and oxygen generation facilities — wherever dependable, oxygen-compatible pressure measurement is required for mission-critical systems.

Built on UNIK5000 platform
The UNIK5000F leverages the UNIK5000 family architecture and advanced piezoresistive sensing technology to deliver an oxygen-compatible solution suitable for demanding industrial and aerospace environments.
