Aero-Engine Pressure Sensors (-55~150℃) | Line & Accessory System Measurement for Bench Test & Flight Trials

Most aero-engine test setups use overpriced high-temperature sensors for every measurement point, even when 70% of pressure taps on fuel lines, lubrication systems, bleed air ducts and hydraulic circuits never exceed 120℃ in continuous operation.

Our -55~150℃ pressure sensors purpose-built for these high-volume, non-hot-section points: built to the same vibration resistance and accuracy standards as high-temperature aerospace sensors, but delivered in a fraction of the lead time at 60% lower cost. We also supply fully calibrated matched accelerometers, mounting hardware and remote-install solutions for higher-temperature static/low-dynamic measurements, so you don’t waste budget on over-specified parts or time matching components from multiple vendors.

All test data supports ISO 17025 CNAS traceable calibration for global aerospace test projects.

This model has completed 200+ hour continuous hot-fire test runs across global deployments, with total recorded zero drift of <0.02% FS.
⚠️ Application Limitation Notice: Sensors in this selection guide are designed for direct installation at locations with continuous operating temperatures ≤120℃, 150℃ transient peak (max 10 minute duration). They are NOT suitable for direct flush-mount installation on combustors, high-pressure turbine stages, or afterburner sections where continuous temperatures exceed 150℃, nor for >20kHz high-frequency combustion dynamics measurement. For these high-temperature/high-bandwidth applications, refer to our MPT800 series remote-mount fiber-optic pressure sensing solution.

Remote Mount Solution for Higher-Temperature Points

For static or low-frequency dynamic pressure measurement on points above 150℃ (e.g. compressor outlet static pressure, exhaust static pressure) where you don’t need 200kHz-level high-frequency response for combustion dynamics testing, you don’t need to buy expensive high-temperature sensors. We provide a fully validated remote-mount kit:

2mm inner diameter insulated, heat-sinked stainless steel pressure line connected directly to the hot-section pressure tap;
Our -55~150℃ pressure sensor mounted 1-1.5m away from the hot surface, where ambient temperatures stay consistently below 120℃;
Pre-calculated frequency response compensation for the pressure line, to ensure dynamic measurement error stays below 0.1%FS for signals below 5kHz.
This approach has been used in dozens of bench test programs: measurement accuracy is identical to direct-mount high-temperature sensors, but costs 80% less, and delivery is 8 weeks faster. For high-frequency combustion testing requiring flush mount on hot sections, we can connect you with our vetted high-temperature sensor partner network as part of your full test setup.

Field-Calibrated Companion Kit for Synchronized Testing

Over 70% of line measurement errors on aero-engine tests come from unaccounted vibration interference: pipe resonance near pumps and gearboxes can create false pressure signals that look like real pressure pulsations. Matching sensors from different vendors often leads to sync errors, incompatible power supplies, and days of on-site debugging.
We pre-calibrate all companion parts to work seamlessly with our pressure sensors, so you can plug them directly into your existing DAQ system:

Proven Reliability & Trust Validation

Quality Control & Calibration Process

Every single MPT series sensor completes 3 mandatory verification steps before shipment, zero exceptions for bulk or sample orders:

Room-Temperature Calibration

5-point up/down pressure cycle test to verify static accuracy, hysteresis and repeatability at 25℃ reference conditions.

Full-Temperature Compensation

-55~150℃ thermal cycle calibration to map and compensate zero/span drift across the full operating temperature range.

Vibration Qualification

100g RMS 20-2000Hz sine/random vibration sweep across all 3 axes, with post-vibration performance check to confirm no drift or damage.

Every unit ships with a hard-copy and digital calibration report linked to a unique laser-etched serial number, which can be verified 24/7 via our public serial lookup portal for full SI-traceable metrology traceability. All sensors meet GJB150A (Chinese military aerospace environmental standard, test levels equivalent to DO-160G) requirements for vibration, shock, temperature cycling and EMC.

Core Advantages of 150℃ Zone-Optimized Sensors

We do not upsell unnecessary high-temperature sensors for cold/medium section points. By optimizing specifically for the most common 150℃ operating zone across aero engines, we deliver measurable, practical benefits that generic wide-range sensors cannot match:

💰

Cost Advantage

45% Lower Cost

At equivalent accuracy levels, our 150℃ sensors are priced at 1/3 the cost of 400℃+ rated high-temperature aero sensors, drastically reducing test costs for pre-research programs, bench debugging and MRO operations, with no performance penalty for your actual operating conditions.

⚡

Lead Time Advantage

4-6 Weeks Delivery

All standard models are held in dedicated finished within 4-6 Weeks

📊

Stability Advantage

30% Lower Drift

A narrower calibrated temperature range allows more precise compensation algorithms. Full-temperature zero drift is 30% lower than wide-range high-temperature sensors that sacrifice low/medium temperature accuracy to cover 400℃+ ranges, delivering more consistent data during long-duration test runs.

Frequently Asked Questions

Q: Your sensors are only rated to 150℃ — can they really handle aero-engine test environments?
A: Yes. The 600℃+ high-temperature sensors you commonly see are only required for direct flush installation on hot gas path components, where sensors are exposed directly to combustion gas. The vast majority of line and accessory points on an engine operate below 120℃ continuously, and our 150℃ rating provides full headroom for transient temperature spikes during startup and shutdown. These sensors are built to the same vibration, shock and EMC standards as high-temperature aerospace sensors, but are optimized for the narrower temperature range to deliver better stability and lower cost.
Q: Why would I choose these over a high-temperature sensor that works everywhere?
A: High-temperature sensors require specialized high-temperature electronics and packaging, which makes them 3-4x more expensive, with much longer lead times. For points that never reach high temperatures, the extra temperature rating is unused overhead — you’re paying for capability you don’t need, and often getting worse temperature stability because the compensation is spread across a much wider temperature range. Our customers typically cut their line sensor costs by 60% using these sensors, with no loss of measurement accuracy.

Q: Do the matched accelerometers work with other brand pressure sensors?
A: Yes. The accelerometers use standard IEPE output, so they will work with any standard DAQ system. We pre-calibrate the timing alignment with our own pressure sensors for plug-and-play use, but they can be used as standalone vibration sensors for line measurement as well.
Q: Can you provide sensors for combustion dynamics testing?
A: Our current line of -55~150℃ sensors are not suitable for direct flush-mount combustion measurement, which requires specialized high-temperature, high-frequency sensors. We work with a vetted network of high-temperature sensor manufacturers for these applications, and can provide a full integrated package including our line sensors, third-party hot-section sensors, and mounting hardware if needed.
Q: What warranty and support do you provide?
A: All aero-engine sensors come with a 1-year warranty.
