Engine development pushes components to the limit—especially when measuring exhaust pressures in extreme heat. That’s why Kistler just leveled up its flagship 4017A miniature absolute pressure sensor with a game-changing addition: a water-cooled adapter that keeps precision intact, even when temperatures soar.
🎯 The Challenge: Accuracy in the Heat Zone
Piezoresistive absolute pressure sensors are the gold standard for capturing static and dynamic pressures in powertrain R&D. But here’s the catch: high accuracy demands stable temperatures. In exhaust manifolds or turbocharger testing, ambient heat can easily push sensors beyond their operating limits—compromising data and risking hardware.
Kistler’s solution? Don’t just shield the sensor—actively cool it.
❄️ Meet the 4017A…W Set: Precision Meets Thermal Intelligence
The new 4017A…W package combines two innovations in one compact system:
🔹 4017A sensor: The world’s smallest media-separated absolute pressure sensor (piezoresistive, oil-filled measuring cell)
🔹 7547A adapter: Integrated water cooling + welded heat shield for maximum thermal protection
✅ 25% smaller than Kistler’s previous water-cooled 4049B series—ideal for tight engine bays
✅ M8x0.75 thread connection for versatile, space-efficient installation
✅ Optimized cooling channels + low-mass design = faster heat dissipation, longer sensor life
✅ Vibration-resistant: Lightweight build reduces stress from engine oscillations
✅ Modular & service-friendly: Swap sensor or adapter independently; disconnect for easy cleaning
📊 Performance That Doesn’t Compromise
Don’t let the size fool you—this mini sensor delivers lab-grade results:
✨ Measurement accuracy: ≤1% FSO (Full Scale Output)
✨ Digital temperature compensation: Model-based correction in real time, zero delay
✨ PiezoSmart® technology: Auto-recognition by Kistler amplifiers—no manual config, zero setup errors
✨ Media compatibility: Oil-filled, separated cell handles aggressive gaseous media safely
✨ Pressure ranges: Available up to 50 bar to match diverse test scenarios
🔗 Seamless Integration, End-to-End
The 4017A…W plugs directly into Kistler’s ecosystem of piezoresistive amplifiers: • 4665B (2-channel, SCP/KiBox1)
• 4667A (1-channel PRAQ, KiBox2)
• 4624A (standalone 1-channel)
Plus, digital temperature monitoring gives engineers real-time visibility into sensor health—critical for long-duration test cycles.
💡 Why This Matters for R&D Teams
| Before | After with 4017A…W |
|---|---|
| Bulky sensors limit placement options | Ultra-compact design fits constrained spaces |
| Thermal drift risks data integrity | Active cooling + digital compensation = rock-solid accuracy |
| Complex setup invites human error | PiezoSmart auto-configures in seconds |
| Downtime for maintenance | Modular design = quick swaps, easy cleaning |
In short: More reliable data. Faster iterations. Lower total cost of ownership.
