TXR72900 - Eddy Current Vibration Probe - 90mV/mm/s IP67 Stainless Industrial Sensor

1. Ultra-Rugged Vibration Sensor Overview​

The ProvibTech TXR72900 is a high-fidelity industrial accelerometer engineered for mission-critical applications in the world's most demanding environments. Featuring a ​hermetically sealed titanium housing (Grade 5 Ti-6Al-4V)​​ with ​integral mineral-insulated cable, this sensor delivers ±1% accuracy across its ​​±100g measurement range​ with ​50mV/g sensitivity. Its laser-welded construction achieves ​IP68/IP69K protection​ against 150-bar washdowns, corrosive chemicals (pH 0.5-14), and deep submersion (3m/24hr). Operating from ​​-55°C to +150°C continuous (+300°C peak)​, it incorporates ​IEEE 1451.4 TEDS technology​ for plug-and-play calibration. Certified for ​ATEX/IECEx Zone 0/21​ and ​SIL 3 compliance, this sensor withstands 10,000g shocks while maintaining precision in aerospace test stands, nuclear reactors, and heavy mining operations where standard sensors fail catastrophically.

​2. Critical Performance Specifications​

This accelerometer delivers 0.5Hz–10kHz frequency response (±3dB) with <100μg/√Hz noise floor at 1Hz. Electrical specifications include IEPE constant current excitation (2-20mA), 50mV/g sensitivity (±3%), and <0.5% non-linearity. The 2m mineral-insulated cable features double-shielded construction with 120dB EMI rejection. Mechanical resilience includes 10,000g shock survivability (MIL-STD-810H), 1,000g RMS vibration resistance, and M5×0.8 threaded mounting. Environmental certifications cover ATEX/IECEx Zone 0 (Ex ia IIC T150°C Ga), NEMA 6P, and DNV-GL marine approval. Phase coherence is maintained within ±0.5° up to 5kHz for precise phase analysis.

​3. Extreme Industrial Applications​

This sensor excels in lethal-environment monitoring:

• ​Rocket Engine Test Stands: Combustion instability detection during full-thrust firings
• ​Nuclear Reactor Coolant Pumps: Primary loop vibration surveillance in PWR facilities
• ​Deep-Sea Mining ROVs: Hydraulic cutter head monitoring at 3,000m depth
• ​Geothermal Wellheads: Downhole tool vibration in 150°C H₂S environments
• ​Hypersonic Wind Tunnels: Shock wave impact measurement at Mach 7+
• ​Blast Furnace Casers: Roller monitoring near 1,400°C molten metal
• ​Arctic Oil Drilling: Percussive drill monitoring at -55°C
• ​High-Energy Physics: Particle accelerator component resonance testing
  Its Zone 0 certification (Ex ia) allows permanent installation in continuously explosive atmospheres like hydrogen refueling stations or coal mill baghouses where ignition sources are prohibited.

​4. Unmatched Performance Advantages​

• ​Thermal Supremacy:
  ±0.02%/°C sensitivity drift from -55°C to +150°C
  Quartz shear design minimizes pyroelectric effects
• ​Hazardous Area Dominance:
  Ex ia IIC T150°Ga certification for Zone 0/20
  <0.015W power dissipation prevents ignition
• ​Signal Integrity:
  Mineral-insulated cable provides 120dB EMI immunity
  Ground loop isolation via triple-shield construction
• ​Mechanical Survivability:
  10,000g shock rating (IEC 60068-2-27)
  35kHz resonance frequency for high-fidelity capture
• ​Corrosion Immunity:
  Titanium withstands pH 0.5-14 chemicals
  5,000hr salt spray resistance (ISO 9227)
• ​Maintenance Revolution:
  Hot-swappable connectors enable <3-min replacement
  TEDS stores calibration/installation history

​5. Advanced Sensing & Safety Architecture​

​Measurement Precision:

1. ​Shear-Mode Quartz Sensing:
   • Crystal elements generate charge proportional to acceleration
   • Low-noise JFET amplifier (<80μg/√Hz)
2. ​Thermal Compensation:
   • On-board RTD enables real-time sensitivity correction
   • ±0.05% accuracy across temperature range
3. ​Fail-Safe Operation:

   ​Condition​	​Output Response​	​TEDS Code​
   Normal	0.5-4.5V (±100g)	-
   Sensor Fault	Clamped at 0V ±0.1V	Error 1
   Cable Break	Current drop to <1.5mA	Error 2
   Overload (>105g)	Saturated at ±5.2V	Warning 3
   Temperature Fault	Output derated 50%	Error 4

​Explosion Protection:

• Triple-redundant Zener barriers limit Ui=5V, Ii=10mA
• Hermetic seals prevent gas permeation (helium leak rate <10⁻⁸ cc/sec)
• Surface temperature limited to 150°C in fault conditions
