TXA-33500 - Eddy Current Vibration Probe - 50mV/mm/s IP67 Stainless Industrial Sensor

1. Extreme-Temperature Vibration Monitoring Solution​

The ProvibTech TXA-33500 is an industrial-grade piezoelectric accelerometer engineered for critical vibration monitoring in ultra-high-temperature environments. Featuring a ​hermetically sealed titanium housing (Grade 5 Ti-6Al-4V)​​ with ​integral mineral-insulated cable, this sensor operates continuously at ​​+350°C (33500 suffix)​​ with peak tolerance to ​​+450°C. Utilizing ​shear-mode quartz technology, it delivers ​​±5% accuracy​ across a ​​±50g range​ with ​10mV/g sensitivity. The laser-welded construction achieves ​IP68/IP69K protection​ against high-pressure steam (150 bar), corrosive chemicals (pH 0.5-14), and deep submersion (3m/24hr). Certified for ​ATEX/IECEx Zone 0/21​ and ​SIL 3 compliance, it incorporates ​IEEE 1451.4 TEDS memory​ for plug-and-play calibration. Designed for gas turbine exhausts, rocket test stands, and nuclear reactors, this sensor survives 10,000g shocks while maintaining precision where conventional sensors fail.

​2. Critical Performance Specifications​

This accelerometer delivers 2Hz–5kHz frequency response (±3dB) with 10mV/g sensitivity (±5%). Key parameters include ±50g measurement range (±1% FS linearity), <150μg/√Hz noise floor at 1Hz, and phase shift <1° @ 1kHz. Electrical specifications feature IEPE constant current excitation (2-20mA @ 18-30V DC) and 1.5m double-shielded mineral-insulated cable. Mechanical resilience includes 10,000g shock survival (IEC 60068-2-27), 1,000g RMS vibration resistance, and M5×0.8 threaded mounting. Environmental certifications cover ATEX Ex ia IIC T350°C Ga, IECEx equivalent, and IP68/IP69K protection. Thermal stability maintains ±0.03%/°C sensitivity drift from -55°C to +350°C.

​3. Ultra-High-Temperature Industrial Applications​

This sensor excels in extreme thermal environments:

• ​Jet Engine Testing: Exhaust section monitoring during 400°C+ full-thrust operations
• ​Nuclear Power Plants: Primary coolant pump vibration in 300°C PWR environments
• ​Petrochemical Cracking Furnaces: Tube vibration detection in ethylene plants
• ​Glass Manufacturing Lehrs: Roller bearing monitoring near 600°C molten glass
• ​Cement Rotary Kilns: Burning zone equipment surveillance
• ​Steel Continuous Casters: Mold oscillation at 1400°C proximity
• ​Hypersonic Wind Tunnels: Surface vibration at Mach 7+ speeds
• ​Geothermal Wellheads: Downhole tool monitoring in 350°C steam
  Its Zone 0 certification (Ex ia) allows permanent installation in continuously explosive atmospheres like hydrogen cooling systems or coal pulverizers where ignition sources are prohibited.

​4. Unmatched Functional Advantages​

• ​Thermal Resilience:
  Operates continuously at 350°C (450°C peak)
  Active thermal compensation via embedded RTD
• ​Hazardous Area Safety:
  Ex ia IIC T350°Ga certification for Zone 0/20
  <0.02W power dissipation prevents ignition
• ​Signal Integrity:
  Mineral-insulated cable provides 100dB EMI rejection
  Ground loop isolation through triple-layer shielding
• ​Mechanical Robustness:
  35kHz resonance frequency for high-fidelity capture
  Titanium housing withstands pH 0.5-14 chemicals
• ​Calibration Efficiency:
  TEDS auto-configuration reduces setup time
  NIST-traceable calibration included
• ​Maintenance Optimization:
  Hot-swappable connectors enable 3-minute replacement
  5,000hr salt spray resistance (ISO 9227)

​5. Advanced Sensing & Safety Architecture​

​Measurement Technology:

1. ​Shear-Mode Quartz Sensing:
   • Crystal elements generate charge proportional to acceleration
   • Low-noise JFET amplifier (<150μg/√Hz)
2. ​Thermal Management:
   • Real-time sensitivity correction via on-board RTD
   • Thermal barrier design minimizes gradient errors
3. ​Fault-Proof Operation:
   • Output clamps at 0V during sensor failure
   • Current drop <1.5mA indicates cable break
   • TEDS Error Codes flag specific faults

​Explosion Protection System:

• Triple-redundant Zener barriers limit energy (Ui=5V, Ii=10mA)
• Hermetic seals prevent gas permeation (<10⁻⁹ cc/sec helium leak rate)
• Surface temperature limited to 350°C in worst-case faults
