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

1. Ultra-High-Temperature Vibration Sensor Overview​

The ProvibTech TXA-33500 is a specialized piezoelectric accelerometer engineered for critical vibration monitoring in extreme thermal 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.

  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:
  ±0.03%/°C sensitivity drift (-55°C to +350°C)
  Low-thermal-shock quartz design minimizes pyroelectric noise
• ​Hazardous Area Dominance:
  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
  Vibration survival rating: 1,000g RMS (10Hz-10kHz)
• ​Corrosion Immunity:
  Titanium withstands H₂S/chlorides/pH 0.5-14
  5,000hr salt spray resistance (ISO 9227)
• ​Maintenance Efficiency:
  Hot-swappable connectors enable 3-minute replacement
  TEDS stores calibration/installation history

​5. Sensing Operation & Safety Architecture​

​High-Temperature Measurement Protocol:

1. ​Quartz Shear Sensing:
   • Crystal elements generate charge proportional to acceleration
   • Ultra-low-noise JFET amplifier (<150μg/√Hz)
2. ​Thermal Compensation:
   • Embedded RTD enables real-time sensitivity correction
   • Active cooling fins reduce thermal gradient errors
3. ​Fail-Safe Operation:
   • ​Output Voltage: 0.5-4.5V (±50g range)
   • ​Fault Responses:
     • 0V ±0.1V = Sensor fault (TEDS Error 1)
     • Current drop <1.5mA = Cable break
     • ±5.2V saturation = Overload (>55g)
   • ​TEDS Diagnostics:
     Stores calibration date, serial number, next service date

​Explosion Protection System:

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