HART-Enabled Vibration Transmitter 4-20mA with 5M Cable

The ProvibTech TM0180-A08-B00-C05-D05 is an advanced vibration transmitter engineered for predictive maintenance in industrial automation. Featuring 4-20mA + HART protocol output (A08 designation) and an integrated piezoelectric accelerometer (B00 suffix), this device delivers velocity RMS measurements (0-20mm/s) with ±3% accuracy. Its 316L stainless steel housing provides IP68/IP69K protection against dust, high-pressure washdowns, and temporary submersion. The "C05" denotes 5kHz frequency range with 0.5Hz high-pass filtering, while "D05" specifies a 5-meter PUR cable. Operating across -40°C to +125°C with ATEX/IECEx Zone 22 certification, it enables real-time vibration monitoring and diagnostics for critical rotating equipment in power generation, oil & gas, and heavy manufacturing facilities.

Signal Processing Workflow:

1. Piezoelectric Sensing:
   Quartz crystal generates charge proportional to acceleration
2. Conditioning Circuit:
   IEPE constant current excitation (4mA bias)
   0.5Hz high-pass filter removes low-frequency drift
3. Digital Conversion:
   24-bit ADC samples at 10kHz
   DSP calculates true RMS velocity (ISO 10816-1)
4. Output Generation:
   Analog: 4-20mA proportional to 0-20mm/s RMS
   Digital: HART protocol transmits:
   • Velocity RMS/Peak
   • Crest Factor
   • Temperature
   • FFT spectrum (400 lines)
