Vibration Monitoring for the Petroleum and Chemical Industry

Download the printer-friendly Vibration Monitoring for the Petroleum and Chemical Industry Application Note

Many petroleum/chemical applications have hazardous environments due to gas, oil, or dust that could create a combustible atmosphere in and around the machines. As a result, vibration monitoring of critical assets provides key performance indicators for petrochemical plants worldwide to maintain employee safety and prevent operational downtime.

CTC’s extensive experience in petrochemical environments has driven the design and manufacture of rugged and reliable vibration monitoring products that stand up to these environmental challenges and include CTC’s best-in-class warranties.

CTC and PRO Lines feature products that are certified through CSA, ATEX, and IECEx for Intrinsically Safe (Class 1, Division 1, or Zone 0) and Non-Arcing, Non-Sparking (Class 1, Division 2, or Zone 2) environments.

Common Applications Include:

Conveyors
Fans
Gear Boxes
Motors
Pumps
Compressors

Industrial Fan

Hazardous-Area Approved Proximity Probe Set Offerings:

8 mm intrinsically safe proximity probe driver with coiled extension cable and probe tip
shown above: 8 mm Hazardous-Area Approved Proximity Probe Set

CTC offers a complete line of hazardous-area approved proximity probe systems designed, built, and tested to endure prolonged use in the harshest industrial environments. PRO Line proximity probe systems are available in FFv^TM 5 mm, 8 mm, 11 mm, and 25 mm systems. The variety of probe sizes offered allows for accurate and precise machinery measurements for applications involving radial dynamic, axial rotor position, 4-20 mA, and thermal case expansion measurements. Complete PRO proximity probe systems are compatible with all standard condition monitoring software, including Bently Nevada® software.

For intrinsically-safe applications, any standard CTC cabling and connector options may be used in conjunction with a barrier. Hazardous-rated sensors using the intrinsic safety protection method must be used with barriers to limit the energy a sensor can receive. Cabling brings the signal from the sensor to the Zener diode barrier or galvanic isolator, which is the energy-limiting interface. The signal is transferred through the barrier (which can be located in the hazardous or non-hazardous area), to measurement equipment in the hazardous areas, such as a data collector or junction box.
