Vibration Sensors Serve as Predictive Maintenance Tool

July 24, 2009

Wilcoxon Research recently announced the release of six new Class I Division 2 (Zone 2) accelerometers.  In addition to the vibration sensors, the company is also releasing three compatible cable-connector assemblies suitable for installation in a Class I Division 2 (Zone 2) environment.

"Industries such as oil and gas and chemical processing are increasingly recognizing the value of vibration monitoring as a predictive maintenance tool and as a cost savings measure," said Tom Smith, Vice President of Sales and Marketing.  "To best serve these customers, we certified several of our most popular vibration sensors as Class I Division 2."  Other industries that commonly have Class I Division 2 (Zone 2) hazardous areas are mining, steel, petrochemical processing, and pharmaceuticals.

The six sensors which received the Class I Division 2 (Zone 2) certification all have a sensitivity of 100 mV/g, and a tight +5% sensitivity tolerance, commonly called general purpose industrial accelerometers.  The standard top exit model is the 786A-D2.  The standard side exit model is the 787A-D2, which is also available with a metric M8 mounting stud, model 787A-M8-D2.  The 780A-D2 is a compact sensor ideal for portable data collection.  The integral cable model is the 786F-D2.  The 786T-D2 is a dual output model that senses both vibration and temperature.
