Intrinsically Safe Accelerometers Receive IECEx Certification


Nov 04, 2009

Wilcoxon Research, a supplier of vibration sensors and sensor networks, recently announced an additional Intrinsically Safe certification in accordance with IECEx requirements for six general purpose accelerometers.  The six accelerometers were approved for use in Class I Zone 0 hazardous areas.

The IECEx standards, which are recognized worldwide by most industrialized countries, are set forth by The International Electrotechnical Commission (IEC). The IEC publishes the IECEx scheme, a set of standards that specifies requirements for both hazardous area electrical equipment and requirements for the quality system of manufacturers of hazardous area electrical equipment. Certification organizations perform the testing and qualifications required by the IECEx scheme.  Wilcoxon Research sensors were tested to the IEC requirements by KEMA, a company specializing in strategic and technical energy consultancy,  and have been certified by Sira, a certification provider in the conformity assessment solutions field, to meet the quality system requirements of the IECEx scheme.

According to Tom Smith, vice president of sales and marketing, “These vibration sensors were previously approved as Intrinsically Safe by certifying agencies recognized in the U.S., Canada, and Europe.  Condition monitoring is growing in popularity across the world and the IECEx certification will help us better serve customers in other regions.”

Six general purpose accelerometers, with a sensitivity of 100 mV/g and a tight +5% sensitivity tolerance, were certified as Intrinsically Safe in accordance with the requirements of the IECEx standards.  The standard top exit model is the 786A-IS.  The standard side exit model is the 787A-IS, which is also available with a metric M8 mounting stud, model 787A-M8-IS.  The 780A-IS is a compact sensor.  The integral cable model is the 786F-IS.  The 786T-IS is a dual output model that senses both vibration and temperature.
