Product Announcement from Meggitt Sensing Systems - Wilcoxon Research


Accelerometers Certified Intrinsically Safe -Image

Meggitt Sensing Systems, the manufacturers of industry-leading Wilcoxon Research accelerometers and vibration sensor networks, announces 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 six general purpose accelerometers are suited to industrial machinery health monitoring of rotating equipment such as motors, pumps, fans, compressors, vibrating conveyors, chillers, gearboxes, reciprocating compressors, blowers, cooling towers, mixers, turbines and centrifuges. These types of machinery are typically found in hazardous area locations common to industries such as petrochemical, oil and gas, chemical processing, pharmaceuticals, food and beverage, pulp and paper, wastewater treatment, nuclear power, and power generation.

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.

The IECEx standards are recognized worldwide by most industrialized countries, including Australia, Brazil, Canada, China, Croatia, Czech Republic, Denmark, Finland, France, Germany, Hungary, India, Italy, Japan, Korea, Malaysia, The Netherlands, New Zealand, Norway, Poland, Republic of Serbia, Romania, Russia, Singapore, Slovenia, South Africa, Sweden, Switzerland, Turkey, United Kingdom, and the United States.

The International Electrotechnical Commission (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 and have been certified by SIRA to meet the quality system requirements of the IECEx scheme.

Meggitt's Wilcoxon Research line of vibration monitoring products includes other accelerometers and 4-20 mA sensors certified to be Intrinsically Safe, Explosion Proof, and approved for use in Class I Division 2 (Zone 2) environments.
