The intrinsically safe version of the HAVi vibration monitor is for use in hazardous and potentially explosive atmospheres. The intrinsically safe version is easily recognized by the yellow case.
The I.S. version works in exactly the same was as the standard HAVi and makes the same measurements and calculations. For more information please see the Standard HAVi page.
The intrinsically safe vibration monitor is intended for:
Equipment or Protective System Intended for use in Potentially Explosive Atmospheres Directive 94/9/EC
|ia||Intrinsic safety zone 1|
|IIC||Non mining test gas hydrogen|
|T4||Max surface temperature 135°C|
|Gb||Equipment protection zone 1|
|II 2G||Non mining, high protection, gas|
The intrinsically safe HAVi has been independently tested by Baseefa:
