Process viscometers certified for
combustible dust
Hydramotion's Intrinsically Safe XL7-15x series process viscometers are now available certified to ATEX Ex II 1GD for use in hazardous atmospheres.
Hydramotion announced an extension to the certification of its Intrinsically Safe XL7-15x series process viscometers The instruments are now available certified to ATEX Ex II 1GD for use in hazardous atmospheres where combustible dust as well as explosive gas may be present

Process viscometers get CSA approval
Hydramotion has announced that its XL7 process viscometers have now been granted CSA approval for Hazardous Area applications in Canada.
The extension certifies that the XL7 is fully compliant with IEC standards 61241-0:2004 (Dust General Requirements) and IEC 61241-11:2005 (protection by intrinsic safety "iD") and meets all the relevant Essential Health and Safety Requirements in Annex II of the ATEX Directive 94/9/EC.
The certification widens still further the range of applications for the XL7-15x series, which is already certified for use in Zone 0 Hazardous Areas (presence of explosive gas), equivalent to Class 1, Div 1, Group A in north America.
The use of intrinsically safe instruments has become ever more important with the introduction of the UK Dangerous Substances and Explosive Atmospheres Regulations (DSEAR).
Typical applications for the intrinsically safe XL7 range include the measurement of petroleum products, polymers, resins or solvent-based lacquers and varnishes.
With the extended certification, XL7 viscometers can also be used in applications such as the measurement of coal/oil slurries, where finely-divided coal dust presents a significant combustion hazard.
Another possibility is pharmaceutical production, which can involve a mixture of combustible dusts and solvents that are easily ignited by static discharge.
Ideal for these and many other applications, the XL7 is a field-hardened, rugged instrument that can be used in any fluid under any process conditions.
The standard sensor is an all-welded 316 stainless steel construction which may be mounted in any orientation in any tank or pipe, no matter what size.
The digital readout unit can be mounted up to 3000 metres from the transducer, and Hydramotion will supply a suitable IS barrier on request.
As the XL7 viscometer has no moving parts, seals or bearings that could wear out or fail in service, it needs virtually no maintenance and no on-site recalibration.
With very high sensitivity and excellent repeatability, the XL7 must be the instrument of choice for process viscometry, no matter how harsh or hazardous the measurement conditions may be. Request a free brochure from Hydramotion ...
