Motion Sensors
(MSI) intrinsically safe Digi-pulse sensors feature the
same high quality construction and materials as our
standard Digi-Pulse
models. They are certified by CSA (with NRTL/C) and LCIE
to ATEX (94/9/EC) for Class I, Zone 0, IIC and II 1 G
EEx ia IIC T4, or Class I, Zone 0, IIA and II 1 G EEx ia
IIA T4 hazardous locations.
In addition to the models specified, MSI can make
custom intrinsically safe Digi-Pulse sensors in other
lengths, diameters, configurations, mounting threads
(e.g., metric) as well as with different operating
specifications and options like pigtail leads, NPT
threads for explosion proof applications, etc. to
satisfy special requirements. Our certifications permit
us to make intrinsically safe versions of almost any MSI
sensor, or to customize a sensor to suit a particular
application or customer need. The customization process
for Intrinsically Safe products at MSI is
straightforward, quick, offers more choice, and is less
costly than our competitors. Just tell us what you want
and we will provide a fully certified CUSTOM
INTRINSICALLY SAFE PRODUCT IN WEEKS, NOT MONTHS, made to
your specifications, even if you only need one piece!
This ability to provide rapid development of custom
certified product WITHOUT THE NORMAL CERTIFICATION COSTS
AND LEADTIMES is due to our unique "modular"
certification scheme with CSA and ATEX. If you do not
see a sensor that meets your needs please contact us to
learn how Motion Sensors can provide a customized
Intrinsically Safe Digi-Pulse sensor for your
application.
