Intrinsic safety has
become an increasingly popular approach
for handling sensing requirements in
hazardous locations. These sensors are
intrinsically safe versions of Motion
Sensors (MSI)
Premium
or
Value
variable reluctance (VR) sensors. CSA
(with NRTL/C) and LCIE to ATEX (94/9/EC)
certify them. Intrinsically safe models
feature high quality construction and
materials.
In
addition to the models specified, MSI can make
custom Intrinsically Safe VR 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. Please contact
us to learn how Motion Sensors can provide a customized
Intrinsically Safe VR sensor for your
application.
