Description
Applications requiring a constantly monitored flow of cooling or cleaning
water now have the perfect solution with the launch of the new PF3W Digital
Flow Switch Series from the world leaders in pneumatics – SMC. Developed
following the success of SMC’s PF2W flow switch range, their R&D engineers
have now taken these flow switches to a new level by improving both their
design and operating performance. Depending on the selected model, the new
Series PF3W is now up to 40% smaller in volume than the previous range
thereby offering improved piping space and flexibility. Designed to work
with fluids up to 90ºC, these switches incorporate an in-built temperature
sensor so that both flow and fluid temperature can be effectively monitored
at the same time. According to SMC engineers, pressure losses have also
been reduced when compared to the previous range and the new PF3W can also
be used with ethylene glycol operating fluid making these switches ideal
for use in chiller type applications. Further improvements include the
addition of two screens incorporating three colour numerical displays which
can also be rotated in both clockwise and anti-clockwise directions thereby
offering even better display visibility during operation. Available as non
grease type and with analogue output if required, the new Series PF3W range
meets IP 65 enclosure protection standards and are both RoHS and CE
compliant.
