SERIES 40W
Pressure Sensor
Ǡ No wetted metal parts
Ǡ No gaskets required
Ǡ Non-clogging, protects instrumentation
Ǡ Bolt through design - positive
alignment, secure connection

The Series 40W pressure sensor isolates and protects instrumentation. The full-port design eliminates clogging, ensuring
accurate pressure measurement under the most difficult conditions. The elastomer sleeve senses pressure 360 degrees
around the inner circumference of the unit, overcoming problems like plugging and fouling of traditional diaphragm seals.
Combinations of elastomers and sensing fluids provide an
operating range of –20º F to +400º F. Standard units are rated
at 300 psi operating pressure and 450 psi surge pressure. All
areas exposed to the process media are elastomer covered.
Depending on the type of media being handled, elastomers
can be specified to offer the best combination of chemical
and abrasion resistance characteristics. The elastomer sleeve
extends to the full face of the flange, eliminating the need for
additional gaskets.

Sensor fits in bolt pattern
of mating flanges
