• Vac.-1000 psi pressure range
• Stainless steel NEMA 4X enclosure
• Superior long-term stabilityand
repeatability
• Current/voltage/millivolt output
• Wide range of electricalconnections

• All-welded construction
Ashcroft®combines the proven polysili-
con thin film technology with its longtime
know-how of diaphragm seals to create
the KS sanitary pressure transmitter. The
all-welded stainless steel construction
meets the 3A Sanitary Standard 74-02.
The KS Sanitary Pressure Transmitter
features the benefits of polysilicon thin film
performance at an affordable price.
Modern chemical vapor disposition methods
provide simple, stable, molecular bonds
between a proven metal diaphragm and
polysilicon strain gage bridge. There are
no epoxies or bonding agents to contribute
to signal instability or drift. The integral
metal diaphragm and polysilicon bridge
are virtually unaffected by shock, vibration
or mounting position.
