Model KS Sanitary
Pressure Transmitter
The Ashcroft trade name has
been synonymous with pres-
sure for over 150 years. Since
1987, the Transducer Operation
of Dresser Instrument Division
has been manufacturing quality
industrial pressure transducers
serving a multitude of markets.
Whatever your application, we
have the technology to provide
either standard or customized
designs to fit your requirements.
Each pressure transducer is
100% tested and calibrated in
our ISO-9001 certified facility in
Milford, Connecticut. The com-
mitment of our engineering
staff, direct sales force and dis-
tribution network ensure that
the service and application
expertise you need to maintain
safety and performance in your
application is always available
when and where you need it.
The people of Dresser
Instrument Division are here to
provide the best quality prod-
ucts and service best suited to
our customer’s needs.
The KS sanitary pressure
transmitter combines a
pro ven thin film sensor tech-
nology and 3A standards f or
sanitary applications.
