Thin
Film Pressure Transducers Ashcroft Model K1

Thin
Film Pressure Transducers Ashcroft® Model K1 transmitter
introduces the benefits of polysilicon thin film performance
at affordable prices. Modern low-pressure chemical vapor
deposition methods provide simple, stable molecular
bonds between a proven metal diaphragm and a polysilicon
strain gage bridge. There are no epoxies or bonding
agents to contribute to signal instability or drift.
The polysilicon strain resistors combine very low noise
levels with very high signal output. There are no semiconductor
(p-n) junctions to change with temperature, time or
use. The integral metal diaphragm and polysilicon bridge
are virtually unaffected by shock, vibration or mounting
position.
Thin Film Pressure Transducers Ashcroft® Model K1 transmitters
are offered in many standard pressure ranges with either
current or voltage output signals. Transmitter performance
is directly traceable to the National Institute of Standards,
and Technology and specifications are conservatively
stated. A calibration test certificate is available
with each transmitter.
