Datasheet S-10, S-11
Description
WIKA S-10 and S-11 pressure transmitters are precision
engineered to t most industrial pressure measurement
applications. The compact, rugged design makes these
instruments suitable for applications including hydraulics and
pneumatics, vacuum, test equipment, liquid level measurement, press
control, compressor control, pump protection and
numerous other processing and control operations. A wide range
of electrical connection and process connection options are available to meet almost any requirement.
Rugged construction
The S-10 features an all-welded stainless steel measuring cell for
improved media compatibility. There are no internal soft sealing
materials that may react with the media or deteriorate over time.
The compact case is also made of stainless steel and is available
with environmental protection ratings up to NEMA 6P / IP 68.

Center: S-11 with ush diaphragm process connection
Right: S-11 with ush diaphragm process connection and
integral cooling element
The S-11 transmitter features a ush diaphragm process
connection. The S-11 is specically designed for the
measurement of viscous uids or media containing solids
that may clog a NPT process connection. Flush diaphragm
pressure transmitters are available in pressure ranges
from 50 InWC to 8,000 psi. For high temperature media, an
integral cooling element is available on the S-11. This option
increases the maximum media temperature to 300
Each instrument undergoes extensive quality control testing
and calibration to achieve an accuracy of < 0.25% full scale.
The printed circuit boards use state-of-the-art surface mount
technology and are potted in silicone gel for protection
against mechanical shock, vibration and moisture. Each is
individually temperature compensated to assure accuracy
and long-term stability even when exposed to severe
ambient temperature variations.

Ranges only available with Model S-10
2)
For Model S-11 the burst pressure is limited to 21,000psi unless the pressure seal is accomplished by using the sealing ring underneath the hex.
*Pressure applied up to the maximum rating will cause no permanent change in specications but may lead to zero and span shifts
**Exceeding the burst pressure may result in destruction of the transmitter and possible loss of media
