Description
WIKA S-10 and S-11 pressure transmitters are precision engineered to fit most industrial pressure measurement applications. The compact, rugged design makes these instruments suitable for applications including hydraulics and pneumatics,vacuum,testequipment,liquidlevelmeasurement,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 flush diaphragm process connection Right: S-11 with flush diaphragm process connection and
integral cooling element
The S-11 transmitter features a flush diaphragm process connection.The S-11 is specifically designed for the measurement of viscous fluids 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 300OF.
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.

1)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 specifications but may lead to zero and span shifts
**Exceeding the burst pressure may result in destruction of the transmitter and possible loss of media
