This document describes two models of universal isolation diaphragm pressure sensors, the CYG102 and CYG103. The sensors feature a stainless steel isolation diaphragm and sensitive elements immersed in high purity silicon oil for good long-term stability under normal temperature and pressure conditions. The isolation diaphragm prevents measured media from leaking even if the sensor is damaged. The document provides technical specifications for each model including measurement range, zero output, overload rating, and full scale output. It also lists performance parameters for different sensor classifications and notes the standard pressure interface and shell materials.
