STG08 Sanitary Flush Diaphragm Pressure Sensor

The STG08 pressure sensor uses a silicon piezoresistive sensing element with a stainless steel isolation diaphragm as the core measuring component. Each unit undergoes automated computer testing and laser trimming to achieve precise zero and temperature compensation over a wide operating temperature range. The signal conditioning circuit is integrated inside a stainless steel housing, converting the sensor signal into a standard industrial output.The sanitary diaphragm seal pressure transmitter is specifically designed for pressure and level measurement in hygienic environments such as the food processing, dairy, chemical, and pharmaceutical industries. The process connection adopts a hygienic tri-clamp diaphragm seal, ensuring easy cleaning and compliance with sanitary requirements.
