Features

SS115 series flush pressure transducer is designed using piezoresistive technology. It features a stainless steel 316L open diaphragm. The transducer operates based on the principle of the piezoresistive effect. The 316L stainless steel housing protects the silicon chip. The isolated housing is filled with silicone oil. The transducer covers a pressure range of -1 bar to 1000 bar and operates at temperatures from -20 to 100°C. It is also available with various flush pressure ports to meet different requirements.

SS115 series has a ring on the diaphragm, a so-called semi-flush diaphragm. The flush diaphragm enables the accurate cleaning of the transducer and prevents the formation of residuals on the measuring area. Typically used in chemical and process engineering, the food industry, pulp and paper, and mining.
