Flush Diaphragm Pressure Transmitter Features
SS114 series flush diaphragm pressure transducer with cooling extensions integrated is designed for high-temperature applications; with three pcs of cooling fins, the working temperature can be up to 150°C, six pcs is up to 200°C and the maximum eight pcs can go up to 240°C.
SS114 series is designed by piezoresistive sensor technology for where a flush face is required for easier cleaning. 316L stainless steel housing protects the silicon chip, and silicone oil fills the isolated housing. The transducers can test various media. Typically for use in food, process, and industrial applications where the media is either viscous or is otherwise liable to block the port of a conventional pressure transducer with a recessed diaphragm or pressure port.
