เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น SME
คุณลักษณะ
The SME pressure transducer is a space saving light weight. Despite the compressed dimensions and miniaturized design the SME is robust and all stainless steel. At the same time it is full of Know-How and can be customized to individual requirements such as pressure range or output signal. The SME is not a product “off the rack”. Popular applications are motor sport and race cars. The well-known stainless steel design makes this product as robust and reliable as our standard products.
