28/09/2016 TE-SM/Haiying GuoSDE3 Customer Presentation Operating principle pressure sensor SDE3 1x relative pressure 5 The piezoresistive pressure sensing element is comprised of a silicon chip with diffused resistors. When mechanical stressing occurs (pressurisation of the silicon chip), the value of radially arranged resistors is increased, or the value of transversally arranged resistors is decreased. Measuring bridge imbalance determines the measured value. Atmosphere hole Measuring pressure port p1 Piezoresistive sensing element

Special in this case is a measurement pressure port (P2) on the active surface of the sensor element. Output is related to p1-p2. 1 piezoresistive sensing element Measuring pressure port p1 and p2 Indication is p1-p2

28/09/2016 TE-SM/Haiying GuoSDE3 Customer Presentation SDE3 pressure sensor 11 Customer benefits Optimising and monitoring pressure values at machines in process. Thereby no interruptions of production and fast cycles. Space and cost saving due to 2 independent pressure inputs as option (USP) Safe due to „lock function“ Fast installation due to integrated DIN rail and front panel mounting

28/09/2016 TE-SM/Haiying GuoSDE3 Customer Presentation SDE3 – Applications Fields of application: General automation market and also small parts handling with limited space conditions. The SDE3 can be used where information with regard to currently applied pressure are required and where space-saving assembly and convenient operation are of the essence. Main applications: System monitoring (pressure available?) Controller monitoring (pressure in desired range?) Vacuum (parts retained?) Leakage tests (pressure drop over time period?) Object detection (back-pressure present?) Differential pressure recording (valve switched or not switched) 12
