Model SPR-2 & TPR-2 OEM Pressure Transducer

Brand: WIKA Alexander Wiegand SE & Co. KG

Design The heart of the measuring cell is a silicon chip, which is pressurised via a pressure transmission medium. As pressure transmission medium, a suitable filling liquid for the respective application is used. 

A diaphragm and a case from stainless steel make the transducer highly resistant to a wide variety of media. 

Individual Solutions The pressure transducers are manufactured on a flexible production line and can be individually adapted to suit customer requirements. 

Special Features The pressure transducer can be delivered either with or without linear temperature compensation. Alternatively, a test certificate for the sensor cell can be supplied with it, for active temperature compensation by the customers themselves. 

The assembly and connection concept guarantees a very high overload and burst pressure safety. The silicon chip provides a high measuring sensitivity, which enables measurement of even the lowest pressures.
