The BPT50 low cost pressure transmitter contains a thin-film sensor element and an electronic circuit. Calibration takes place electronically and thus the transmitter displays a comparably small total error and is stable in the long term. The hermetically welded measuring cell ensures a high degree of long-term resistance to leakage and stability. The special steel membrane is completely vacuum-tight, extremely burstproof, and can be used with all standard media in pneumatics, environmental technology, process technology, and automotive engineering as far as such are compatible with special steel. This thereby covers use in standard applications in mobile hydraulics and in other areas of application. The great exactness and the robust, compact structure guarantee a broad range of possible uses in industry as well as for hightemperature applications. On the basis of the combinability of different mechanical and electronic connections, a variety of different pressure transmitter versions is offered.
