GENERAL DESCRIPTION

The industrial pressure transmitter BPT200 contains a thin film sensor element and an electronic circuit. Calibration takes place electronically, so that the pressure 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 electronic block contains a programmable precision CMOS IC with EEPROM data storage and analogue signal path, which is suitable for extended operating temperature range. The special

steel membrane is completely vacuum-tight, extremely burstproof and can be used with all standard media in hydraulics, pneumatics, environmental technology, process technology and

automotive engineering, in as far as they are comparable 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 transmitters are offered. The transmitter performance are improved by continuous monitoring of the sensor temperature and corresponding corrections.
