BD SENSORS GmbH
About
BD SENSORS GmbH is a medium-sized, family-owned German manufacturer headquartered in Thierstein, Bavaria, with over 300 employees across operations in Germany, the Czech Republic, the United States, and China. Founded in 1994, the company concentrates exclusively on electronic pressure measurement and hydrostatic level measurement technology, producing five distinct sensor technologies in-house: capacitive ceramic (99.9% Al₂O₃), silicon with media separation, ceramic thick-film in flush and monolithic designs, thin-film on steel, and piezoresistive. The product portfolio spans pressure transmitters in both analog and digital configurations covering measurement ranges from 0.1 mbar to 10,000 bar, including the DMK 387 versatile pressure transmitter for small system pressures and filling heights. Digital transmitters support IO-Link, RS 485 Modbus, and I²C output protocols. Submersible level probes feature the LMK 808 with its ceramic sensor, detachable sensor head for easy maintenance, and integrated overvoltage protection resistant to rodent damage. Differential pressure transmitters serve flow, level, and filter monitoring applications. The BD|SIMEX evaluation product line provides process displays, data loggers (including the CIT 750), impulse counters, and I/O modules for integrating measurement devices into control systems. Capacitive ceramic sensors are specifically suited for aggressive media in drinking water, wastewater, and chemical applications, while thin-film sensors handle technical gases including oxygen and hydrogen. The company operates a DAkkS-accredited in-house calibration laboratory covering relative and absolute pressures up to 800 bar, and offers custom product modifications and repair services across its entire range.
