KELLER Series D piezoresistive OEM pressure transmitters

The KELLER Series D piezoresistive OEM pressure transmitters are designed for applications in strongly hazardous areas of the gas group II (industry applications). They feature the combination of a robust industrial pressure transducer and the I²C microcontroller interface. The intrinsically safe D-line OEM transmitters have an embedded digital signal processing (DSP) core for the compensation and normalisation of the output values.

Performance features include pressure ranges of 1 to 1000 bar; accuracy (0.15%FS), long-term stability and no hysteresis; ultralow power consumption, optimised for battery-powered applications; hermetically protected sensor electronics, extremely resistant to environmental influences; ultracompact, robust housing made from stainless steel; no external electronics for compensation or signal processing; and easy integration into microcontroller-based systems. The internal two-chip solution with pressure sensor and signal processing separation provides a high degree of flexibility.
