Datasheet Pressure Transmitter P121PERFORMANCE FEATURESDry capacitive ceramic sensor ■ Smallest measuring range: 0.. .40 mbar ■ Largest measuring range: 0.250 bar ■ Negative pressure measuring range: up to -1 bar ■ High overload capability ■ Compact and rugged design ■ Optionally in plastic PP or PVDF The P121 model was designed for use in harsh industrial environments. It features a high-resolution ceramic sensor, ATEX certification, and numerous configuration options. DNV certified, the sensor also finds use in marine applications and provides excellent mechanical resistance. The ceramic sensor element is resistant to aggressive and abrasive media. The capacitive measuring principle enables a very accurate and long-term stable measurement, even at lowest pressures and high overload resistance. Its compact housing is made of high-quality stainless steel 1.4404 and is therefore suitable for almost all media. For highly aggressive chemicals, variants in PP or PVDF are recommended. Our modular design concept provides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
