Absolute pressure sensor 4017A

piezoresistivevoltage outputcurrent output

The pressure sensor 4017A is a unique pressure transducer combining compact dimensions with highest accuracy over a wide temperature range. The measuring principle is based on a Wheatstone measuring bridge, which generates an electrical signal proportional to the applied pressure. The bridge consists of piezoresistive resistors embedded in an oil-filled measuring cell. The innovative design ensures long-term stability and high durability in various applications. A specially designed stainless-steel diaphragm provides high sensitivity over the entire pressure range and guarantees excellent media compatibility. The piezoresistive measuring principle has the unique ability to measure not only static pressures, but also makes the sensor suitable for measuring dynamic pressures with high frequency ranges. The sensor is equipped with fully shielded cabling and anti-kink sleeving to provide best protection against damage. Integrated PiezoSmart system for automatic sensor identification ensures high process reliability during the measurements. The parametrization of the measuring chain occurs automatically, and the sensor is ready for measurements after connection to the amplifier (plug and play). Digital temperature compensation uses a specific model-based compensation method to achieve highest accuracy. With the help of an individual sensor-based polynomial model, the output pressure signal is corrected according to the sensor temperature without delay.
