Datasheet Preassure Transmitter P21   PERFORMANCE FEATURES Flush process connection Dry ceramic sensor Accuracy ≤ 0,5 % Smallest measuring range: 0…250 mbar Largest measuring range: 0…100 bar Negative pressure measuring range: up to -1 bar Analog output: 4…20 mA, 2-wires 0…10 V, 3-wires 0…5 V, 3-wires 0,5…4,5 V, 3-wires ratiometric The P21 model is designed for use in applications where media tend to deposit and clog the sensor. Various output signals, process connections and high pressure ranges widen its area of application. A compact frontflush process connection prevents hidden edges and drill holes, in combination with a resistant ceramic sensor, optimal cleaning and maintenance can be ensured. The piezoresistive measuring principle allows for economical application in most liquid and gaseous media. Its compact housing is made of high-quality stainless steel 1.4404 and is therefore suitable for almost all media. Our modular design concept provides a wide variety of products.
