The absolute pressure transmitter of the series ADF/A is used in all areas of the pressure measurement. Typical uses are in the machines building and plant construction, the automation technology as well as in the cold technology and air conditioning technology. This pressure transmitter is a guarantor for high accuracy, long-run stability and reproducibility in the industrial pressure measurement and test engineering already for decades. Depending on the measuring range, the suitable sensor - piezoresistive or metal thin film is used. As output signal are 4-20 mA (2-wire) or 0-10 V (3-wire) available. The EMV-characteristics are tested according to EN 61326 and ensure a secure signal detection even by raise environment conditions.
