Differential pressure gauge DA09 is for the typical applications designed: chemical, petrochemical industry, process technology, marine and offshore technology, power plant technology, mechanical and plant engineering. The measuring system comprises a diaphragm and two separate pressure chambers. Differential pressure between the chambers causes axial movement of the diaphragms. A tie rod transfers this movement to an indicator. The seal between the pressure chamber and tie rod is realised with metal bellows. To compensate the static operating pressure, the measuring system is symmetrical. In the case of devices with additional electronic equipment, the connection is realised using a cable socket attached to the side. Pressure levels PN10 / PN25.
