Differential pressure and volume flow transducer for monitoring differential pressure and volume flow of air and other non-flammable and non-aggressive gases. Three types with eight different measuring ranges are available for different applications. In addition to differential pressure all variants provide the calculated volume flow as second analog output signal. LCD models with RGB background light have a transparent cover. Display configuration, values for flow calculation (default 1.00) and threshold values for color changes can be parameterized via Thermokon USEapp. For a more precise measurement and for a better long-term stability we recommed the option "AZ" (automatic zero-point calibration). With the option board relay two-point controllers or a 2-stage 2-point controller for differential pressure or volume flow can be realized. The mounting base (included in delivery) allows mounting on a level surface or mounting on DIN rail TS35 (35x7,5 mm) according to EN 60715. Replaces DPA in the newly developed enclosure USE-L.
