Categories Pressure, Differential Pressure & Flow Controller
DPT-Ctrl enables to control constant pressure or flow of fans, VAV systems or dampers. Its two lined display shows the direction of the control output and the measurement value at the same time. It is possible to select either current or voltage for both the control output and the differential pressure or flow output. The optional autozero function eliminates the need for periodic manual zero point calibration.
