Digital Differential Pressure Indicator is known to analyze the difference between two pressures. Also, these are apt for the monitoring of filter contamination and enable accurate level measurement in closed vessels. Plus, it is suited for the overpressure measurement in clean rooms. It also allows for the control of pumping plants. It has two inlet ports that can be linked to the pressure points. This is preferred for its accurate as well as stable operation. Best thing about this sensing device is that it is unaffected by vibration.
