Nitrogen is to be introduced into the tank for protection, maintaining a slight positive pressure inside the tank (around 20~30 mmH2O) to prevent outside air from entering. The pressure signal must be transmitted to the DCS for display. I work in the field of manufacturing processes and don’t understand instruments; please help me choose a model.
The EJA120 differential pressure gauge should meet your requirements. Range: 10-100mmH2O.
The Rosemount 3051CG2 can meet your requirements; simply inform the manufacturer of your parameter range when making the purchase.
A piezometric transducer capable of measuring micro-pressure; if necessary, a diaphragm gauge and transmitter can be installed on-site for comparison
