I am looking for a pressure tranducer to measure fluid pressure thru a nozzle. It is used as part of a viscometer measurement. The orientation of the nozzle is such that the operating pressure is between -1 PSIG to +2 PSIG. We are currently using a 0 - 15PSIG (4-20ma) pressure transducer however I am looking for something that has a smaller range and will handle vacuum as well. We can not( rather not)redesign the Nozzle diameter because of flow requirements and pumping pressure constraints. I am looking for a range in the area of -5mmHg to 5PSIG.
Any suggestions would be appreciated.
