Is there a differential intrinsically safe pressure sensor for measurement of pressure inside an offshore container relative to outside pressure? The application is to provide and monitor overpressure inside an offshore container. The normal pressure inside will be in the range of 75 Pa = 0.75 mbar, and a 4-20mA loop-powered is preferred, with at least ATEX intrinsic safety approval.
The DPT200 is a highly robust ATEX approved differential pressure transmitter which has a very low range capability which can be set to 0 to 100 Pa (1 mbar).
