The Model 550 measures low pressures from 10 in. W.C. up to 400 in. W.C. It is packaged in a 318 stainless steel housing for use in general purpose and  submersible applications such as water, waste water and viscous fluids. It features a 3:1 range turndown for field adjustment from 110% to 32% of the nominal pressure range, making it ideal for applications that are subject to overpressure. This unit is RFI/lightning protected and is also offered in an optional Galvanic Intrinsic safe design.
