It measures differential pressure (ΔP)—the difference between two pressure points—commonly used for flow, level, and filter monitoring.
Standard accuracy is ±0.075% of span, with options as tight as ±0.04% for high-performance applications.
It covers a wide range from ±0.1 inH₂O to ±2000 psi, depending on the selected sensor range.
It’s Emerson’s patented design that allows for compact, integrated mounting with manifolds and seals—ideal for space-saving and modular installations.
Yes. It’s certified for use in explosion-proof, intrinsically safe, and non-incendive environments (ATEX, IECEx, FM, CSA, etc.).
It offers 10-year stability of ±0.2% of URL, reducing recalibration needs and maintenance costs.
Standard is 316L stainless steel, with options like Alloy C-276, Tantalum, or Gold-plated materials for corrosive media.
It can be configured via a HART communicator, AMS Device Manager, or Field Communicator. Installation requires proper impulse line routing and electrical grounding per the manual.
