The Cerabar PMP21 is a compact, durable pressure transmitter with a piezoresistive metal sensor for absolute and gauge pressure. With 0.3% accuracy, IO‑Link, and 316L stainless steel, it ensures reliable performance.
The Cerabar PMP21 is a versatile pressure transmitter for reliable measurement in gases and liquids. Its piezoresistive metallic diaphragm ensures precise readings across a wide span from 400mbar (5.8psi) to 400bar (5,800psi), suiting a broad range of industrial applications. Built from 316L stainless steel with ingress protection up to IP68, it withstands submerged or harsh outdoor use. Reference accuracy is 0.3% with long‑term stability of 0.2% URL/year for dependable continuous operation. Multiple process connections (G, NPT, DIN, JIS) and outputs, 4–20mA and IO‑Link, enable easy integration. Extensive hazardous and marine approvals (ATEX, FM, CSA, IECEx, NEPSI, UKEx, DNV/ABS/LR/RINA) support safety‑critical installations. For utilities, pump systems, machines, and process vessels, PMP21 delivers a durable, flexible, compact solution.
