OverviewThe ILM series are mercury-filled pressure transmitters with IO-Link digital output and Performance Level 'd'/SIL2 (PLd/SIL2) options, specifically engineered for high-temperature melt applications. The sensors use a hydraulic transmission principle and are designed for Industry 4.0 environments, providing auxiliary information via IO-Link to help prevent machine downtime. The ILM series can read media temperatures up to 400°C (750°F) and is suitable for Functional Safety applications.
