Description

Overview
The 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.
Main features
  • Mercury filled construction for melt/high-temperature applications
  • Digital IO-Link output interface (smart device, Industry 4.0 ready)
  • Performance Level PLd and SIL2 approvals for Functional Safety
  • Capability to read media temperature up to 400°C (750°F)
  • Autozero function
  • Auxiliary/process information available over IO-Link protocol

Typical technical characteristics (excerpt)
  • Pressure ranges: 0-17 to 0-2000 bar / 0-250 to 0-30000 psi
  • Accuracy classes: < ±0.25% FS (H) ; < ±0.5% FS (M)
  • Standard threads: 1/2-20 UNF, M18x1.5
  • Diaphragm materials/coatings: 15-5 PH diaphragm with GTP+ coating; 17-7 PH corrugated diaphragm with GTP+ coating for ranges below 100 bar / 1500 psi
  • Rangeability: 3:1

Applications / Advantages
  • Designed for melt and other high-temperature processes where media temperature measurement up to 400°C is required
