Strain gauge pressure transmitter ME SIL2

4-20 mA8 pin M12 connector1/2" UNF

Overview
The ME SIL2 is a pressure transmitter designed for high-temperature melt and process applications. It uses a fluid-filled (mercury option) hydraulic transmission to transfer pressure to a thick-film strain-gauge sensing element, enabling reliable measurement at media temperatures up to 400°C. A SIL2-certified variant is available for Functional Safety applications in process plants.

Main features

• Pressure ranges: from 0-17 to 0-2000 bar (0-250 to 0-30000 psi equivalents)
• Accuracy classes: < ±0.25% FS (H); < ±0.5% FS (M)
• Fluid-filled system (mercury option) for enhanced temperature stability
• SIL2 certification for Functional Safety applications
• Standard output: 4…20 mA (E option)
• Standard process connections: 1/2-20 UNF and M18x1.5 (other threads on request)
• Autozero: on-board or external option; Drift autocompensation available (SP version)
• Standard diaphragm: 15-5 PH stainless steel with GTP+ coating; 17-7 PH corrugated diaphragm with GTP+ coating available for lower ranges (<100 bar / 1500 psi)
• Mechanical/configurable options: rigid or rigid+flexible stems, thermocouple option, exposed capillary variants, multiple stem lengths
• Connector options: 6‑pin, 8‑pin and other electrical interfaces configurable

Applications

• High-temperature melt/process measurements (media temperature up to 400°C)
• Polymer production and melt processing plants
• Process installations requiring safety-rated pressure measurement (SIL2)
