Capacitive pressure transmitter LMK 351

ceramicthreadedG 1 1/2

Product description
The screw-in transmitter LMK 351 is designed for measuring small system pressure and for hydrostatic level measurement in containers. It uses an in-house capacitive ceramic sensor element with a flush-mounted diaphragm, enabling reliable measurement in viscous and pasty media. A PVDF pressure port and a pure ceramic diaphragm (Al2O3 99.9%) are available for aggressive media. An intrinsically safe version (Ex ia) is offered for hazardous areas.

Features

• Nominal pressure ranges: 0 ... 40 mbar up to 0 ... 20 bar
• Accuracy: 0.35% FSO (optional 0.25% FSO)
• Pressure port: G 1 1/2" suitable for pasty and contaminated media

Optional Features

• IS version (Ex ia) for gases and dusts
• PVDF pressure port for aggressive media
• Diaphragm: pure ceramic (99.9% Al2O3)
• Customer-specific variants
