Continuous level measurement in bulk solids

3. Selection of the measuring principle according to the application

Crusher

•Monitoring of crusher level •Strong abrasion ( non-contact) • High mechanical load ( non-contact) • Fast response times required • Vibration possible

B

Non-contact

Advantages

• Unaffected by the density of bulk solids, temperature, humidity, filling noise and weather impairment • Purge air connection is standard (FMR67B) • Easy installation with alignment facility •Remote access via Bluetooth® • Heartbeat Technology 2-wire (HART®, PA, Ethernet-APL) ±3mm/±0.12" –40 to +450°C/–40 to +842°F –1 to +16bar/–14.5 to +232psi 1.6 DN80, DN100, DN150, DN200, DN250, assembly bracket 125m/410ft

• Separate instrumentation recommended

• Attractive measuring point price • Self-cleaning effect of sensors, unaffected by build-up • Additional point levels, programmable • Robust sensor (vibration) • Easy assembly under conveyor belt derricks (overall size) and above the conveyor belt/crusher 2-/4-wire (4-20mA HART®, DP) ±2mm/±0.08", ±0.2% of measured distance –40 to +150°C/–40 to +302°F +0.7 to +3bar/+10 to +44psi — Threads, flanges (DIN, ANSI, JIS), wall and assembly arm, assembly bracket 45m/148ft
