Sick LFP1200-G1NMB Overview
HYGIENIC LEVEL PROBE
Sick LFP1200-G1NMB Description
- Level monitoring in hygienic applications
- Manually cutable monoprobe up to 2,000 mm long with Ra ≤ 0.8 m
- Process temperature up to 150 C, process pressure up to 16 bar
- CIP/SIP resistant
- IP 67 and IP 69K enclosure rating
- Interchangeable hygienic process connections
- 3-in-1: combined display, analog output and binary output
- Analog output 4 mA ... 20 mA / 0 V 10 V, switchable, plus two binary outputs
- Robust design increases service life
- High flexibility due to cutable probe and interchangeable connection concept
- Cost savings due to multiple output signals: one system for both level detection and continuous level monitoring
- Time and cost savings due to low maintenance and quick commissioning
- No calibration or recalibration required for commissioning, thus saving time and costs
