NEW-FLOW VLS5000 Vibrating Level Switch
The NEW-FLOW VLS5000 Vibrating Level Switch uses an energised tuning fork for point-level detection in process liquids. The fork vibrates at its mechanical resonant frequency; immersion in liquid changes the vibration and produces an SPDT switching output. It can support high- or low-level alarms, pump control and process interlocking when the selected connection and wetted materials are compatible with the application.
Key Features
- Tuning-fork point-level detection
- Threaded, flanged, clamp and coupling process connections
- Standard or extended insertion lengths
- IP65 and explosion-proof enclosure classifications stated in the attached datasheet
- SPDT output for alarm and control duties
