1. General Information :
1.1. Material Acceptance
Check that there is no damage on the packages during the transportation immediately after the material acceptance. If packages are
damaged, open the packages immediately and check whether products are affected or not, if there is any damage, send your
complaint report to the transporter company and its photocopy to the address of our company.
1.2. Information about Areas of Use
ELT series single vibrating material level switch is one of the tuning fork material level switches. It is not afraid of hanging materials, not afraid
of impact, without clamping problems, and has higher sensitivity.Its cylindrical single measuring rod structure determines its wider
adaptability to industrial field.
Areas of Application :
Sugar, Hazelnut, Clay, Sunflower Seed, Coffee, Various Granules, Wheat, Bauxite, Ceramic, Legumes, Cereal, Fish Feed, Sand, Pebble,
Isolation Materials, Corn, Rice ...
Ambient Conditions: Relative Humidity: 5-95 %RH Ambient temperature: 60 °C (It is not used under -5 C)
1.3. Working Principle
Single rod vibrating level switch uses the "resonance" principle of tuning fork to generate vibration
under the driving of piezoelectric elements.
Only when all around the probe rod are surrounded by materials, the vibration amplitude will be
sharply reduced, resulting in switch action.
