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
The DX-ELT vibrating level switch is one of the other types of level switches. Unlike other sensors, it is not affected by the sticking of materials
on the probe and impacts. It has no jamming problem and has a high sensitivity range.
Ambient Conditions: Relative Humidity: 5-98 %RH Ambient temperature: 60C (It is not used under -20 C)
1.3. Working Principle
DX-ELT series sensors generate vibration by means of piezoelectric elements using the resonance principle. Only when solid particulate materials
or liquids surround the probe, the vibration frequency drops drastically, resulting in the output signal.
Application Areas:
It can be used in process that containers , silos , free flowing dusts, granules and various types of small particule solids such ascereals,
beans, edible oil process, sugar, animal feed, rice plants, detergents, dye powder, chalk, gypsum, fly-ash, cement, sand, plastic granules, spices,
milk powder etc.

*Then, apply below mentioned explanations according to structure of the design.
2.3. Special Notes
*Please ensure that there is no mechanical stress on the shaft following installation. Such case will cause slipping in thecharacteristic curve.
*vibrating level switch must be placed upright or horizontal.
*Allocate valve certainly in the process connection while instrument is used.
*Allocate blowdown valve under bottom flange for blowdown.
*If instrument is mounted outside and if there is any danger of lightning or
excessive pressure, take preventive measures by taking necessary measures.
*In the operating conditions, vibrating level switch may be hot according
to situation of fluid, in this case, do not touch the indicator, otherwise your skin is damaged.
*The grounding product must be done properly. (can be done outside or in housing)
2.4. Installation For Mechanical Connections
*Use appropriate O-Ring or gasket for tightness.
*Ensure that its surface is clean and smooth.
*Assemble the instrument manually.
*Connect the contacts as shown in the figure.
