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
ELC level switches are used for checking liquid level of tanks and boilers. As it does not have any movable part, it can be used in the
critical ambient and in the liquids with solid particle, low density and high viscosity.
lt is an economic and safe solution for air pressure tank applications, water level control of steam boilers and conductive tanks.
Ambient Conditions: Relative Humidity: 5-95 %RH Ambient temperature: 50C (It is not used under -5 C)
1.3. Working Principle
When liquid leved comes to the level of isolated electrode, current passage starts or stops between electrode and
liquid. Strengthened this AC current may be assesed with a relay cirruit.
1.4. Technical Specifications and Pictures:
All dimensions are given in mm.
