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.
11.2. 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.
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.

Probe Does Not Produce
Resistance Output
- Liquid might not be contacted.
- Plugs of the probe might be too relaxed.
- There migh be a break in process wire.
- Probe might be dissolved due to chemical substance.
- Liquid contact should be checked.
- Plugs should be checked.
- Process wire should be checked.
- Contact with the manufacturer.
High Resistance Output -Probes have short-circuited
- The wires used in process is not suitable
- Dirt has stacked on probes due to maintenance neglect
- The nut on probe thread have overly screwed
inside of housing
- Proper connection cable should be used.
