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
It provides automatic driving of equipments that control the liquids in the tank (such as pump, hydrophore and solenoid valve).
It must be used in the permitted usage environment and application areas!
It is not used in corrosive environments, explosive and combustible environments.
Compatibility with the medium to be measured should also be considered.
In case of improper use, modification and damage, no liability is accepted and these cases are not covered by the warranty.
Ambient Conditions: Relative Humidity: 7-70 %RH Ambient temperature: 70 °C (It is not used under -10 °C)
1.3. Working Principle
SK-P Level control device is used together with level sensors. When magnetic field of magnet within the buoy moving along tube
according to liquid level comes up to the reed sensor, it opens or closes the electric circuit. Such changes and alarm or level information of reed
sensors can be evaluated with SK-P control device.
Automatic control has been provided by sending signal to solenoid valve bobbin or contactor of engine through relay output. Furthermore,
it is possible to receive signal or warning with light through a relay for the purpose of alarm.
This circuit can be controlled through an additional
button manually
