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
Level Transmitter is designed for industrial plants. It should never be used in mines.
Otherwise, the responsibility of the manufacturer is eliminated.
Tank level measurement and control,boiler kontrol,store room control..
Ambient Conditions: Relative Humidity: 0-98 % RH Ambient temperature: 60 °C (It is not used under -20 °C)
1.3. Working Principle
DX-ELS-tx level transmitter are used for tank levels and for controls. In the float when the magnet magnetic area moves according to the
liquid in the tube, then the reed swicthes the electrical circuit on or off when it reaches the level of the sensor.Reed swicthes in and out.
The changes of the reed sensors with alarm or a level information can be assessable with a relay circuit or a control device.Sensitivity increases
according to reed sensor lowering range.The advantages of providing the analog output in the enclosure are preferred by the users.
1.4. Reed Relay and Operation Conditions

Inductive Load
Capacitive Load
When reed switch is used for loads such as electromagnetic relay ,contactor or solenoid, reed switch may be exposed to very high
voltage depending on value of inductive load. This causes either failure of switch or shortening its service life. Therefore, it is
recommended to be used as follows depending on used voltage, for the purpose of protection of switch.
When reed switch is used with capacitive load, it may cause that high current passes over reed switch, depending on value of
capacity during Charge '96 Discharge of capacity. So this may cause failure of switch. It is recommended to be used as follows
depending on used voltage, for the purpose of protection of switch.
