Application and function
The DLT2 continuous fill level transmitter is intended for use in combination with the EC 8 level probe as a level transmitter for the output of an output current proportional to the fill level in the fluid tank (4 mA .. 20 mA).
It is intended for use in steam boilers or other fluid tanks.
The product meets EU Directive 2014/68/EU (PED).
Regulations applied: corresponding DIN EN standards.
Functioning of DLT2
The fill level transmitter DLT2 works in conjunction with the IGEMA EC 8 level probe on the basis of the capacitive fill level method of measurement whereby the electric conductivity of the medium is used. The conductivity of the medium is measured in µS/cm. For the secure functioning of this method a minimum conductivity of the substance to be measured is required.
Via the capacitive fill level method of measurement the continuous determination of the fill level is possible. The stored limits for low level (0%) and high level (100%) define the range for the determination of the current fill level. This value is converted into an output current at the 4mA .. 20mA power interface.
The transmitter supplies power to the level probe, which can be fitted into the tank, and evaluates its signal.
The 4mA .. 20mA output signal can be assessed at the terminals for further processing.
At an extra relay output the current output can be connected or a failure signaling can be attached.
