Level transmitter DLT2 / DLT3

continuous

Application and function

The continuous level transmitter DLT2 / DLT3 is a level measuring system in conjunction with the
EC 8 level probe. The output current is proportional to the level (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: 
AD2000, EN61326-1, EN61010-1

Function of DLT2 / DLT3

The level transmitter DLT2 / DLT3 works in conjunction with the IGEMA EC 8 level probe, on the basis of the capacitive fill level method of measurement, whereby the dielectric properties of the medium are used.

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.

For the DLT3 applies:

If a programmed fill level is exceeded, the relay opens and thus enables the realisation of an overfill protection.

Technical basic equipment

• DLT2 in a plastic plug-in housing for easy fitting into switch cabinets
• quick fitting with a spring catch for the DIN EN 50022 standard 35mm carrier rail or for screw fixing on a mounting plate
