27L series includes Float Reed level transmitters. Inside the float is placed a toroidal magnet which drives, without contact, Reed contacts located inside the guide pipe.
Moving along the guide pipe the float changes the reed contact status. These variations are then acquired by the electronic board and converted into a current signal.
This system enables a continuous level measurement (output 4 ÷ 20 mA) with high repeatability and linear level indication independently from tank shape or allows to realize on-off controls by using two floats (output On – Off 5 ÷ 15 mA).
Reed chain replacement can be done without dismantling the transmitter from the process and doesn’t need any recalibration.
As an option, it is possible to do a PT100 installation in order to get the local temperature of the fluid.
27L series transmitters are used in marine and industry for level detection of liquids tanks. The measurement is not affected by parameters such as conductivity, pressure, temperature, viscosity, tank shape, etc. Our technical office is at your disposal for special applications.
