Operating principle

SITRANS FM TRANSMAG 2 is a microprocessor-based transmitter with a built-in alphanumeric 
display in several languages. The transmitters evaluate the signals from the associated 
electromagnetic sensors and also fulfil the task of a power supply unit which provides the 
magnet coils with a constant current.  

The magnetic flux density in the sensor is additionally monitored by reference coils. Further 
information on connection, mode of operation and installation can be obtained from the sensor 
data sheets.
