Excites the oscillating element of the density transducer to
its natural frequency.
Equipped with a two-line display and four keys for displaying
data and configuring the on-site transmitter.
HART
communication
When the process data are changed, the user can perform a
simple modification of the set parameters.
Density, concentration, operating temperature, etc.
Lower range and upper range value of the output signal
(smallest measuring span approx. 5 kg/m³)
Calibration constants, constants of liquid, reference
temperature, etc.
