FOXBORO FBM201d

FOXBORO  FBM201d   Controller processing module

The FBM201d Foxboro FOXBORO controller, due to the fact that the transmission time of this strain mechanical wave pulse signal in the waveguide is proportional to the distance between the active magnetic ring and the electronic chamber, can be highly determined by measuring the time.
The FBM201d Foxboro FOXBORO controller does not experience signal drift or variation, nor does it require periodic recalibration, as the output signal is a true signal rather than a proportional or amplified signal.
The high and low level reporting function of the FBM201d Foxboro FOXBORO controller and steam drum level gauge mainly uses the principle of magnetic stress to install magnetic switches at the upper and lower reporting points of the measuring float to detect the float. When the float reaches the low point, the magnetic field of the magnetic switch detects the magnetic field of the float, generating a fixed and strong mechanical wave pulse signal. The magnetic switch circuit sends out control instructions and determines it as a low liquid level alarm; When the float reaches the high point, the magnetic field of the magnetic switch detects the magnetic field of the float, generating a fixed and strong mechanical wave pulse signal. The magnetic switch circuit issues a control command, which is judged as a high liquid level alarm.
