Installed on suction pipeline or discharge pipeline of canned motor pump, and when liquid flow is broken for
canned motor pump, level switch will give out protection action signal, and signal type is normally close dry style
contact signal, normally close contact becomes normally open when protection action takes place.

Adopt ptlOO or thermocouple and furnished with temperature transmitter in option, mainly include:
A. Medium temperature monitoring: installed on the suction pipeline of canned motor pump to prevent motor
1nlet liquid temperature and Max surface temperature from surpassing allowable limit value;
B Stator winding temperature monitoring· installed in motor stator chamber to monitor stator winding
temperature;
C . Bearing temperature monitoring: installed on R.B. housing of canned motor pump to monitor medium
temperature in rear bearing chamber;
