Abstract:
Provided is a pressure tight, explosion-proof connector that allows different types of sensors to be attached using a common connector and that obviates the need to perform repairs on the individual sensor level. A canned motor pump (10) has a centrifugal pump (11), a stand (12) for supporting the body, a motor (13), a bearing holder (14) for the motor (13), a terminal flange (15) attached to the external cylinder of the motor (13), a terminal box (16) attached above the terminal flange (15), a motor monitor (17) attached above the terminal box (16), and a pressure-tight, explosion-proof connector (20) attached to the terminal flange (15). The pressure-tight, explosion-proof connector (20) has a base coupling (21) attached to the terminal flange (15), and a connecting cylinder (22) connected to the base coupling (21). A pressure sensor (23) is connected to the tip of the connecting cylinder (22).
