This kind of sensor is designed and mounted on MLG-33/44/55 to switch point of interest. Switching system of this sensor is SPDT and self –sustaining. It should be fixed around level gauge's body by special clamp. Be careful, 2cm of surface can be controlled by MS15 and for more controlling, two sensors should be used.
Level Gauge Sensor-MS15
Magnetic Level Gauge MS15 install next to the Level Gauge. When the floater goes up exist magnetic field and finally change to the micro switch.
Magnetc Level Gauge MS15 installed to the body of Level Gauge and fix by clamp curve.
