LS-7卧式液体传感器
Horizontal Liquid Sensor [Model LS-7]
Ronan Engineering抯 Models LS-7s and LS-7s Horizontal Liquid Sensors are designed to detect the intrusion of liquid in dry interstice double wall fiberglass tanks, containment zones and caisson compartments where horizontal positioning of the sensor is preferred. The integral Pull-to-Test cable on the LS-7s, required in some jurisdicti***, allows sensor testing from ground level. C***tructed of PVC the LS-7 and LS-7s will provide years of trouble-free service.
The LS-7抯 unique design cannot be installed upside down as is the case with sensors from other manufacturers. Liquid collection sufficient to raise the sensor float will tran***it a signal to the control panel to initiate control functi*** or annunciate alarms.
The LS-7抯 thin cross section makes it ideal for applicati*** where limited vertical clearance is ***ailable. The sensor may be installed in any horizontal application where there is 0.625 inches of vertical clearance.
LS-7卧式液体传感器 Typical Applicati***
· Double Wall Fiberglass Tank Dry Interstice Monitoring
· Double Wall Piping Containment Sumps
· Horizontal Application Point Level Sensing
· Restricted Vertical Clearance
· Where Ground Level Testing is Required
Ronan抯 LS-7 Sensor operates on a direct principle. A glass encapsulated, hermetically sealed, reed switch is embedded within the sensor body. A permanent magnet in the sensors float creates a magnetic field which surrounds the reed switch holding the switch closed. When the magnetic field is removed by moving the float, the reed switch is actuated, thereby changing state. This condition opens a closed switch. This change in state is then signaled to the control panel.
