LS-1立式液體傳感器

All LS-1 and LS-3 sensors have user selectable logic and may be installed in wet or dry conditions. Liquid collection or loss, sufficient to move the float will transmit a signal to the control panel to initiate control functions or annunciate alarms. The sensor design allows rigid or flexible mounting to allow easy periodic testing as required by many regulatory agencies. The sensor may be mounted loosely suspended by its cable or rigid with the 1/2 inch NPT nipple.

LS-3立式液體傳感器

Ronan LS-1 and LS-3 Sensors operate on a direct principle. A glass encapsulated hermetically sealed reed switch is embedded within the sensor stem. Permanent magnets within the sensors float create a magnetic field which surrounds the reed switch holding the switch closed. When the magnetic field is removed by movement of the float, the reed switch is actuated, thereby changing the state. This condition either opens a closed switch or closes an open switch. This change in state is then signaled to the control panel.
