LS-30靜壓水庫泄漏傳感器
The LS-30 can be installed to provide discrete indications of liquid increase or liquid loss, or provide high or low liquid indications. A breach of the tanks inner wall will allow reservoir liquid to escape the interstice into the primary tank, and a reservoir level drop will occur. A breach of the outer tank wall will allow reservoir liquid to escape the interstice into the environment, or ground water to enter the interstice, and a reservoir level change will occur. Liquid increase or loss, sufficient to move the sensor抯 float will transmit a signal to the control panel to initiate control functions or annunciate alarms.
Ronan LS-30 Sensor operates on a direct principle. Glass encapsulated, hermetically sealed, reed switches are embedded within the sensor stem. Permanent magnets within the sensor floats create a magnetic field which surrounds the reed switches. When a magnetic field is removed by movement of one or both floats, the reed switch is actuated, thereby changing state. This condition either opens a closed switch or closes an open switch. This change in state is then signaled to the control panel.
The LS-30 design allows rigid or flexible mounting for 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. The LS-30 may also be supplied with the optional RC-4 four inch riser cap assembly. The LS-30 is supplied with the low circuit N.O. and the high circuit N.C. Other logic configurations are available by specifying at time of order.
