Hydrostatic Resev. Sensor [LS-30]

 

Ronan Engineering抯 Model LS-30 Hydrostatic Reservoir Leak Sensor is designed to detect changes in liquid level within reservoirs of hydrostatic monitored double-wall tanks. Constructed of 304 stainless steel, polysulfone, Beryllium Copper and PVC, the LS-30 will provide years of trouble free service.

• Double Wall Fiberglass Tank Reservoir Monitoring
• Low and Low Low Level Monitoring
• High Level/Overfill Monitoring
• Vertical Application Dual Point Level Sensing

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抯 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抯 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.
