Vertical Liquid Sensors [Models LS-1 and LS-3]
Ronan Engineering抯 Models LS-1 and LS-3 Vertical Liquid Sensors (and the variati*** LS-3s and LS-3ss) are designed to detect changes in liquid level within reservoirs or the intrusion of liquid in dry containment zones and caisson compartments where vertical positioning of the sensor is allowed. Both the LS-1 and the LS-3 are c***tructed of 304 and 316 stainless steel, polysulfone, Buna-N and PVC. The LS-3s includes an integral Pull-to-Test cable, required in some jurisdicti***. The LS-3ss Sensor is c***tructed of 304 and 316 stainless steel and Teflon, and is designed for use in chemical applicati*** where corrosion is a concern. All LS-3 sensors are designed to provide years of trouble-free service.
LS-1 或 LS-3立式液体传感器Typical Applicati***
· Double Wall Steel Tank Interstice Monitoring
· Piping Containment Sumps
· Sub-pump Containment Sumps
· Fill Riser Containment Sump
· High Level/Overfill Monitoring
· Vertical Application Point Level Sensing
· Where Ground Level Testing is Required
· Corrosive Chemical Monitoring
All LS-1 and LS-3 sensors h***e user selectable logic and may be installed in wet or dry conditi***. Liquid collection or loss, sufficient to move the float will tran***it a signal to the control panel to initiate control functi*** or annunciate alarms. The sensor抯 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.
Ronan抯 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.
