Pneumercator Non - Discriminating <br /> Liquid Float- Switch Sensors <br /> SECTION 2 . DESCRIPTION OF THE EQUIPMENT <br /> The basic function of the consoles is to provide both audible and visual warning <br /> alarms at the occurrence of high or low process condition via high/low level switches . <br /> The LS600 tank mounted sensing devices transmit alarm conditions by opening or <br /> closing dry switch contacts . Alarm conditions are indicated by red LED alarm lights and <br /> horn mounted on the console . <br /> The standard liquid switch sensors used with the consoles are the Model Series <br /> LS600 liquid float-switch sensors . These switches consist of from one to four magnetic <br /> cylindrical floats mounted on a brass or stainless steel tube suspended into the top of a <br /> liquid storage tank . Each float actuates a switch when the liquid level rises or falls past <br /> the float . When the switch is actuated the alarm is activated . <br /> Another device that can be interfaced to the consoles is the LS610 , which <br /> consists of a flat float that swivels up and down on a square shaped body . The float <br /> actuates a switch when the level rises to a certain level activating the alarm . <br /> Page 2 of 8 <br />
