LS-6/LS-7 Single-Point Level Switch
Brand: Gems Sensors, Inc
The LS-6 is a very compact level switch that protrudes into a tank less than 1-1/2". Polypropylene and stainless steel wetted parts provide broad chemical and potable water applications.
An SPDT relay enables this LS-7 to control two independent loads up to 5 amps each. Switching N.O. for one load and N.C. for the other. This unit is designed to operate with a load connected to each of the two outputs.
These loads must be 10 watts, minimum, for correct SPDT switching. One load used alone must be connected to the N.O. terminal. With this load, which may be less than 10 watts, the unit will operate the same as an SPST unit.
