Side Mounting Float Switch for Septic Tank Level Control

Features:

SJE SF2™ float switch is a suspended float switch designed to monitor levels in nonmagnetic tanks (e.g. of stainless steel or plastics). Thanks to the "Flexible Connection Float" technology, it can avoid the interference of the dirties, thus it is very suitable for use in extremely dirty liquids, like septic tank . 

The switch body mounted on the side wall of the tank with the G¾" screw sleeve. A plastic float suspended on the end of a stainless steel cord. Float and cord are inserted in the tank through a G¾" screw plug. As the float rises with the level of the liquid, a permanent magnet inside the float actuates the magnetic switch inside the G¾" screw plug, providing an upper or lower level signal . 

Switching points are provided 10±5 mm below or above the centre line of the G¾" screw plug. A special plastics sealing ring protects the G3/4 screw plug against the thread of the welding sleeve. Thus, only a little sealing material is required when first time installation.


•   No jamming of the freely movable float .
•   Suited for extremely dirty liquids, e.g. septic tank, oily wastewater.
•   Easy installation. Only a little sealing material is required.
•   High precision magnetic switch design.
•   Integral watertight cable (comply with TJ/CL254-2013(V1.0).
•   Registered utility model
•   Tested according to EN 50155 (approved for use on rail vehicles)

LCD Screen

brightness
LCD is a substance between solid and liquid. It can't emit light by itself, so it needs additional light source. Therefore, the number of lamps is related to the brightness of the Liquid Crystal Display. The earliest liquid crystal displays had only two upper and lower tubes, the lowest of the popular type was four lamps, and the high-end one was six lamps. The four-lamp design is divided into three types of placement: one is that there is a lamp on each of the four sides, but the disadvantage is that there will be dark shadows in the middle. The solution is to arrange the four lamps from top to bottom. The last one is the "U"-shaped placement form, which is actually two lamp tubes produced by two lamps in disguise. The six-lamp design actually uses three lamps. The manufacturer bends all three lamps into a "U" shape, and then places them in parallel to achieve the effect of six lamps.
Tip: Brightness is also a more important indicator. The brighter the LCD, the brighter the LCD, it will stand out from a row of LCD walls. The highlight technology we often see in CRT (ViewSonic is called highlight, Philips is called display Bright, BenQ is called Rui Cai) is to increase the current of the shadow mask tube to bombard the phosphor to produce a brighter effect. Such a technology is generally traded at the expense of image quality and the life of the display. All use this The products of this kind of technology are all bright in the default state, you always have to press a button to implement, press 3X bright to play the game; press again to turn to 5X bright to watch the video disc, a closer look is blurred, you need to watch The text has to be honestly returned to the normal text mode. This design actually prevents you from frequently highlighting. The principle of LCD display brightness is different from that of CRT. They are realized by the brightness of the backlight tube behind the panel. Therefore, the lamp has to be designed more so that the light will be uniform. In the early days when selling LCDs, it was a great thing to tell others that there were three LCDs. But at that time, Chi Mei CRV came up with a six-lamp technology. In fact, the three tubes were bent into a "U" shape. The so-called six; such a six-lamp design, plus the strong luminescence of the lamp itself, the panel is very bright, such a representative work is represented by VA712 in ViewSonic; but all bright panels will have a fatal injury , The screen will leak light, this term is rarely mentioned by ordinary people, the editor personally thinks it is very important, light leakage means that under a completely black screen, the liquid crystal is not black, but whitish and gray. Therefore, a good LCD should not emphasize brightness blindly, but more emphasis on contrast. ViewSonic's VP and VG series are products that do not emphasize brightness but contrast!
