The M3850 is a small, low-cost conductivity level sensor designed for food applications in metal-walled tanks or vessels. Installation is simple, and multiple units can be wire together in phase so that multiple tank level points can be detected. All materials are food-grade, and the contours of the insulator shell meet NSF requirements for cleaning.
While a conductivity switch and a float-type switch perform the same functions, the advantage of no moving parts is that the conductivity switch can be used in several environments that would cause a float to stick or to not operate at all. The probe is mounted with an insulator shell for sensing in such liquids. With no moving parts, switch operation of the M3850 is not ...
Reverse polarity, over voltage, short circuit and transient protected
These compact optical switches incorporate a phototransistor that provides a digital output indicating the presence or absence of liquid. The sensor tip houses the phototransistor. The refractive index is changed when covered by liquid, thus indicating the level.
There are several wetted materials and operating ...
