Conductivity Switches for Heavy Bodied and Semisolid Liquids

M3784 Series: Conductivity Switches for Conductive Liquids

Madison supplies a basic controller with the M3784 that will satisfy a broad range of applications. Because the conductivity varies widely among liquids, the controller is adjustable for sensitivity in different liquids. Consult factory for details on specific liquids.

While a conductivity switch and a float-type switch provide 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. These would include semisolid liquids like food industry and industrial slurries or heavy-bodied liquids like wastewater. With no moving parts, switch operation of the M3784 is not interrupted.

Only an extremely small amount of current is necessary for the unit to perform. As with any device, a properly installed and grounded system poses no electrical hazard.

M3850: Single-Point Probe Sensor for Food Applications

The M3850 is a small, low-cost sensor designed for food applications in metal-walled tanks or vessels. Installation is simple, and they can be wired in phase so that multiple 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 l iquids. With no moving parts, switch operation of the M3850 is not interrupted.
