PRODUCT OVERVIEW
The Auto-Set™ series RF capacitance point level monitors are used for detecting high, intermediate, or low
levels of liquids, powders and free owing granular solids stored in tanks, bins, silos or other containers.
The Auto-Set series incorporates simple push-button calibration with microprocessor enable/disable switch
for total protection of stored values. Once the Auto-Set is calibrated for the application it never has to be
re-calibrated. Data is stored in non-volatile memory so it is not aected by power loss.
A four digit LED display shows set values for uncovered, covered and trip settings, allowing simple set-up
and adjustment. A set of voltage-free changeover relay contacts are actuated when the level of the material
in the container reaches the probe. The unit incorporates a unique power shield which automatically
compensates for material build-up around the probe and on the sides of the container, preventing false
indication. The solid state electronics are housed in a weatherproof, glass-reinforced nylon enclosure.
The Auto-Set series can be top or side mounted, and are available with 220 mm, 320 mm, 1 meter and 2
meter (3, 12, 24, 36 and 48 inch) 303 solid stainless steel probes. For applications up to 10 meters (33
feet) long (maximum), 303 stainless steel wire is used to extend the probe length. The Auto-Set can be
used with container walls up to 368 mm (14.5 inches) thick (see specications).
The ush probe version (ATS8V0AI-FP) is designed for plug condition monitoring within tight tting applications.
It has a built-in mounting ange, and the probe can be inserted 32 mm (1-1/4 inches) (minimum) into a
tank or spouting with container walls up to 20 mm (3/4 inch) thick. For container walls thinner than 20 mm
(3/4 inch), the probe can be inserted farther.
For high temperature and/or high vibration applications, a remote Auto-Set version is available. Contact
4B for more information.
