In automated feeding systems, one sensor does not always provide enough information to determine whether equipment should run.
Is there feed in the hopper? Is feed already present at the feed pan? By checking more than one condition before activating the equipment, the control system can make a better-informed decision.
The SCR SE series from dol-sensors is designed for applications where multiple capacitive sensors are connected in series.
When two or more sensors are connected in series, the output is activated only when all sensors are triggered. This makes it possible to verify two different points or conditions before equipment is activated.
A simple example is a feeding system with one sensor in the hopper and another in the feed pan. The feed auger can then be controlled based on the status of both sensors.
The result is smarter control that can help prevent empty running, unnecessary equipment wear and wasted energy.
The sensors are connected directly in series with the load and have no polarity requirements, helping simplify installation. Built-in overload and short-circuit protection add protection under demanding operating conditions.
For OEMs, the series connection option provides a simple way to add two-point or two-condition verification without unnecessarily increasing system complexity.
