Bin Level Indicator Offers Reliable Readings
Dol-sensors is a Danish business that sells capacitive and proximity sensors for detecting feed and grain levels in bins.
    The company has designed, produced, and marketed intelligent capacitive, climate, and management sensors for over 50 years. These sensors work with grain, feed, wood, plastic, and other granular materials, making them well-suited for livestock houses, materials storage for plastics production, and wood stove pellets. The extensive product range includes smooth cylindrical, threaded cylindrical, and flat sensors.
    Agriculture sensors have unique requirements compared to other models. They must withstand high humidity, dust particles, extreme temperature swings, and high ammonia concentrations. Consequently, each sensor is built with robust housing and filters. They’re made without moving parts; most are IP 67 or IP 69K for dust and moisture protection. The climate sensors come with protection caps to protect against high-pressure cleaning. Likewise, most are certified to ensure a long lifespan.
    The DOL 44 and iDOL 44 are 30 mm capacitive sensors that work to detect feed, grain, and other solids. They’re well-suited for level control in silos and containers and can help control the filling and emptying process. Each sensor is easy to operate and adjustable with a smartphone or by changing the setting via two trimmers accessed with a screwdriver.
    The DOL 44 and iDOL 44 are highly immune to noise from electric communication like mobile phones. They both have full temperature compensation, and the sensors are robust regarding washing and EMC protection, making them possible to use in environments with frequency converters. A red LED light indicates the relay sensor’s current status to ensure you know when it’s working.
    The sensors should work for years without maintenance. The iDOL companion app, SmartAdjust, makes operating them easier than other capacity feed sensors. 
    Ted Smith of Alberta, Canada, has found the sensors to be an upgrade over standard options. “Some mechanical bin full indicators must be mounted on the bin roof. They can be hard to see, especially at night. These sensors take the guesswork away.”
    He also praises how easy they are to manage. “You can fine-tune the sensor’s sensitivity via NFC or Bluetooth to your phone, but mine worked right out of the box. No moving parts means the sensors are very reliable. You can even attach them to strobe lights or sirens to make them easy to notice (assuming you have power onsite). The sensors can also control augers to automate operations, say, for grain drying or feed processing.”
    The in-house R&D team at Dol-sensors makes it possible to request custom versions designed to meet specific needs in small batches. Reach out directly to learn more.
