iDOL 44 Intelligent Capacitive Sensor

dol sensors

DOL 44 is a 30 mm capacitive relay sensor for detection of feed, grain, and solids with relay output including switch function. The sensor is applicable for level control in silos and containers along with controlling the filling and emptying process.

Different Variants for Different Needs

DOL 44 is available in a multitude of versions, such as the DOL 44RH with integrated heater for cold and/or high humidity applications avoiding condensation. DOL 44RT for detection of feed in tubes, and DOL 44R-33 with conical 30/32 mm enclosure.

Robust Functionality

DOL 44 has a high immunity to noise from electric communication (e.g. mobile phones) and transients (e.g. from motors and contactors). The IP69K protection class offers the highest protection against water and other liquids, e.g. during cleaning of livestock houses.

DOL 44 has full temperature compensation, and the sensor is very robust in regards to washing and EMC protection.

The sensor can, therefore, be used in environments with frequency converters.

Easy to Operate

The sensor has robust functionality and is easy to operate. Settings are easily changed via two trimmers using a small screwdriver.

A red LED light clearly indicates the current status of the relay sensor.

Flexible Mounting

This sensor comes with smooth or threaded housing and with T-piece for mounting on a 40-60mm tube with conveying system.

DOL 44 can be mounted inside a feeder or through a hole into a feeder, a hopper, or a silo with the included plastic gland.

With the specially designed T-piece, DOL 44 can be mounted on a 40-60mm tube with conveying system using only the T-piece and three zip ties. With this mounting option, DOL 44 can still be adjusted even though the sensor has been mounted, which is not possible with normal sensors on the market as adjustment on DOL 44 is placed in the wire end of the sensor.

The sensor is also available in variants with integrated heater for cold and/or high humidity applications to avoid condensation.

Low or high voltage

DOL 44 with low (10-30V AC/DC), high voltage (90-265V AC) or universal voltage (20-280V AC/DC) is a 30 mm relay sensor with trimmers placed vertically.

Conical housing

DOL 44 comes with conical housing – 30 mm at the end and 32 mm at the buttom (wire end).

The Future of Relay Sensors

The iDOL 44 is the future of relay sensors. These sensors have NFC and are adjusted via the SmartAdjust App. This allows for more parameters to be available for the user, compared to a traditional sensor with two trimmers operated by a screwdriver. The result is a more flexible sensor, which can be adapted to the individual need of the user.

The app makes it possible to do more with one sensor. For example, you can configure your iDOL sensors to have on/off delay and Max Run Timer at the same time. It is possible to copy settings to multiple sensors allowing you to preconfigure sensors with same settings before installation.
