DOL Sensors Parts

For Automation of Processes

DOL Capacitive sensors are used for the automation of processes where there is a need for controlled conveyance and storage of materials. The capacitive sensors ensure an efficient and seamless handling of grain and other feedstuffs, among other things, but can also be used for handling wood, plastics and other granular materials.

The capacitive feed sensors ensure an efficient and seamless handling of grain and other feedstuffs, and can be used for handling wood, plastics and other granular materials.

The range includes both smooth sensors and sensors with screw threads.

• Detection of feed and grain in feed systems for livestock production
• Large range of functional, mechanical and electrical variants to meet every need
• Designed for aggressive livestock house environment

Dol 20 Series

The Capacitive Sensor is designed for general detection of solid and loose materials. The sensor has potential-free relay contacts with a switch function.
The product is intended for contactor operation but will be well suited for a number of other agricultural and industrial applications.

Dol 25 Series

DOL 25 is connected to a central control unit or directly to a control relay. The types with integrated timers are particularly suitable for the direct control tasks.

There are three basic types, which differ concerning functionality, operation and number of trimmers. The sensor with one trimmer has adjustable sensitivity and the sensor with two trimmers has both adjustable sensitivity and adjustable off-delay timer.

TECHNICAL INFO

Dol 40 Series

The DOL 40R series of Capacitive Sensors provides great functionality and is easy to operate. The series includes three models with different functions.

DOL 41R has no time delay. The relay switches as soon as the sensor is activated and remains in this position until the activating influence stops.
DOL 43R has an option for delayed switch-off. When the activation stops, the time delay starts. When this delay expires, the relay switches back.
Apart from the two options above the DOL 45R can also be set for delayed switch-on. The time delay will start when the sensor is activated. The relay switches when the time delay expires. The relay will not switch back until the activation stops.
