DOL 45 is a robust capacitive relay sensor designed for general detection of feed, grain, and solid materials.
The sensor provides great functionality and is easy to operate. DOL 45 can also be set up with no time delay, with delayed switch-off or switch-on and management for delay length. The time delay will start when the sensor is activated (switch-on delay) or deactivated (switch-off delay). The relay switches when the time delay expires.
A capacitive sensor is typically used as empty, full, and level indicator in tanks, silos, and containers. The powerful integrated relay means that DOL 45 can control many functions directly. The DOL 45 sensor has LEDs that indicate when the switches are activated. The sensor has NO (Normally Open) and NC (Normally Closed) outputs. All settings can easily be changed at any time.
The sensor is equipped with a range of special functions, which increase its usability:
The DOL 45 features a built-in powerful 5A relay with switch function. The sensor is available in two variants with the following voltage range: 10 – 30 V AC/DC or 90 – 250 V AC
The use of electronic rather than mechanical switches ensures unique reliability, particularly as the electronics are completely encapsulated in special plastic. This provides maximum protection against humidity and other external influences in harsh environments.
The sensor is CE, UL, and C-UL approved and has a high immunity to noise from electric communication (i.e. from a mobile phone) and transients (i.e. from motors and contactors). This makes the sensors very reliable.
The DOL 45 is easily mounted in a plastic gland, which is also available as a flange solution for easy external mounting. Likewise, the sensor is supplied with thread, providing several mounting options.
DOL 45 comes in a DOL 45R-T version. This model is specially developed for detection of feed supply in pipe conveyors, i.e. dry feeding systems and controlling feed transport systems. DOL 45R-T comes with the specially designed T-piece for mounting on a 40-60mm tube with conveying system using only the T-piece and three zip ties.

DOL 45 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 45 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 45 can still be adjusted eventhough the sensor has been mounted, which is not possible with normal sensors on the market as adjustment on DOL 45 is placed in the wire end of the sensor.
