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.
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. 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 10 A relay with switch function. The sensor is available in two variants with the following voltage range: 10 – 30 V AC/DC 90 – 250 V AC
The use of electronic rather than mechanic switches ensures a 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 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 is part of the DOL 40 series which is a series of robust capacitive/proximity sensors designed for general detection of feed, grain, and solid materials.
The DOL 40 series provides great functionality and is easy to operate. The series includes three models with different functions: DOL 41, DOL 43, and DOL 45.
By means of a new microcomputer technique all functions have been put together in one sensor – the DOL 45.
Apart from the two other options (DOL 41 and DOL 43) the DOL 45 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.
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. The setting of sensitivity is more accurate, and the factory preset is 15 sec. delayed switch-on. The time delay starts when the sensor is influenced. When the delay expires, the relay switches. It does not switch back again when the influence stops.
