    DOL Capacitive Sensors Now ATEX Approved

    The popular capacitive sensors in the DOL 40R series from SKOV A/S are now available with ATEX approval. The sensors are certified for zone 20 – areas with constant danger of dust explosion.

    On the 1st of July 2003 the European ATEX directive comes into force. It includes all mechanic and electric equipment, which is used in potential explosive areas. Here static electricity can trigger off explosion fires. But the new ATEX approved 40R series increases the safety. The series has been tested and approved by independent laboratories and is designed for usage inside containers – e.g. with grain, feed and granulated material – where there is risk of dust explosion. The sensors in the DOL 40R series even have their own amplifier and change-over relay, so no additional ATEX approved equipment is required. The models in the DOL 40R series are already CE and C-UL approved.

    Reliable and Resistant

    The DOL 40R series is extremely reliable. For example it uses electronic rather than mechanic switches. Likewise, the electronic is embedded in special plastic, which makes it extra resistant to outer influence in aggressive environment. Finally the series is extra immune to transients (e.g. from motors and contactors).

    Easy to Mount

    All the sensors are delivered in an Ø30 mm cover, which is dust- and waterproof. The sensor is easily mounted in an ATEX gland, which creates electric connection to the mounting surface via a conductive packing. From here it is easy to earth the installation.

    Flexible and User-friendly

    The DOL 40R series offers the same flexible functionality and user-friendly operation, for which all DOL sensors are known. The enclosed instructions guide the user easily through the programming sequence. Sensitivity and delay period is set by means of two press buttons. Light-emitting diodes indicate when the press buttons are activated. The series is available with or without integrated timer, and can be delivered in two voltage areas, namely 10-30 V AC/DC and 90-230 V AC.

    Specialist and Market Leader

    SKOV A/S is a specialist in developing electronic sensors for agricultural and industrial purposes. The company is leading on its market, and has for more than 25 years developed the series of DOL sensors, which are very much in demand. This is especially due to the fact that SKOV A/S develops the sensors in close collaboration with the customers. Experiences made in the harsh operative environments of agro industry benefit the other areas of industry. Not only do the products comply with current standards, but are in a number of cases enhanced to be able to function flawlessly in all types of environment.
