CDL

Moreover, the star-shaped connection of the PM.NET digital network around the PRECIA MOLEN connection box (itself with IP68 and IP69K protection indexes) offers a direct connection of measurement equipment’s such as the weight remote display thus avoiding extra cabling to the indicator.
* Putting back into service in compliance with the present regulations, in France, an
Initial Repair Verification has to be performed every fortnight.

Immunity to high voltages

PRECIO MOLEN has developed a PM.NET field bus resistant to electrical disturbances thanks to a differential information transmission. The CDL has efficiently protected from electrical disturbances itself thanks to its high voltage clipping protections. Moreover, the connection of all grounded shielding in compliance with Electro-Magnetic Compatibility rules grants equipotentiality on the whole PM.NET network.

Totally waterproof
Due to its absence of detachable connection, this load cell is totally waterproof as proved by tests by a certified body. This load cell perfectly works in water for a prolonged time (IP68). Furthermore, the CDL can be cleaned by a high-pressure jet (IP69K) which eases the maintenance and sustainability of your weighbridge. Design Made of stainless steel, the load cell has in standard anti-rodent protection with metal sheathing offering efficient protection against rodent attacks. With its 125-mm height, this load cell is one of the most compacts ones in the market offering the renovation of older weighbridges simplifying civil engineering works..

Fields of use

• Weighbridges (trucks, wagons).
• Tank and silo weighing.

Description

With its 15 years’ experience in digital load cells, PRECIO MOLEN now offers the CDL, a compression digital load cell with mono column technology adapted to weighing applications for weighbridges. The CDL uses the measurement principle by distortion of beams submitted to a compression strain. It uses strain gauges mounted in Wheatstone bridges for the conversion of strength into an electrical signal. The CDL has been designed to be a little sensitive to load off-centering while keeping small dimensions. Made of Stainless Steel (304L), the CDL is waterproof in prolonged immersion (IP68) and high-pressure cleaning (IP69K)

Advantages

Digital technology offers measurement accuracy closest to the load to weigh, measurement conversion is performed within the load cell itself, the load cell sends a digital value. Therefore, the distance between the weighbridge and the indicator has no more influence on the quality of the information. So the 15-m long connection cable can be shortened according to installation requirements thus preventing cable strands under the weighbridge. Another advantage of digital technology lies in the set-up of a load cell network. The balancing of the weighbridge is performed more easily by a configuration of the load cell as opposed to a lengthy and delicate adjustment using potentiometers as in analog technology. All data are stored into the load cell but also in the indicator. Therefore, besides a fast detection of faulty weighbridge, replacing a load cell is easier as it only takes a transfer of all stored data into the new load cell for the weighbridge to be
instantly functional.*.
