Camaweigh Junction Boxes

A junction box, in general, is a type of enclosure wherein two or more electrical connections meet. Junction boxes can either be enclosed or open, but for most occasions and purposes junction boxes are covered in order to protect the connections. A Junction box need to be very durable and withstand stand several external extremes to ensure the safety of the wirings inside. Junction boxes are used mostly for industrial uses, especially in the weighing industry. A junction box is alternately called a summing box since is it used for taking multiple input connections and producing a single output.

Junction Boxes in the Weighing Industry

Junction Boxes are very applicable in the weighing industry specially being used with their load cell devices. Many types of weighing equipment make use of multiple load cells. Most notably, vehicle weighing equipment like weighbridges and dynamic load axles all have more than one load cell. Since each load cell has its own weight reading, the outputs need to be summed up to get the total weight of the truck or vehicle. In order to do this, each load cell is wire into a junction box or summing box where it meets all the inputs from the other load cells. This is where they are added up and a single output electrical current is transferred to scale indicator displaying the result. A load cell junction box does not only sum up the inputs of load cells but it has the ability to monitor the function of a load cell and increase its speed.

Types of Junction Boxes

Camaweigh offers junction boxes from different manufacturers and also their very own OEM brand. Camaweigh’s junction boxes provide safe and swift application of weighing into any system. Junction boxes are very critical in the overall efficiency and output of weighing equipment which use multiple analog load cells. Camaweigh junction boxes are guaranteed to last for a long time and are very easy to install. Junction boxes can be made depending on the connection requirements of the user. If they are in need of a junction box which can accommodate 4 input connections, Camaweigh can provide. Camaweigh offers junction boxes with up to 8 input connections. You can choose from either plastic or stainless steel junction boxes. The stainless steel variant offers 4 to 8 input lines. For the plastic variant the available number of input lines is 4 to 6. Camaweigh’s junction boxes have IP68 international standard rating which means it is protected against dust, dirt, sand, and water. It can be submerged in water for 30 minutes for up to 1.5 meters deep. Camaweigh’s well-built junction boxes are also resistant to moisture and are equipped with surge protection. Weighing equipment, especially weighbridges and dynamic axle weighing scales, are mostly located and installed in open areas. In industries like mining and excavation, vehicle weighing equipment is always subject to all the harsh weathers. They are prone to lightning strikes which can cause massive electricity service which can cause potential damage to the junction boxes.

Every junction box or summing box excites voltage to each load cell and transfers their individual performance characteristics and weight results to the weighing instrument. Each load cell has sensitivity error which can be minimized when connected to the junction box. Camaweigh also offers its clients the option where they can customize their own junction boxes based on their application requirements. Standard junction box circuits have a minimum of up to four input lines and a single output line. This output line is usually connected to a single scale indicator. In the case where the output of the junction box is desired to be displayed on more than one scale indicator, Camaweigh can customize a junction box capable suitable for this function.
