Frequently Asked Questions
What does "explosion proof" really mean?
Flameproof protection, or "explosion proof" as it's known in North America, is traditionally the most widely used method of protection for electrical devices in hazardous areas. The requirement is that the device's enclosure must be of significant strength and integrity to withstand an internal explosion of the harzard for which it is designed; without the explosion setting fire to the surrounding atmosphere.
What is "purged protection"?
Purging is a technique of applying a protective gas (possibly air) into an enclosure to prevent the formation of an explosive atmosphere inside the enclosure. This is accomplished by maintaining an overpressure against the surrounding atmosphere. Though this is a good method, typically used for control panels, it is limited in the sense that if there were a disaster or the pressurization system failed, the power from this device must be instantly removed rendering the device inoperative.
What are "IP ratings - Ingress Protection"?
There are two systems in common use for defining the amount of protection an enclosure affords against the intrusion or ingress of dust and liquids. The most widely used system is the IP code. This is defined fully in IEC 529. The NEMA Code system is often used in North America as an alternative to the IP code. Here is a reference sheet that gives NEMA codes and relates them to IP codes.
The IP code uses two digits to specify environmental protection. The first digit signifies the protection against solid matter (dust etc.) and the second digit specifies the protection against liquid (water). For your reference, here is a reference sheet that explains ratings in more detail.
How can I integrate SIDUS products into my system?
SIDUS offers a vast array of remote control options for our equipment. Standard configurations include analog voltages, RS-232, RS-422 or RS-485 via an easy to use Sidus protocol. Custom analog configurations and other common serial protocols such as Pelco-D are available upon request. Additionally, SIDUS also offers custom equipment controllers and graphical user interface software.
What is galvanic corrosion?
Galvanic corrosion is an electrochemical process where one metal corrodes when in electrical contact with a different type of metal. This type of corrosion commonly occurs when the metals are immersed in an electrolyte such as sea water. To prevent galvanic corrosion a non electrically conductive material is placed between the two dissimilar metals such as plastic or anodized film.
What are the various video formats?
Selecting the right video format for your application is key to a successful design. Questions such as; “Will I have a sharp, pixelated or small image? How much hard drive space will it take or bandwidth will it take to send it?” can only be answered after you have selected the image sizing required for your project. Attached is a link to help with your selection. Be aware some of these are very costly and are better for broadcast media or film makers. Video Formats
What are Incoterms?
Incoterms are an international standard of determining transportation obligations, cost and risks. It defines the “how” and “when” the transfer of ownership between a seller and a buyer occurs and who is responsible for the cost. For your reference, here is a quick reference sheet offered by the International Chamber of Commerce.
