  • Testing the Mettle of Metalic and Non-Metallic PLC Enclosures

    At the heart of today’s automated manufacturing operations are programmable logic controllers (PLCs), which are miniaturized computers installed throughout a factory floor. These devices receive input from sensors throughout the line and use that data to issue commands to control machinery operations. Though PLCs are individually protected in rugged casing, they often are ganged together in enclosures specified according to application-specific needs.

  • Pentair Offers Non-Metallic Trough Applications

    Contractors building raceway and running wires in corrosive or hazardous environments might opt for non-metallic trough. Examples include infrastructure work such as roads, bridges, tunnels or airports and commercial applications where chemical, dust or corrosion resistance is needed. Other markets include indoor manufacturing operations, water and wastewater applications. Salt-water or marine applications such as off-shore oil drilling are other applications, as is mining and large construction.

  • Helping PLCs Keep Their Cool

    Programmable logic controllers (PLCs) are the ruggedized computers that run most automated manufacturing processes, from simple conveyor lines and pick-and-place operations, to more sophisticated machining and robotics applications. Though individual units are often quite small, PLCs are often installed in ganged enclosures and, like other types of computer equipment, they can produce a lot of heat. As a result, specifiers and contractors need to consider cooling options to protect against equipment overheating and failure.

  • Sensing Becomes an Opportunity in Latest Energy Codes

    Occupancy and vacancy sensors are set to become significantly more important elements in commercial electrical designs over the next several years, thanks to increasingly stringent efficiency requirements in state and national energy codes. As a result, electrical contractors should take some time to understand the latest code updates and the products available to meet new demands.

  • Keeping Current on Voltage-Testing Options

    Among the most basic tasks for electrical contractors is testing for the presence – or absence – of electrical voltage. Whether it’s simply to determine if a system is de-energized and safe to work on, or part of a more complicated troubleshooting exercise, voltage testing is a critical element in any contractor’s job. Choosing the right tester can be more than an issue of convenience, it also can make a difference in an electrician’s productivity – and, more importantly, safety.
