Combustible Dusts are a known hazard in a number of industrial fields. Recognizing dust as a potential hazard and taking the steps to mitigate the risks present are critical to the safety of your facility. The recently updated NFPA® 652: Standard on the Fundamentals of Combustible Dust is a useful resource for addressing combustible dust hazards and conducting a dust hazard analysis (DHA) within your facility.

2018 is yet another award-winning year for ecom, a Pepperl+Fuchs brand and manufacturer of mobile devices for intrinsic safety. The Weltmarktführer (WMF) Index has named ecom a World Market Leader Champion this year for its global market performance in intrinsically safe cell phones and other explosion-proof devices.
The Pepperl+Fuchs Bebco EPS® 4000 series Type X purge and pressurization system, which is rated for Class I, Division 1 to non-hazardous area applications and UL, cUL, CE and EX, classified, is no longer in production. This system has been replaced by our 6000 series Type X system, an automatic purge and pressurization system that reduces the classification within an enclosure from Zone 1 and 21 to a non-hazardous area.
Its IP66-rated stainless steel casing conveniently contains the pneumatics, controller, electrical I/O, and programming interface. An easily accessible LCD screen allows easy programming and displays the pressure, flow, and system status.
The 6000 system is commonly used in applications that involve basic electronics, electrical equipment, motors, and switchgear. Bebco EPS products meet the demands of rack-mounted instrumentation, video displays, programmable controllers, computers, printers, recorders, measurement, gas analyzers, and calibration equipment.

Inductive sensors are a type of proximity sensor that use an electromagnetic field to detect metal. The oscillating electromagnetic field generated by the inductive sensor drives eddy currents through a metal target. The eddy currents in the metal target generate an opposing electromagnetic field that resists the field being generated by the sensor. This causes a power drop in the sensor, indicating the nearby metal, and an output signal is given.
Connecting a proximity sensor to a PLC can be a daunting task at first glance. For one thing, there is no universal way to connect sensors. The process varies depending on the sensor and input module used in the configuration.
On quick visual inspection, a 2-wire NAMUR sensor looks the same as a standard 2-wire DC sensor. But do not confuse the wiring connections between these two types of sensors. On the inside, NAMUR sensors have different circuitry than standard 2-wire DC sensors and need special treatment.

Is it possible to meet every requirement of an application with a single solution? It all depends on the complexity of the application. Simple applications may only need simple digital-output sensors to detect the presence or absence of a target. But what about demanding applications that involve flaw detection, high-speed target inspection, precise positioning, profile comparison, or some combination of the above?

Are unexpected issues often determining your schedule? Have you recently had to push back a project because of recurring problems? Having to respond to unplanned issues may seem like an inevitable cost of doing business, but it is becoming harder and harder to settle for a reactive approach to plant management and remain competitive at the same time.
Relying on GPS positioning inside buildings is difficult due to obstruction of the satellite signal. Bluetooth beacons are ideal for indoor positioning and have enjoyed significant market growth in recent years. As a result, Bluetooth beacons have become the industry standard for indoor navigation use and are supported by most mobile devices.
Large paper, plastic, textile, and sheet-metal rolls typically consist of multiple segments that are connected or spliced together. When the roll is unspooled and transformed into the finished product, these splices must be identified and removed. Depending on the spooled material’s properties, different sensors are required to detect the splice and stop the feed.
