Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres. This simplifies maintenance and repair of Ex i circuits.
Pepperl+Fuchs offers a variety of intrinsic safety barriers for different requirements. Select between isolated barriers and Zener barriers that ensure safe signal transmission in hazardous areas.
Signal conditioners protect signal transfer between field devices in safe areas and control systems by galvanic isolation of the loop.
Particularly in case of long transmission paths, signal conditioners avoid compensating currents which may occur from ground loops. Signal conditioners also offer effective protection against electromagnetic disturbance or dangerous over voltages on the signal loops.
Depending on the type, signal conditioners offer additional features like limit switching, transformation from field in standard signals, as well as splitting of signals, which means doubling the input signal.

HART Interface Solutions from Pepperl+Fuchs consist of two HART Multiplexer Systems for multiple signal loops and a HART Loop Converter for single loop applications. The Multiplexer is used to connect HART field devices to Asset Management Systems like AMS™ Suite: Intelligent Device Manager from Emerson Process Management. At the heart of HART Interface Solution (HIS), the HART Multiplexer acts like a gateway device, routing communications between the maintenance workstation PC and the HART field devices. It interrogates each HART device, retrieves device information, and stores it in an internal database. This information is made available by the AMS Device Manager or PACTware. The HART Multiplexer also acts as a message coordinator for communication between the maintenance workstation PC and the HART devices. For a single loop solution, the HART Loop Converter allows access to all process variables provided by a field device and transfers them to conventional 4...20 mA loop. This enables it to make use of the hidden measurements done by many field devices and feed them to conventional DCS Systems.
In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge events can cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems—not including risks to personnel.
Besides these dangerous risks to people and environment, overvoltages are still one of the most common causes of damage in electrical plant engineering. They primarily occur due to lightning strikes or switching operations, but also due to the following causes:
Brush fire of large electric machines
Fluctuations in power supply
Ground faults / short circuits
Parallel installation of energy and information technology control systems
Pepperl+Fuchs‘ surge protection modules reliably divert surges and currents to ground and protect people and machines against possible negative consequences. Our product range provides you with powerful surge protection solutions for various applications. Find devices for signal line protection, supply line protection, fieldbus, and wireless solutions.
WirelessHART networks for process automation
Wireless communication quickly gains relevance in automation applications. For process automation, it is not the amount of data that poses challenges, but the distances to be bridged. Whenever the plant architecture does not allow conventional wiring, values are only accessible through frequent visits to the field.
WirelessHART offers a cost efficient solution. Measured values become available on a regular basis, which leads to increased quality and more economical operation of process plants.
In a WirelessHART based network, every participating device simultaneously works as a signal source and a repeater. Through the routing of the individual signals across the entire network, a wide network structure becomes possible.

The emitter and receiver on thru-beam sensors are aligned opposite one another. The advantage of this is that the light reaches the receiver directly and long detection ranges and high excess gain can therefore be achieved. These sensors are capable of reliably detecting almost any object. The angle of incidence, surface characteristics, color of the object, etc., are irrelevant and do not influence the functional reliability of the sensor.
The emitter and receiver are aligned in a housing such that the retroreflective sensors are easy to install. Simply position a reflector on the opposite side and align the sensor with it. The standard version featuring a polarization filter combines the installation benefits offered by the retroreflective system with the reliable detection, even of reflective objects, at long detection ranges. The retroreflective sensors for clear object detection are ideal for reliably detecting transparent objects.
Switching sensors with measurement core technology are based the Multi Pixel Technology (MPT) developed by Pepperl+Fuchs. Thus, multiple operating modes and switching points are easily set up in a single triangulation sensor. These photoelectric sensors can be configured as background suppression sensors, background evaluation sensors, and in window operation mode. Additionally, the sensors are equipped with a standard IO-Link interface which enables users to easily integrate them into versatile applications.
Fiber optic sensors and cables are the perfect solution for applications where the direct mounting of sensors is not possible due to space restrictions, temperature extremes, and so on. Small fiber optic beams are ideal for detecting tiny objects.
With a fast response time, the devices are ideal for detecting tiny objects from long distances. They are frequently used to detect objects on vibrating and oscillating conveyors. Slot grid sensors handle challenging counting and monitoring tasks such as detecting non-guided objects in free fall.
In the automation of packaging and printing processes, the reliable detection of print and color marks plays a key role in coordinating the various processing steps. Photoelectric contrast sensors are specially designed for such detection tasks.
Light grids are ideal for applications where wider areas need to be monitored. Light grids are much easier to mount, install, and align and are therefore preferred to multiple individual photoelectric sensors. Application areas range from controlling the width, height, and profile of pallets in material handling facilities to detecting position-independent objects, controlling overlap on larger conveyed goods, and monitoring elevator doors.
Even the smallest model is suitable for a wide range of measuring and positioning tasks. It operates using laser triangulation and an analog output. All other sensors from the VDM series use Pulse Ranging Technology, offer long sensing ranges, and achieve extremely accurate measurement results. PRT uses high-intensity light pulses to provide a high degree of operating reliability, even under difficult ambient conditions with exposure to ambient light and dust.
The optical data couplers were designed to establish wireless communication with stock feeders, industrial trucks, automated transportation systems, overhead conveyors and docking stations. Mechanical and problematic RF- and Wi-Fi-based transmissions are avoided as a result. Devices with a variety of operating ranges and transfer rates are available.
Personnel protection is becoming increasingly important in automated processes. Wherever machines perform high-risk movements, the relevant health and safety regulations must be observed. Even if the operator is momentarily distracted, shearing, crushing, and impact injuries must be prevented.

In industrial applications, ultrasonic sensors are characterized by their reliability and outstanding versatility. Ultrasonic sensors can be used to solve even the most complex tasks involving object detection or level measurement with millimetre precision, because their measuring method works reliably under almost all conditions.
No other measuring method can be successfully put to use on such a wide scale and in so many different applications. The devices are extremely robust, making them suitable for even the toughest conditions. The sensor surface cleans itself through vibration, and that is not the only reason why the sensor is insensitive to dirt. The physical principle—the propagation of sound—works, with a few exceptions, in practically any environment.
The measuring method employed by ultrasonic sensors has been viewed as an excessively complex technology, and only used as a “last resort” ... as a solution for particularly difficult applications. Those times have long since passed!
Ultrasonic sensors have proven their reliability and endurance in virtually all industrial sectors.
