Easily Protect against Surge Voltage

The new M-LB-2000 system offers surge protection with nothing more than a loop disconnect function for easy maintenance and commissioning, making it ideal for use in applications that only require a minimal specification.

The M-LB-2000 can also be used as a superior alternative to terminal blocks with surge protection. The terminal blocks can be replaced by the 6.2 mm slim modules with no additional space required. The one-piece devices can be mounted on a standard DIN mounting rail, are approved for applications up to SIL 3, and are certified in accordance with Atex and IECEx up to Zone 1. This makes the M-LB-2000 system the ideal complement to the M-LB-5000 surge protection system – the two-part system that offers diagnostic functions.

The M-LB-5000 with condition monitoring function has patented diagnostics and uses a special algorithm to detect different overload situations that can cause the surge protection functionality to wear out. This improves the availability of the protective function, and therefore the system as a whole, while minimizing maintenance costs. The traffic-light display on each protection module greatly reduces testing work, as the fault can very easily be assigned to a specific signal circuit.

This system also offers considerable advantages over other solutions when it comes to maintenance. For example, the base module on the DIN mounting rail stops the signal from being interrupted when the protection module is disconnected. A protection module can therefore be replaced without affecting plant operation. However, if the signal circuit needs to be intentionally interrupted – for isolation tests during commissioning, for example – the protection module can simply be rotated by 180 degrees and plugged in. In this case, the signal circuit is interrupted by an integrated isolating function.

The number of patents submitted by the Endress+Hauser Group continues to rise. As reported during the annual Innovators’ Meeting held this year in France, the Group submitted 287 initial patents in 2018, a new record. Endress+Hauser owns nearly 7,800 active intellectual property rights worldwide.

“This year we once again achieved a record number of innovations, both in the number of patent filings and the number of approved patents.”

Angelika Andres, Corporate Director, Intellectual Property Rights at Endress+Hauser

While the 309 invention disclosures are a sign of the company’s ongoing innovation capability, the 537 granted patent applications also represent an all-time high.

Roughly one-third of the patent filings are related to the Industrial Internet of Things, digital communications and instrument diagnostics. Under the motto #empowerthefield, in 2018 the measurement engineering specialist began to bundle its digital activities with a focus on Heartbeat Technology, as well as the recently introduced Netilion IIoT ecosystem.

Patent department in the US

Each invention undergoes a multistage internal evaluation process before submission to the patent office, usually within four months. To handle the stream of innovations, in 2016 an internal patent department was created in the US, one of the Group’s most important markets. Four specialists at the Greenwood, Indiana location are responsible for protecting the technical innovations. This team has full responsibility for handling all patent filings from the Group companies located in the US, plus up to 80 percent of the overseas filings.

Innovation spirit in the spotlight

Under the motto ‘Innovation – what makes us human’, Matthias Altendorf, CEO of the Endress+Hauser Group, as well as other members of the Executive Board, welcomed more than 300 guests to the annual Innovators’ Meeting, which was held in late March in Saint-Louis, France. Employees involved in patent filings presented their innovations during the company’s traditional get-together. Exceptional innovations were recognized with special awards.

The S8000 Chilled Mirror Hygrometer Range Michell

In many processes moisture is a critical factor that needs to be monitored, and controlled. Chilled mirror is the technology of choice for humidity measurements to national standards in laboratories worldwide.

Chilled mirror has the highest attainable accuracy of any dew-point measurement technology, and provides excellent repeatability over a wide measurement range. It is a proven, well established and reliable measurement technique: the temperature at which condensation forms on a surface is measured directly, so there are no calculated variables that could change over time. This means chilled mirror does not suffer from drift or hysteresis.

Enabling Security

Analog Devices Enabling Security in the Totally-Connected world of Industry 4.0

Analog Devices (ADI) will once again have a noteworthy presence at the Hannover Messe, with demonstrations and speaking engagements focussing on the key issues of concern to visitors to this premier event for all aspects of industrial and automation technology.

ADI, on stand H23 in hall 9 of the exhibition, will show how its unique position at the intersection of analog and digital technologies, and in both the hardware and software of computing solutions, equip it to offer solutions in areas such as machine learning and machine monitoring, comprehensive connectivity – with security – and in the industrial maintenance domains with artificial intelligence.

A featured demonstration will illustrate a comprehensive approach to machine and structural health monitoring, showing how ADI’s best-in-class MEMS technologies provide precision sensing, while the company’s mastery of high-performance analog-to-digital and power conversion delivers ultra-low-power signal processing. “Deep signal chain”, and system design, insights enable customers to extract greater value from their systems, with improved user experiences. Real-time, 24-hour monitoring will be shown in both dynamic (motor) and structural (equipment mounting) contexts, comprising a methodology for complete supervision of an equipment installation.

At the heart of these topics are technologies such as complete, factory- and enterprise-wide connectivity and all that goes with it, a particular concern in 2019 being cyber security. ADI will address the issue as part of a demonstration highlighting the range of solutions that the company can offer to advance Industry 4.0.  Enhanced cyber security within the factory control loop, at the edge of industrial networks will be highlighted as part of an illustration of Time Sensitive Networking (TSN) techniques, boosting security alongside features such as time synchronization, pre-emption and control of TSN via OPC-UA.

Analog Devices’ staff will be on hand to answer visitors’ questions on any of the focus areas for Hannover Messe 2019 – connectivity, cyber security, machine monitoring and maintenance – or on any aspect of the company’s technology and product offering.

Extending the secure edge in industrial control

For many visitors to Hannover Messe the need to consider security is a new, and worrying, addition to their workload. Any IT system is only as secure as its weakest link. Industry 4.0 means that the network extends to every sensor and actuator; potential points of attack exist everywhere from the edge to the core. Security-by-isolation and reliance on monitoring network traffic are no longer adequate, leading to the need to establish device level security at the edge.

Recognising these concerns, and to assist visitors seeking solutions, ADI will present a paper in the conference strand of Hannover Messe, focussing on the “hot topic” of security in the industrial context. To be delivered by Erik Halthen, System Security Manager at ADI, the paper will develop the theme that enabling a new industrial revolution of real time, autonomous decisions requires increased connectivity and edge computing that fundamentally changes the required approach to cyber security.
