Instrumentation and control manufacturer relies on advice
From product to solution provider

Consulting is a central element of the Jumo Engineering concept. The Fulda based group has combined its engineering services under this name and is hence optimally placed to offer bespoke, end-to-end solutions for complex automation tasks. Jumo now additionally supports its customers with specialised product management for SIL and functional safety.

Technology is getting more and more complicated – there’s no denying the truth of this often-voiced complaint. A growing number of plants and processes are nowadays controlled and monitored completely automatically. As Industry 4.0 gains ground, this trend is almost certain to increase. Revenue in the German automation industry has risen by more than 70 % since 2002, and with a global market share of around 10 % Germany ranks number four in the list of the most important manufacturing countries when it comes to automation.
As the machinery and plant becomes more complex, so do the demands made by users. They are no longer looking for individual sensors or controllers but want a comprehensive solution for their problems. This is why the focus is no longer on individual products but rather on the optimal interaction of all the components used.
Several years ago now, Jumo took the first important step from being a supplier of components to a system provider with the introduction of the modular Jumo mTron T measuring, control and automation system. In the period that followed, it turned out that consulting services were also being provided for many of the systems implemented. The next logical move, therefore, was to bundle the available skills together under the heading Jumo Engineering and make them accessible for other Jumo products.
The Engineering team, whose members have many years of automation experience, develops tailored applications for numerous industries such as food and beverages, water and wastewater engineering, pharmaceutical manufacturing, heating and air conditioning, chemicals and the rapidly expanding renewable energy sector.
The team’s portfolio is extensive, ranging from basic feasibility studies and workshops to detailed specifications and end-to-end project management. They boast considerable experience in PLC programming, visualisation and network technology.
Customer applications are developed and created based on Jumo products. This is because Jumo’s product range already covers the entire solution chain from sensor technology for temperature, pressure, liquid analysis and flow to compatible devices for recording, controlling and automation. The spectrum also includes all the necessary actuators such as solid state relays (SSR) and SCR power controllers. This results in efficient solutions which are optimally aligned to each other – all from one service provider.
These applications are commissioned on site. Customers receive comprehensive product documentation and a bespoke operating man-ual. Support and other services as well as specific training round off the package. Clients can choose between individual components or an entire project. Jumo Engineering operates both nationally and internationally.
Systematic approach to minimising risk
Besides increased automation, SIL and functional safety have for a long time been crucial topics in specialist media as well as at conferences and trade fairs. Although much has been written and spoken about them, they generally remain clouded in mystery. Even though SIL is easily defined as a measuring unit to quantify risk reduction, implementing it in concrete processes is often a great challenge.
The vast number of underlying standards alone means users require detailed expert knowledge, which is why Jumo supports its customers with specialised market segment management. Various innovative solutions are offered in connection with functional safety.
In a typical process, sensors measure variables such as temperature, level or pressure and convert the measured values into standard signals. The evaluation electronics normally encompass control units that convert, linearise, save and process the variables according to a set of rules and send them to the actuator for execution. The actuators then perform operations on the process by adjusting a wide range of functional variables.
Two approaches exist for implementing safety variants in evaluation electronics. The first is to use a programmable safety logic controller. This solution is particularly well-suited for building special systems with a process control system and is characterised by comprehensive functional applications as well as a higher density and number of signals. However, it also requires more extensive programming applications and the inputs and outputs are coupled with card types and multichannel features. The investment costs vary depending on the number of channels and the software complexity. In addition, each application must be separately calculated and evaluated according to the SIL. Solutions up to SIL 4 can be realised.
Safety monitors and limiters such as the Jumo SafetyM represent a good alternative to programmable safety logic controllers. This instrument is ideal for smaller functional applications like special-purpose machines or one-off scenarios with a low density and a small number of signals. In addition to minimal investment costs, the advantages here include simpler parameterising for each application or control function.
The solution operates with universal input signals and features a redundant internal structure with redundant sensor inputs. Three different functional outputs are also available (analogue/binary) for solutions up to SI L 3 or PLe. What’s more, the entire SIL chain is already calculated in conjunction with defined Jumo sensor technology. Of course, sensors from other manufacturers can be easily connected and users are not limited to a specific supplier – even though the use of products from one manufacturer has its benefits.
