Simple connectivity with the Rotronic Monitoring System (RMS)

Introduction:

Reducing costs and improving quality are key drivers for any business. RMS applications typically target these aspects of our customers operations and a recent project with here in the UK was no exception.

Following an initial enquiry it was clear that a custom selection of RMS hardware and setup would be required, however this was no reason not to proceed with a bespoke solution.

Customer Process:

The project was based around a wider roll out of a new technology in the manufacturing process of our customer. The process required the use of special epoxy adhesives that themselves require very strict ambient and surface temperature conditions. Outside these conditions the bonding process would not be adequate. As such monitoring was critical to ensure and prove conditions were being met during production.

Some Chemistry:

Epoxy resins a reactive pre-polymers, they have the potential to react and cross link. It is this cross linking that when triggered turns a stable liquid into a thermo-setting polymer. The set polymer typically has extremely high thermal and chemical resistance. Epoxy resins are commonly used as adhesives and coatings in many industries such as carbon fibre and ship building.

What are the monitoring requirements

Ambient conditions and surface temperatures are critical for the client procedure.  The production area was therefore independently controlled by a specific HVAC system. Previous manual checks lacked quantitative detail and were costly to implement

The Solution – RMS Continuous Monitoring

RMS provided the perfect solution. Using an RMS-LOG-868 high accuracy humidity and temperature loggers combined with an economical RMS-MLOG mini-loggers all measurements could be made in real time. A custom magnetic surface temperature probe was utilised so the customer could accurately measure the surface temperature as per their quality requirements. Live ambient dew point was calculated via RMS and then this value was compared with surface temperature using a simple arithmetic calculation. Thus a live trace of surface temperature vs dew point temperature was provided giving a clear indication whether there would be a risk of surface condensation. Parameters were configured with warning and alarm limits linked to emails, SMS and telephone alerts as well as clear visual displays via tablets and PCs.

As such the customer could be confident that should conditions not be favourable they would know, in addition for QA a full record of all conditions was easily available with automated reporting and full audit trail.

Simplifying Connectivity

Cconnectivity was an issue on such a large site. No network access was available at all. A 4G solution resolved these and provided data direct connectivity at all times through out the site.

Fully mobile kit was created requiring only a mains power supply for operation. Wireless loggers could then be moved and placed as required always in range of the 4G communications kit.

Even if connectivity or power was lost for any reason, all the wireless loggers would continue logging on their 3 year batteries and maintain a 1 month record that automatically synchronised back to the RMS software once 4G connection was restored.

The entire system was setup and configured exactly as required from the Rotronic office, including device pairing and software configuration allowing the client to log on from their offices and make comments and changes. A subsequent visit to site met with no technical issues or surprises. This also kept service costs to a minimum for an initial proof of concept project.

4G connectivity reducing need for on-site infrastructure and IT issues.

This is just one example of an RMS implementation. With a range of cloud and on premises software along with wireless and wired devices if you have a monitoring application we are confident we can find a solution to meet your needs and budget.

Ladies Only Exhibition in Perfect Monitored Climate

The Hohenzollern family came to Brandenburg 600 years ago, in 1415. Twelve prince-electors, seven kings and three emperors made Prussian, German and European history for almost 500 years.

The women have been some what overlooked by historians, by turning the spotlight on them, the foundation for Prussian castles and gardens has paved the way to discovering hitherto unknown aspects of Prussian and European history. The foundation presents 300 exhibits from national and international donors in a an area of 900 Square meters, which include the oldest authentic woman’s dress in Brandenburg (c.1460) and the coronation cloak of Queen Augusta. 

The painting is that of Queen Augusta of Prussia, which is exhibited in a perfectly climatised room

Room Climate in exhibitions 

The climate and lighting are the most influential factors to ensure the preservation of museum exhibits, because they can cause damage by accelerating chemical and biological degradation processes. In recent decades, the exhibition sector has developed a standard for conservation conditions in exhibitions. For those with the most varied works of art, temperatures of 18°c-22°c and relative humidity around 50 %RH with slight variations, and lighting of 50 to 200 Lux, are striven for, depending on the sensitivity of the materials.

Theater “Ladies Only”

The theater in Charlottenburg has no central air conditioning system. The room climate is influenced by a massive building shell, with masonry walls some as thick as 80cm, solid, reinforced concrete ceilings and floors, and composite windows with double glazing. To reduce warming through sunlight, the windows on the south side have been given sunshades for the duration of the exhibition.

Measuring Equipment 

The foundation has until now had no experience with using the building as an exhibition area. For this reason there were very high demands on the quality and availability of the measurement data. The concept for the exhibition combines a large number of works of art made of the most varied and sensitive materials, understanding of measurements is developed over days, months and years.

“The Rotronic measuring system was convincing because of its high degree of data  security, but also because of its flexibility, low maintenance costs and simple operation.” Wulf Eckermann – Stiftung Preussische Schlosser, Germany

Rotronic Data Loggers

Suitable for a wide range of humidity and temperature monitoring tasks, Wireless transmission – Possible over distances of up to 100m.

log-hc2-rc_mit_clip_3Saves on wiring costs, and the data can be collected and recorded from inaccessible points quickly and easily. Thanks to the combination of wireless transmission and data logger, the greatest possible reliability against failure is ensured. Devices can be configured and read out via the HW4 software and now our latest web or server enabled RMS software. Application uses include: Meteorology, Food Industry, Building Technology, Museums, Environmental/Laboratory equipment, research an development, Pharmaceutical/chemical/logistics and textile industry.

Wireless data loggers for active monitoring

To monitor the climatic conditions reliably and flexibly, HL-RC-B wireless data loggers are used. The measured values are recorded locally and safe from manipulation in a memory with a capacity of 500,000 values. With no cabling requirement, and without provision of an infrastructure such as a LAN or power outlets, the loggers are mounted unobtrusively on walls and in glass cases, thus impinging only minimally on the exhibition concept.
