Process Automation for the Primary Industries

Measuring technology, services and systems for process automation

The results of a market survey in diverse industry segments within the primary industries showed the unequivocal trend toward qualified and certified companies and the underlying will to reduce the number of suppliers. 137 of the 250 surveyed companies saw the complete range supplier for the automation technology as important or even very important. Endress+Hauser supplies sensors, measuring instruments, systems and services for pressure, flow, level and temperature measurement and liquid analysis, data acquisition of the measured values as well as samplers, system components and automated solutions.

New trends in pressure measuring technology

(Fig. 1)

Classical applications for pressure technology are found today in the bulk material industry and its abrasive environments.

Endress+Hauser introduced the new pressure and differential pressure transmitter Cerabar S / Deltabar S at the PowTech in Nuremberg, Germany. Cerabar S / Deltabar S is a unit which ensures reliable operation of processes and which supplies important process data.

Technical features:

- Quick set-up for fast and simple configuration

- Adjustable measuring range requiring no pressure

- Optimising processes while using for the first time a pressure device with a metal diaphragm without diaphragm seal (up to 280 °C)

- Measured accuracy: 0.075 %

Remote monitoring of field instruments per INTERNET

(Fig. 2)

Modern INTERNET technology, together with Endress+Hauser Fieldgate, enables remote access to measured values, remote configuration and diagnosis of instrumentation. Employing this concept, data and information regarding the status of field instrumentation can be obtained any time and any place.

Communication is by standardised media such as mobile phone, telephone or ETHERNET. In addition, storage and supply processes can be optimised. The connection of field instrumentation with remote data scanning is through all 4 ... 20mA, HART® or PROFIBUS PA signals with Web-Browser. Available software standards (e.g. MS-EXCEL®, SCADA Software) can be used. The supported data transfer in XML format allows for easy evaluation and processing of measured data.

Life Cycle Management around the measuring instruments

Calibration: 250 companies from the bulk material handling industry said in a market study that nearly 60% of their field instrumentation had to be calibrated regularly. Endress+Hauser has five of its own accredited test laboratories for calibration and also supplies field calibration directly on site.

Within the framework of the DIN EN ISO 9001 Rev. 2000/chapter 7.6 qualification, the cyclical test and calibration of measurement and test materials is required so that the accuracy within the listed tolerances can be maintained and proven.

ATEX-Guideline: In the market study listed above, 46% of the people questioned said that explosion protection is a serious topic in their process plants. 60 % said that they are informed regarding the new regulation with the EU ATEX guidelines (for user relevant guideline 1999/92/E^^G). The transition period ended on July 1st2003. Endress+Hauser supplies, next to the certificates for the gas explosion endangered area, a package from the diverse fields of activity (level, pressure, flow, system components , temperature etc.), devices for use in dust explosion endangered parts.
