Extensive process engineering know-how is accumulated throughout the associate companies of the invensys group which is sensibly bundled in the product development: This means “Synergy at work”. A good example for this are the new process connections for pressure transmitters by FOXBORO ECKARDT which are exactly suited to the requirement profile of APV - i. e. to hygienically sensible application areas.

FOXBORO ECKARDT has vast experience in the development and production of highly accurate measuring devices. After successfully introducing the intelligent transmitters of the I/A 140 Series to the market a contact was established to the sister company APV to utilize their know-how in food processing. As result of this cooperation the elaborate process connection program for pressure and absolute pressure transmitters was expanded by five new process connections and is available immediately:

• Tri-Clamp 2”
• APV Inline Flange
• M44 x 1,25 Screwed Connection
• Milk Pipe fitting DIN 11851
• DN15/PN40 DIN Flange

Characteristic for all devices is a flush visible measuring membrane without pressure seal. This opens a wide spectrum of applications for the pressure transmitters exactly in those areas in which APV is strong: in the food and pharmaceutical industries, in the beverage and brewery industries and in other areas of chemical engineering. Since these are hygienically sensible areas it goes without saying that the flush measuring membrane does not show any rough edges nor any dead space: This is an important basis for the certification of applications in food process engineering.

As process contacted material solely stainless steel 316L (1.4435 / 1.4404) is used. All connection between measuring membrane and the respective process connection are welded so that even the most severe hygienic requirements are fulfilled. The robust and safe two-chamber amplifier housing is also available in stainless steel.

Requirements demanded by CIP and SIP processes for a modern, reliable measuring device, naturally, are also being fulfilled.

That the new process connections were especially designed for food processing, is evident from the fact that FOXBORO ECKARDT has subjected the three versions with Tri Clamp2”, M44 x 1,25 and APV Inline connection to the discriminating tests according to EHEDG (European Hygienic Equipment Design Group) criteria in order to receive a respective certificate from the Lehrstuhl für Maschinen- und Apparatekunde Weihenstephan . 3A Certification will be applied for shortly.

The transmitters are available in the electrical classification EEx ia IICT4, fulfilling the requirements of protection type IP66. The intelligent electronics permit communication in the HART standard; additionally, the communication protocol FOXCOM enables the complete digital integration of the transmitters into the FOXBORO I/A Series System. The mechanical assembly technique developed by FOXBORO ECKARDT enables the easier implementation of the flush measuring tools in almost all process connections.
