IMAGINE you're buying a new BMW. Would you really use all the features in that deluxe 7-series model?
You may find all the capacity and functionality you need in a middle-range 5-series model - or in an even more compact and simple 3-series model - at considerably lower cost, yet with no less quality, reliability and after-sales back-up.
Process automation company Endress+Hauser has adopted a similar 3/5/7 market segmentation philosophy, designated the Cerabar S/M/T strategy.
Its high-quality Cerabar pressure transmitters, for example, accurately and reliably measure pressures of liquids, vapours and gases in safe and hazardous areas. At the same time, each segment within the Cerabar range offers distinctly different functionality, applicability and cost.
Simple, low-priced Cerabar T is a fixed-range pressure transducer. What is unique is that the Cerabar T is available with the robust, chemical-resistant ceramic measuring cell up to 40 bar ABS, or gauge, and 400 bar with the polysilicon cell.
The new PMC135 is also available with integrated Tri-clamp/SMS process connection for hygienic applications.
Medium-priced Cerabar M is a multi-purpose pressure transmitter, ideal for the food and pharmaceutical industries (with stainless steel housing) and chemical applications (with powder-coated aluminium housings).
Compared with Cerabar T it offers ±0.2% linearity (versus ±0.5%), programmability and compatibility with HART and Profibus PA.
The top-of-the-range Cerabar S pressure transmitter has universal application and provides maximum linearity and versatility.
It features high turndown, ceramic and polysilicon measuring cells, a 'watchdog' facility to record incidents of over-pressure and over-temperature, stainless-steel housing, an extensive range of process connections and an additional Foundation Fieldbus option.
“Sometimes top-of-the-range technical solutions represent the best investment, and sometimes they don't,” says John Immelman, managing director of Endress+Hauser Australia.
“The S/M/T approach helps us provide exactly the level of functionality each customer needs for each application, so they don't invest capital in superfluous features.”
