A fusion of modern technology with classic functionality Pressure gauges with a moving needle may conjure up thoughts of old-fashioned engineering, but maybe there's a place for such things yet. Add a modern sensing element and some state-of-the art electronics, and there you have it: the new PG Manometer range from sensor market leader ifm electronic. One device instead of two – no longer does the user need to have a separate pressure gauge and a pressure switch, because of course the PG Manometer from ifm electronic is more than just a visual indicator, though it does that with a digital LED display as well as the pointer. It is also a versatile pressure sensor, with an output capable of switching 250 mA, selectable normally open or normally closed and able to automatically detect PNP or NPN. Not only that, but the second output is a scalable analogue current signal. Modern electronics allow the face of the gauge to show illuminated set and reset points, or the pressure as an illuminated ring, as well as a moving needle. The electronics in the setting permit a host of variations to be selected. These range, amongst others, from hysteresis or window function selection, damping, display unit choice to electronic locking of the settings. Mounting position need not pose any problems, as the display can be rotated through 350 degrees. Versions so far available cover eight different ranges of relative pressure, starting at –1bar and extending up to 25bar. The medium can be liquid or gaseous. Food and pharmaceutical applications suggest themselves as ideal for the PG manometer, as the materials used are ideal for those industries, as are the hygienic process connections and seals on offer. Materials in contact with the medium are only high-grade stainless steel, ceramic and PTFE. In summary, the PG manometer can offer higher accuracy than mechanical manometer, with excellent overload protection as well as very high vibration and shock resistance. The electronic manometer is three units in one: analogue display, transducer and switch. Unlike a mechanical device, the manometer has many more functions, with parameters that can easily be set. The sensor technology using the 99.9 % purity ceramics is well proven, making the unit wear-free and maintenance-free. For further information on PG Electronic Pressure Sensor
