Profile calibrator sucks water, not air.An innovative calibrator calibrator an instrument for dilating a tubular structure or for determining the caliber of such a structure. reduces both the initial price and operating cost of a typical vacuum calibrator. Instead of the usual solid block of steel bored out with channels for cooling water and vacuum, Technoplast Kunststofftechnik GmbH in Austria uses a 3- to 5-mm micro-perforated steel plate backed with water at less than atmospheric pressure atmospheric pressure or barometric pressure Force per unit area exerted by the air above the surface of the Earth. Standard sea-level pressure, by definition, equals 1 atmosphere (atm), or 29.92 in. (760 mm) of mercury, 14.70 lbs per square in., or 101. , drawn by a suction suction /suc·tion/ (suk´shun) aspiration of gas or fluid by mechanical means. post-tussive suction a sucking sound heard over a lung cavity just after a cough. pump. Thus, cooling water inside the calibrator is pulled past the profile and through the microholes, holding the profile against the calibrator much the way a vacuum calibrator typically does. Energy use for the water-suction pump, however, is only 2.2 kw vs. 4.5 to 5.5 kw for three to five vacuum pumps on a typical calibrator. Technoplast, whose U.S. office recently moved to Cranberry cranberry, low creeping evergreen bog plant of the genus Oxycoccus of the family Ericaceae (heath family). Cranberries are considered by some botanists to belong to the blueberry genus Vaccinium. , Pa., has sold 10 of these water-suction profile calibrators in Europe.
