Highly precise printing transducer

With the pressure absorber AccuSenseTM model ASM is used a new, digital measuring procedure consisting of capacitive and inductive sensor elements. LC used the resonant frequency one as sensor element � resonant circuit by change of capacity proportionally to the introductory pressure is changed here and to a counter supplied. This determined over a constant gate time a digital illustration dominant this procedure reaches an accuracy of � 0.05% of the measuring range. Are available measuring range from 1 bar to 70 bar for absolute, relative and positive pressure measurements, a vacuum range up to -1 bar round the application possibilities of this transducer off. Different output signals of 0 � 5 V, 0 � 10 V or 4 � 20 mA permit a problem-free subsequent treatment of the exit according to the already existing instrumenting. Also regarding the supply the AccuSenseTM is very flexible: it can be operated at DC voltages within the range of 9 � 30 V. By the digital compensation of the temperature influences a total accuracy of 0,25% v. becomes final value in the temperature range of -20 �. + 60�C obtains. With different process connections, as well as optional plug or cable connection, this printing transducer for fastidious laboratory, attempt and applications of test stands is suitable exactly the same as for industrial applications.
