Title:
IDENTIFYING DEVICE FOR ROTORS OF CENTRIFUGE
Document Type and Number:
Japanese Patent JP3780670
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an identifying device of high reliability and stability for surely detecting an identifier to eliminate identifying errors to the utmost with respect to identifying devices for rotors of a centrifuge for identifying various kinds of plural rotors mounted on a crown or the like of a centrifuge.
SOLUTION: There are provided a sensor head 4 for detecting an identifier 3, an oscillation circuit 5 for oscillating in cooperation with the sensor head 4, a frequency voltage converter 6 for converting oscillation frequency of the oscillation circuit 5 into voltage, an identifier detection means 7 for detecting the identifier 3 from an output signal of the frequency voltage converter 6, a means 8 for measuring the oscillation frequency of the oscillation circuit 5, and a means 9 for controlling the frequency of the oscillation circuit 5. By the means 8 for measuring oscillation frequency, the oscillation frequency of the oscillation circuit is measured immediately before rotor identification action start, and by the means 9 for controlling the oscillation frequency of the oscillation circuit 5, the oscillation frequency of the oscillation circuit 6 is set at the prescribed frequency previously specified.
