METHOD AND DEVICE FOR MONITORING SEPARATION OF LIQUID JET

摘要

PROBLEM TO BE SOLVED: To automatically monitor the separation of a liquid jet which is produced in a cell selecting device, for example. SOLUTION: Image of separation in a liquid jet FL is recorded, and the position of the separation point where liquid drops each are separated from the liquid jet is found by the image analyzing method. The arrangement includes a detection means VID to sense the position where the separation point changes, an evaluating means PC to evaluate the detected position of the separation point by comparing the delected position with at least one positional limit value, and an operating means which stops the process and issues an alarm when the obtained position exceeds a limit value or gets under the limit value.
