Abstract

Σε μίαν μέθοδο μέτρησης της πυκνότητας μίας ουσίας όπως γλυκόζης σε ένα δείγμα υγρού όπως αίματος ή διάμεσου υγρού, παρέχεται μία συσκευή μέτρησης έχουσα ένα τμήμα αισθητήρα εργασίας (6b), ένα δεύτερο τμήμα αισθητήρα εργασίας (8b) και ένα τμήμα αισθητήρα αναφοράς (4b). Το δείγμα υγρού τοποθετείται στην συσκευή μέτρησης και ένα ηλεκτρικό ρεύμα ανάλογο προς την πυκνότητα της ουσίας στο δείγμα υγρού μετράται σε έκαστο τμήμα αισθητήρα (6b, 8b). Τα ηλεκτρικά ρεύματα συγκρίνονται προς εξακρίβωση της διαφοράς. Εάν η διαφορά είναι μεγαλύτερη από ένα προκαθορισμένο κατώφλιο, δίδεται μία ένδειξη σφάλματος. Μία ταινία δοκιμής μίας χρήσεως με δύο αισθητήρες εργασίας (6b, 8b) επίσης αποκαλύπτεται.
