Beschreibung
Zusammenfassung:	A sensor for detection and measurement of incompatible (corrosive or foreign) materials in a fluid medium. The sensor includes a tuning fork mounted on a diaphragm with tines having an amplitude and a resonant frequency. The sensor alarms when a measured amount of the incompatible material has been deposited on the sensor to form a fusing element on the tines which causes vibration of the tines to cease.
