WIRELESS LANCE

摘要

A system for wirelessly obtaining a measurement of a characteristic of a molten metal is disclosed. The system includes a contact block configured to be operatively coupled to a first end of a substantially hollow lance holder. The contact block is detachably and electrically coupled to and receives analog signals from a measurement sensor. The contact block converts the received analog signals into ultrasonic signals and transmits the ultrasonic signals through the hollow of the lance holder. A receiver block is configured to be operatively coupled to a second end of the lance holder. The second end is opposite the first end of the lance holder. The receiver block receives the ultrasonic signals from the contact block and converts the received ultrasonic signals into a digital voltage signal.
