WIRELESS ROD

摘要

FIELD: measurement equipment.SUBSTANCE: invention relates to a measurement system of molten metal properties. The system includes a contact block made so that it can be functionally connected to the first end of a hollow rod holder. The contact block is connected in a detachable manner and electrically to a measurement sensor and receives analogue signals from it. The contact block converts received analogue signals to ultrasonic signals and transmits ultrasonic signals through a cavity of the rod holder. The receiving unit is made so that it can be functionally connected to the second end of the rod holder. The second end of the rod holder is opposite to the first end. The receiving unit receives ultrasonic signals from the contact block and converts the received ultrasonic signals to a digital voltage signal.EFFECT: use of the invention provides safety of the system and minimises costs for its repair.20 cl, 9 dwg
