PURPOSE:To detect defective mounting and to make it possible to continue measurement of material property in a furnace with emergency action being taken, by providing terminals for detecting probe confirming circuits together with measuring elements to the upward contacting terminals of the detecting probe and to the downward contacting terminals of a lance holder. CONSTITUTION:Compensating conducting wires IV and V of a component measuring element and a temperature measuring element 2 in a steel manufacturing furnace and the like and a compensating conducting wire VI which is shorted in the detecting probe (a) are gathered to an upward facing connector 21 of the probe (a). To a downward facing connector 22 of the lance holder (b), compensating conducting wires VII and VIII from the component and temperature measuring device and a compensating conducting wire IX from the detecting probe confirmation circuit are mounted. The contactable lengths of contact terminals 9 and 9' of the connector 22 for the compensating conducting wires VI and IX are shorter than those of contacting terminals 7, 7', 8, and 8' of other compensating conducting wire. When the defective connections of the connectors 21 and 22 occur, the connections are disconnected earlier than the defective connections of terminals of the measuring elements 1 and 2 and a signal is generated. Thus the measurement of the material property in the furnace can be continued with the emergency action being taken. |
