A multiple temperature sensor system (120) includes a temperature sensor network (180) including temperature-sensing resistors R T1 and R T2 (186, 187) and frequency-selective filters (184, 185) coupled to the plurality of temperature-sensing resistors R T1 and R T2 (186, 187). The frequency-selective filters (184, 185) pass distinct time-varying signals into the temperature sensor network (180) and pass attenuated distinct time-varying signals out. The system (120) further includes a temperature measurement controller (161) coupled to the temperature sensor network (180) and configured to inject the distinct time-varying signals into the temperature sensor network (180), receive the attenuated distinct time-varying signals in response to the injection, with the attenuated distinct time-varying signals being attenuated by the temperature sensing resistors (186, 187), and generate two or more substantially simultaneous temperature values from the attenuated distinct time-varying signals.

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.

An environmental information measurement device includes: a power source unit; an environmental information detector; a timer; and a controller. The power source unit generates, from an electromagnetic wave received, a power source voltage to be supplied to a load. The load includes the environmental information detector, the timer, and the controller. The environmental information detector includes a detector including a circuit element having an impedance or an electrostatic capacitance that varies according to a physical amount detected under an environment at a measurement target point, and outputs a signal that varies according to a response characteristic of the detector. The timer measures a duration from the time when measurement is initiated to the time when a voltage of the signal becomes a predetermined detection voltage. The controller controls an operation of the environmental information detector.
