摘要：The temperature and/or moisture profile over time of gypsum boards is

monitored as the boards harden, to facilitate effective curing of the boards prior to

removing excess water therein in an industrial dryer. A substrate is moved by a curing

conveyor beneath a gypsum slurry mixer, and the mixer pours slurry onto the substrate.

Just prior to the substrate passing under the mixer, an operator places a monitor onto

the substrate. The monitor can include a temperature sensor, a conductivity sensor, and a

microprocessor that receives and stores the signals from the sensors. The monitor is

configured such that the height of the sensor or sensors is equal to one-half the height

of the hardening boards. The slurry that has poured onto the monitor hardens into a test

board, and when the test board arrives at the end of the curing conveyor, an operator

breaks open the test board, removes the monitor, and connects the microprocessor in

the monitor to a computer via a serial port cable. The computer outputs temperature

and moisture profiles as sensed by the temperature and conductivity sensors, with the

profiles being representative of the efficacy of the curing of the boards in the particular

batch of boards that were poured with the test board.
