Title: Apparatus for detecting corrosion of wall of refractory material
Inventor: MORIYAMA TAKASHI
IPC: F27D21/00
Filed: 1987-08-10
Abstract: PURPOSE:To implement a self-holding circuit of detected signals from a plurality of sensors for detecting corrosion in the wall of a refractory material, by combining two-input OR circuits and nonvolatile memory. CONSTITUTION:When the corrosion of the wall of a refractory material progresses, the contact points in sensors S1-Sn for detecting the corrosion of the wall of the refractory material are fused, and the detected signal is obtained at every contact point. The detected signals are inputted into two-input OR circuits 5-1-5-n. The output signals from the circuits are stored in a nonvolatile memory 6. Display parts 8-1-8-n receive the data signals, which are read out of the memory 6. The display parts are operated. The state of the corrosion of the wall of the refractory material is displayed. Meanwhile, when the contact points are short-circuited during the measurement and the detected signals from the sensor are fluctuated, the retrieved data signal, which is the same as the detected signal before the fluctuation, is continuously stored in the memory 6 by obtaining the OR value with the detected signal, because the data signal that is read out of the memory 6 is inputted into the two-input OR circuit. Thus, the detected signal with regard to the corrosion of the wall of the refractory material, which has once obtained, is maintained by a self-holding operation.
