Title:
火炎センサの状態表示装置
Document Type and Number:
Japanese Patent JP7398802
Kind Code:
B2
Abstract:
To provide a status display device for a flame sensor that easily enables visual recognition of a status of a flame sensor without using a measuring instrument or the like by stepwisely setting multiple threshold values with respect to the output values of the flame sensor, and lighting and displaying an LED or the like in a lighting pattern according to the threshold value which the output value of the flame sensor exceeds.SOLUTION: A status display device for a flame sensor is provided with: a flame sensor 10 that detects a flame of a combustion device 2 and outputs an output voltage correlated with an ignition status; and an LED 18 that stepwisely sets at least two threshold values with respect to an output voltage VS from the flame sensor 10 and displays by lighting and blinking according to the exceeded threshold value when the output voltage VS exceeds the set threshold value.SELECTED DRAWING: Figure 2
