Abstract
A photoelectric sensor 11 has a level display unit (28). The level display unit (28) is constituted by arranging a plurality of 7-segment indicators (33). The 7-segment indicators (33) are partially constituted of red LED segments (33b) and partially constituted of red/green two-color LED segments (33a). For a digital display, all of the segments are illuminated in red to display numerals. For a graph display, the red/green two-color LED segments are illuminated in green to present a bar graph.
Claims7
A sensor device comprising:
- feature amount acquiring means for acquiring a feature amount which represents a physical state of an object to be sensed;
- threshold setting means for setting a threshold so as to determine the feature amount;
- a display unit including a plurality of display segments arranged in an 8-shape to present a numerical display;
- and
- display mode selecting means for selecting one of a numerical display mode and a graph display mode, wherein
- at least a part of the display segments used for presenting the numerical display has a display color which can be changed,
- the feature amount or the threshold is presented by the numerical display in one display color in the numerical display mode, and
- in the graph display mode, the feature amount is displayed by a graph using display segments selected from the display segments used for presenting the numerical display, and a part of the display segments selected from the display segments used for presenting the numerical display presents a display color different from a display color of the graph in order to indicate position of the threshold in the graph by position of the part of the display segments.
