  • Sensing mat, and methods of constructing and utilizing same
    Patent number: 5192932
    Abstract: A device for sensing the presence of liquids or other substances and warning of potential hazards. The device includes a mat which is constructed of metalized sheets. This mat may be cut to any size or shape on site. A monitoring device is electrically connected to the mat and monitors a change in capacitance or resistance of the mat. Such a change is an indication of the presence of unwanted substance. The monitoring device may then either activate an alarm or turn off any electrical devices as deemed necessary. The mat can include a sensitivity layer which may be included to require a greater amount of liquid or other substances to trip the monitoring device. The control module preferably operates on a large range of power voltages, preferably the same as the equipment being monitored.
