    • The present invention is a substance displacement device. The device includes a sensing unit which is positioned in a drill hole or otherwise within the substance, such as soil or rock. A measurement device is connected to the sensing unit to measure changes in resistance caused by deformation of the sensing device. A control device connected to the measuring device determines whether the change in resistance exceeds a threshold, and thus activates an alarm. The sensing device preferably includes a fixed resistance device across its terminations to enable the establishing of a baseline resistance. The sensing device may include an electrical element or an optical element. The alarm can be any suitable type of alarm.
    • 本发明是物质置换装置。 该装置包括位于钻孔中或其他物质内的感测单元,例如土壤或岩石。 测量装置连接到感测单元以测量由感测装置的变形引起的电阻变化。 连接到测量装置的控制装置确定电阻的变化是否超过阈值,从而激活报警。 感测装置优选地包括跨越其终端的固定电阻装置,以使得能够建立基线电阻。 感测装置可以包括电元件或光学元件。 报警器可以是任何合适的报警类型。
