    • An indicator for displaying measurement and surface deviation from initial reference measurement level which includes the probe needle (N) positionable against the surface being measured. The probe needle (N) provides a control signal representative of probe needle (N) position and there is provided display (Y) for displaying the relative surface deviation from the reference measurement level. The sensor from the probe needle (N) comprises a capacitive sensing layers comprising a fixed plate (22A) and a movable plate (22) with the probe needle (N) secured to the movable plate (22) whereby the movable plate moves with the probe needle (N) to cause a change in capacitance between the plates thereby generating the control signal.
    • 用于显示与初始参考测量水平的测量和表面偏差的指示器,其包括可针对被测量表面定位的探针(N)。 探针(N)提供代表探针(N)位置的控制信号,并且提供用于显示与参考测量水平的相对表面偏差的显示(Y)。 来自探针(N)的传感器包括电容感测层,其包括固定板(22A)和可动板(22),探针(N)固定在可动板(22)上,由此可移动板随 探针(N)引起板之间的电容变化,从而产生控制信号。
