Depending on where the workpiece is being measured, some probes with small radii may be bounded between or on top of the surface high point and the irregular shape. Large or flat probes will be supported by high points, and the choice of probe radius depends on whether you want to ignore irregular surfaces above or below.
Because all materials will be deformed to varying degrees when in contact with them, the shape of the contact and the size of the deformation will also affect the measurement effect, and there are simple and standard industry-accepted measurement methods for measuring the thickness of insulated wires, rubber sheets and other materials.
You have to think about durability,Pneumatic probeThe choice of material should be hard on the workpiece material. For example, high hard steel, tungsten carbon alloy, gems, etc., if you consider the service life, you can choose diamonds. If you can try to avoid the use of tungsten carbon alloy to measure aluminum, aluminum is easier to stick to carbon, will affect the measurement accuracy, the use of high hard steel or diamond to measure aluminum is just the right choice.
Not all gauges are in the vertical direction, and changing the contact length in the horizontal direction will change the reading if the workpiece you are measuring is moving at an Angle. For mechanical lever meters, you can install a dial with the appropriate magnification, or with simple mechanical compensation, if you use a horizontal inductance measuring head, you can be programmed to compensate to the amplifier.
5Whether the probe is in contact with the workpieceThere are also non-contact measurement methods when measuring, such as the air momentum meter has many advantages, between the crest and the trough of the micro-inch height, the air momentum meter is to take the average value of the outer surface of the part, but not all cases are applicable.
