Description
If dimension X is less than 1.2 times the tip diameter, the
measurement will be affected by the attachment plate.
If dimension Y is less than 3 times the tip diameter, the
measurement will be affected by the attachment plate.
If the attachment plate around the sensor top is
chamfered, it will be affected by the attachment plate.
If the target and the sensor top are not parallel
(dimension X1 and X2 are not the same), it will affect the
reading.
If dimension X is less than the minimum linear range from
sensor tip specification for the sensor, the measurement
will not be
accurate.
