Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.
The screw gauge was invented by William Gascoigne around the year 1638. Gascoigne was a renowned astronomer and mathematician from England.

The instrument is called a screw gauge, or more often a micrometer, because it uses a screw to amplify a very small movement so that it can easily be read. The heart of the screw gauge is a very accurately ground thread, usually of 0.5mm pitch, so that the axial movement of the screw corresponds to a much larger movement of a barrel which carries a scale. The instrument can be difficult to read because two readings have to be added, one measuring to 0.5mm the linear motion of the screw, and the other on the barrel giving the 1/100 ths. To some extent this instrument has been superseded by the electronic digital version, which does not incorporate a screw thread. A different gauge, called a thread gauge, comprises a set of metal blades with serrated edges which can be used to identify different screw threads by matching the right blade to the thread by trial and error.

The anvil on a micrometer screw gauge is used to support and hold one end of the object being measured. It helps to ensure that the object is positioned correctly for accurate measurements to be taken by the gauge.
Our laboratory screw gauge has a pitch of 1 millimeter.

The sleeve in a micrometer screw gauge helps to accurately measure small distances by providing a scale with markings that align with the spindle scale for precise readings. This allows for measurements to be taken with high precision and accuracy.
The pitch of a screw gauge refers to the distance traveled by the spindle per revolution. The least count of a screw gauge is calculated using the formula least count = pitch / total number of divisions on the circular scale. It represents the smallest measurement that can be read on the screw gauge.
the inventor of micrometer screw gauge is William Gascoigne.
No, a zero error in a screw gauge indicates that the initial reading is not starting from zero. So, 47mm cannot be a zero error unless the screw gauge is not calibrated correctly.
The sleeve on a micrometer screw gauge is used to provide fine adjustment of the measurement by rotating it to move the spindle in or out slightly. This helps in achieving accurate and precise measurements by allowing the user to make small adjustments without needing to rotate the thimble.
A micrometer (or micrometer screw gauge) measures the volume of a screw.
The spindle in a micrometer screw gauge is responsible for making contact with the object being measured and moving along the pitch scale to take measurements. It is rotated to bring the object into contact with the anvil, allowing for precise measurements of small objects with high accuracy.
