In order to improve the sensitivity, two corrugated diaphragms are combined by arranging these in back-to-back and sealed together at the periphery to obtain shell-like shape as shown in fig(capsule pressure sensor) . These are...

The diaphragm pressure sensor uses the elastic deformation of a diaphragm (i.e. membrane) to measure the difference between an unknown pressure and a reference pressure. Diaphragm is a thin circular elastic membrane made of...
This is an example for absorption type hydraulic dynamometer. Principle: When a conducting material moves through a magnetic flux field, voltage is generated, which causes current to flow. If the conductor is a wire forming, a...
Measuring the strain induced in a shaft due to an applied torque has been the most common method used for torque measurement in recent years. Torque transducers based on strain measurement are normally made by applying strain...
The main features of CNC – CMM are shown in fig. The stationary granite measuring table, length measuring system, air bearings, control unit and software are the important parts of CNC and CMM. Stationary granite measuring...
The below fig shows the layout of a computer controlled CMM, a flexible measuring centre. The measurements, inspection of parts for dimension form, surface characteristics and position of geometrical elements are done at the same...
The optical setup for the X-axis calibration is shown in fig below. In this fig the laser head is mounted on the tripod stand and its height is adjusted corresponding to the working table of CMM. The interferometer contains a...
The various types of CMM Co-ordinate measuring machine are, Cantilever type. Bridge type. Horizontal boring type. Vertical boring type. Cantilever type It is easy to load and unload, but it is most sensitive to mechanical error...
Construction of CMM: The co-ordinate measuring machines has movements in X-Y-Z which can be easily controlled and measured. Each slide in three in three directions has transducer which gives digital display and senses +ve/-ve...
Coordinate measuring machine are used for the measurement of length over the outer surfaces of a length bar or any other long member. The member may be either rounded or flat and parallel. The measuring machine are more useful...
