A current meter is used to measure the velocity of flow in the channel. It consists of a wheel or revolving element on which the conical buckets of V-shaped vanes are fixed. So, the current meters are classified on the basis of...

Tactile pressure sensors are used to detect the pressure distribution between a sensor and a target. They are often used on the robot grippers or flat tactile arrays to identify whether the finger is in touch with the target...
A piezoelectric sensor is a device that uses the piezoelectric effect to measure pressure, acceleration, strain or force. When pressure, force or acceleration is applied to piezoelectric materials such as quartz crystal, PZT...
The bourdon tube pressure sensor instrument is one of the oldest pressure sensing instruments in use today. It is widely used in applications where inexpensive static pressure measurements are needed. The bourdon tube consists of...
The bellows pressure sensor is a one-piece, collapsible, seamless metallic unit that has deep folds formed from very thin-walled tubing. It looks like a stake of capsules. It is more sensitive than the diaphragm and capsule...
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...
