Strain Gauge Displacement Sensor The strain gauge displacement sensor consists of a structure attached with the strain gauge that elastically deforms when subjected to a displacement. Strain gauge is attached to the object by a suitable adhesive. As the member is stressed, the resulting strain deforms the strain gauge attached with the structure. This causes

Capacitive Displacement Sensors A transducer that uses capacitance variation can be used to measure displacement. Elastic deflection of a membrane due to the applied force is detected by a capacitance variation. A highly sensitive displacement and proximity transducers can be constructed because the Capacitive displacement sensors transducer senses very small deflections accurately. Capacitive sensors can

Static characteristics Static characteristic of an instrument are the parameters which are more or less constant or varying very slowly with time. The following characteristics are static characteristics performance terminology. Range : Every sensor is designed to work over a specified range i.e. certain maximum and minimum values. The design ranges are usually fixed and

Directional Control Valves (DCVs) The primary function of any control valve is to direct, regulate the flow of fluid and regulate the pressure in various loading devices. Usually, directional control valves are used for sensing, processing, controlling which involves in the following functions. Controlling the flow by guiding and directing It to a loading line.

Most of mechatronics systems work based on motion or action by means of sort. This motion or actuation is caused either by a torque or force from which displacement and acceleration can be obtained. To obtain this force or acceleration, actuators are mainly used. Actuator is a device which provides enough force needed to start

Potentiometer displacement sensor is a primary sensor which converts the linear motion or the angular motion of a shat into changes in resistance. It is a type of resistive displacement sensor. Linear potentiometers are sensors that produce a resistance output proportional to the linear displacement or position. Linear potentiometers are essentially variable resistors whose resistance

Pneumatic and Hydraulic Actuation Clamps Generally, the above mentioned pneumatic and hydraulic clamps are actuated by mechanical means. Sometimes, these are actuated by hydraulic or pneumatic methods where large production quantities are required. It facilitates faster clamping, uniform and equalised clamping pressure and less operator fatigue. It also provides an accurate controlling over clamping pressure.

Sensors and Transducers Sensors transducers are devices which produce proportional output signal (mechanical, electrical magnetic, ctc.) when exposed to a physical phenomenon (pressure, temperature, displacement, force, etc.). Many devices require sensors for accurate measurement of pressure, position, speed, acceleration or volume. Transducers are devices which converts an input of one form of energy into an

Microprocessor Based Controllers Microprocessors are essential to many of the products we use every day such as TVs, cars, radios, home appliances and of course, computers. Microprocessor based controllers are also called as microcontrollers. Microcontroller is a digital integrated circuit which serves as a heart of many modern control applications. Microprocessors and microcontrollers are similar

Principles of Clamping Principles of clamping devices are used to hold the workpiece in the correct relative position in the jig or fixture. It should ensure that the workpiece is not displaced under the action of cutting forces. For efficient operation, firm clamping of the workpiece is a must. An inadequate clamping may always prove
