Rotation sensor is a type of sensor used for measuring rotary displacement. They can measure these rotary movements in either clockwise or anticlockwise directions. Rotation sensors are used in a variety of environments and applications to ensure the components within the device are working correctly. They are available in different technologies and each one has their own way of working with different advantages. http://www.wintopok.com/sensor/rotation-sensor/

Pressure transmitters are routinely used in a wide range of industrial sectors. Offshore drilling and oil exploration commonly utilize pressure sensors to measure differential values between the interior and exterior of pressure sensitive equipment. Distinct parameters must be maintained to ensure drilling and acquisition processes are carried out to an ethical and efficient standard. This is also true of on-shore petrochemical, gas, and chemical facilities. http://www.enbbonsensor.com/pressure-sensor/

A control valve receives the information from various sensors and transmitters in a control loop and processes that data to manage the control of the fluid parameter. The following figure shows a typical control loop for a control valve. There are many different types pf control valves, such as straight stroke control valve, single seat control valve, cage guided control valve, micro flow control valve, cryogenic control valve, bellow seal control valve, fluorine lined control valve, high pressure control valve, angle stroke control valve, ball control valve, etc. http://www.lozosevalve.com/straight-stroke-control-valve/cryogenic-control-valve/

Smart grids contain sensors that measure and transmit data to automatically adjust electricity flows according to supply and demand. Energy managers can use this information to adjust the grid and respond to problems in real time, making managing the grid far more efficient and improving fault detection without the need for technicians. The grid also enters people’s homes by communicating with smart power meters, which can turn on appliances during periods of surplus, when electricity is cheaper. This means smart grids can: http://www.asntegeosynthetics.com/

That is why engine management systems are very important. Engine management system is Engine Control Units (ECU) which receives signals from variety of sensors, make calculations and send output signal to various functions of a vehicle to ensure efficient operations. http://www.hiboriddhn.com/vehicle-control-system/engine-management-system/
