Most treadmills monitor intensity with hand sensors that measure your heart rate, but that's not the most accurate approach. A better way to gauge your effort is to use what's called the rate of perceived exertion, which involves ranking your sense of how hard you're working on a 1-to-10 scale, with 1 being low and 10 being high. For instance, a rate of 5 to 7 is consistent with a moderate-intensity level where you work hard, but can maintain a conversation and do not overexert yourself. http://www.tecmofitness.com/cardio-equipment/treadmill/

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/

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/
