It is used to change the signal from one form to another

It is a characteristic of a measuring instrument that might give different reading results for a specific input, depending on whether the input value is approached from higher or lower values

A temperature sensor has a range of 20 – 250 degrees C. A measurement results in a value of 75 degrees Celsius for the temperature. What would be the error if the accuracy is +/- 0.75% FS?

A temperature sensor has a range of 45 – 250 degrees C. A measurement results in a value of 50 degrees Celsius for the temperature. What would be the actual temperature reading if the span of the instument is +/- 0.75%?

A cement manufacturing plant is designed to produce 2,000 MT per day of cement clinker. Cement clinker can typically composed of CaO, SiO2, Fe2O3, and Al2O3. If the incoming silica and shale, as raw materials were known to be 20,000 MT and 180,000 MT, respectively. Calculate the following. Assume 300-day operation in a year.  In addition, the raw material is composed of limestone (87%CaO), iron oxide (24% Fe2O3), shale (60% SiO2, 25%Al2O3), and silica (90% SiO2).
