Fluid Flow Sensors (Flow Sensor)

Flow measurement known since 1732 when Henry Pitot regulate the amount of fluid flowing. In the measurement of fluid necessary to determine the amount and flow velocity vector at a point in the fluid and how the fluid changes from point to point. Measurement of fluid flow or censorship can be classified as follows: 1. Measurement of the quantity These ...

Measuring Flow In Thermal

a. Hot Wire Anemometer This method is quite simple: by using a wire heated by electric current, the current flowing in the wire is made to remain constant using a constant current source. If no air flow, the wire will cool (as we blow out the candles) by the cooling of the wire, the wire resistance decreases. Because of the ...

Mengukur Aliran Secara Thermal

a. Anemometer Kawat Panas Metoda ini cukup sederhana yaitu dengan menggunakan kawat yang dipanaskan oleh aliran listrik, arus yang mengalir pada kawat dibuat tetap konstan menggunakan sumber arus konstan. Jika ada aliran udara, maka kawat akan mendingin (seperti kita meniup lilin) dengan mendinginnya kawat, maka resistansi kawat menurun. Karena dipergunakan sumber arus konstan, maka kita dapat menyensor tegangan pada ujung-ujung ...

Basic Theory Potentiometer

Potentiometers available on the market consists of several types, namely: carbon potentiometer, potentiometer wire wound and metal potentiometer movie. 1. Potentiometer potentiometer carbon is made of carbon price is quite cheap but very low kepressian this potentiometer resistance is usually the price will be very easy to change due to contact shifting. 2. Potentiometer coil of wire (wire wound) is ...

Thermal Sensor

AIR CONDITIONING. Srivastava (1987), said temperature is one of the four basic quantity that is recognized by the International Measurement System (The International Measuring System). Lord Kelvin in 1848 proposed a thermodynamic temperature scale at a fixed point of the triple point, where the solid phase, the liquid and vapor are together in equilibrium, this figure is 273.16 ° K ...
