Construction and working of DC tachogenerator
Construction The basic constructions of DC tachogenerator are shown in fig. The dc tachogenerator is a small dc generator. The armature is driven by motor shaft whose speed is feedback. The rotor iron cored and field is
Advantages and disadvantages of monometer
There are some advantages of monometer which are given below. The monometer is suitable for low pressure applications. It has low cost. It is simple in construction. A manometer does not have to be calibrated against any
Advantages, disadvantages and applications of inclined monometer
There are some advantages of inclined monometer which are given below. The inclined monometer is used to measure very small pressure. It has very high accuracy. Inclined manometers do not have any parts that can wear or
How pressure is measured with inclined monometer?
The inclined type monometer is an enlarged leg monometer with its measuring leg inclined to the vertical axis by some angle. Due to inclination, scale expands and increases the sensitivity. When P1 and P2 are applied, then

Differential pressure (P) = P1 – P2 P = (ρ1 – ρ2)gh Where, ρ1 = density of liquid. Ρ2 = density of fluid whose pressure is to be measured. h = (h1 – h2) difference in fluid level g = acceleration
9271272519 – Cell solar panels
A solar cell is a sandwich of two different layers of silicon that have been specially treated or doped so they will let electricity flow through them in a particular way. The lower layer is doped so it has
