Inductive sensors utilize inductance change • as a result of the movement of a ferromagnetic core within the coil • due to an approaching ferromagnetic material The position sensor Figure 3.26: (a) Core shifted flat (b) Core I bergser spin (c) The series of variable inductance Reader circuit inductance change • two inductors arranged in a bridge circuit, one as ...

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

– utilizing silicon as a measuring material and diaphragm, the circuit can be integrated – more sensitive than metal because strain (displacement) and piezoresistive properties appear together – always use 4 gauge in bridge, problem faced gauge is not identical very sensitive to temperature – alternative solutions: excitation current bridge voltage compensation amplifier amplification compensation Figure 3.53 Straingage piezoresistif: (a) ...

Measurement speed digital way can be done by way of inductive, capacitive and optical. Measurements by means of induction was performed using a serrated rotor, stator is made of a coil wound on a permanent magnet. The output of this sensor in the form of voltage pulses. The use of this method is quite simple, very practical without requiring complex ...

Potentiometers available on the market consist of several types, namely: carbon potentiometer, wire wound potentiometer and metal potentiometer film. 1. Potentiometer of carbon is a potentiometer made of carbon materials the price is quite cheap but the potentiometer kepressian is very low usually the price of resistance will be very easily changed due to contact shift. 2. Wire wound potentiometer ...

Another form of flow measurement with different pressure is the venture pipe. In the venture pipe, accelerator fluid flow is done by forming a funnel so that the flow can still be maintained to remain laminar. The first tensile sensor (P 1 ) is placed at the first pressure angle and the second pressure sensor is placed on the plaing ...
