Sensor Tacho Generator

Sensor yang sering digunakan untuk sensor kecepatan angular adalah tacho generator. Tacho generator adalah sebuah generator kecil yang membangkitkan tegangan DC ataupun tegangan AC. Dari segi eksitasi tacho generator dapat dibangkitkan dengan eksitasi dari luar atau imbas elektromagnit dari magnit permanent. Tacho generator DC dapat membangkitkan tegangan DC yang langsung dapat menghasilkan informasi kecepatan, sensitivitas tacho generator DC cukup baik ...

Pressure Sensor

• Pressure and force transducers (load cell) – consists of elastic material and displacement sensors – measure quantity (i) strain or (ii) displacement – grouping: absolute gauge and differential types Figure 3.51 Diaphragm pressure sensor: flat-type diaphragm, (b) corrugated diaphragm, (c) media of capacitance • pressure sensor with diaphragm reliable, difficult to make, reproducible – measure strain with strain gauge ...

Rotameter Working Principle

The rotameter consists of a vertical tube with a hole in which the position of the buoy is considered vertical according to the flow rate through the tube (Fig. 3.41). For known flow rates, buoys remain stationary because of the vertical forces of differential pressure, gravity, viscosity, and the buoyancy will be balanced. So the ability to balance itself from ...

Proximity Detector

– (a) a reed switch that manipulates a connected or disengaged switch based on a magnetic field – (b) RF-lost due to a metal absorbing magnetic field (frequency 40-200 kHz) resulting in the RF detector down due to LC resonance circuit loading in the oscillator – (c) The capacitance detector observes the change of capacitance by the nonconducting material – ...

Fluid Flow Sensor

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. ...

Pipe Venturi

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 ...
