What Is An Oscillator Transducer

What is an Oscillator Transducer

An oscillator transducer is a type of transducer that can be used to measure force, pressure, or displacement by converting it a voltage, which can then be measured by a voltmeter. Oscillator transducer are mostly used as secondary transducers, with their output calibrated in terms of their input quantity. Oscillatory transducer consists of following parts

  • Mechanical linkage

  • Oscillator

  • Frequency modulator

  • Force summing member

Mechanical linkage: This is used to link the input quantity to the secondary transducer, i.e. oscillatory transducer, by actuating it. It may include gears or some other linkage system.

Oscillator: As we know oscillator are used to generate desired frequency. The oscillator used here consists of LC tank/circuit. The output frequency is generated according to the input source.

Frequency Modulator: The output frequency from the oscillator may need some modification for telemetry purpose. This modulation is achieved by frequency modulator. After modulation the output frequency is suitable for telemetry purpose.

Force Summing Member: This is used to change the capacitance or inductance of an LC oscillator circuit. It transfers the pressure to mechanical linkage.

Working of Oscillator Transducer

working of oscillator transducer
Working of oscillator transducer can be explained from the figure as:

  • The quantity to be measured like pressure is applied to the force summing device which transfers this pressure to mechanical linkage.

  • Mechanical linkage responds according to the magnitude of the pressure.

  • Mechanical linkage drives the dielectric medium inside the capacitor.

  • The movement of the dielectric medium inside the capacitor tends to change the capacitance.

  • Frequency of oscillator depends on capacitance and inductance. In case of change of any of these quantities the frequency changes.

  • The output of oscillator is a modulated output and can be modulated and calibrated in terms of pressure or force applied.

Advantages of Oscillator Transducer

  • This transducer measures both dynamic and static phenomena.

  • This transducer is very useful for telemetry applications.

Disadvantages of Oscillator Transducer

  • This transducer has very hunted temperature range.

  • It has a poor thermal stability.

  • It has a low accuracy and therefore is used only in low accuracy applications.

What is reactive power measurement?
What is reactive power measurement?
The power which exists in the circuit when the voltage and current are out of phase to each other, such type of power is known as the reactive power. The formula measures the reactive power in the circuitReactive Power Measurement & VarmetersReactive power measurement is critical as it indicates circuit power loss: low reactive power worsens load power factor, increasing system losses. Varmeters (volt-ampere reactive meters) measure reactive power and are categorized by circuit phases:Single

Classification of Electric Power Distribution Network Systems
Classification of Electric Power Distribution Network Systems
The typical electric power system network is categorized into three main components: generation, transmission, and distribution. Electric power is produced in power plants, which are often located far from load centers. As a result, transmission lines are employed to deliver power over long distances.To minimize transmission losses, high-voltage power is used in transmission lines, and the voltage is reduced at the load center. The distribution system then delivers this power to end-users.Types

Why is the Ground Wire Always Positioned Above the Overhead Power Lines?
Why is the Ground Wire Always Positioned Above the Overhead Power Lines?
Ground Wire in Overhead Transmission LinesThe ground wire (also called earth wire or OPGW) installed above phase lines in overhead transmission lines acts as a key protective and safety component. It provides lightning protection, ground fault defense, and helps prevent electrical system disruptions.In overhead transmission lines, positioning the ground wire above phase lines serves specific safety and performance purposes. Referred to as a "shield wire" or "static wire," this configuration has
