Reluctance Pulse Pick up Transducer: This Reluctance Pulse Pick up Transducer is very suitable for the measurement of shaft speed and liquid flow. It is based on the principle that if the field of any…
Frequency Generating Transducer: Frequency Generating Transducer - Unlike variable parameter analog transducers, frequency and pulse generating transducers measure physical variables in terms of a pulse repetition rate. Since frequency is an analog quantity, these can…
Platinum Thin Film RTD Sensors: Platinum Thin Film RTD Sensors are manufactured by a very thin layer of platinum in suitable pattern to achieve smaller dimension and higher resistance, on a ceramic base. The deposition…
Phototransistor Construction and Working Principle: The sensitivity of a photo diode can be increased by as much as 100 times by adding a junction, resulting in an NPN device. A simple representation of the Phototransistor…
Photovoltaic Cell Working Principle and Types of Photovoltaic Cells: The Photovoltaic Cell Working Principle or solar cell, produces an electrical current when connected to a load. Both silicon (Si) and selenium (Se) types are known…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter elements. This activity of parent…
Turbine Flow Meter Working Principle: Turbine Flow Meter Working Principle - The Turbine Flow Meter is used for the measurement of liquid gas and gases of very low flow rate. It works on the principle…
Magnetic Flow Meters: Magnetic Flow Meters are the first type of flowmeters to be considered for high corrosive applications and for applications involving measurement of erosive slurries. These meters work on the principle of Faraday's…
Flow Measurement (Mechanical Transducers): The measurement of flow rate and quantity is the oldest of all measurements of process variables in the field of instrumentation. It is used to determine the amount of materials flowing…
Ultrasonic Transducer: Ultrasonic Transducer (sound vibrations above 20 kHz) are useful when we are concerned with rapid temperature fluctuations, temperature extremes, limited access, nuclear or other severe environmental requirements and measurement of temperature distribution inside…
