The reciprocating pumps is a positive displacement pump. It operates on the principle of actual displacement or pushing the liquid by a piston or plunger that reciprocates in a closely fitting cylinder. These pumps usually have...
Most of the conventional pressure gauges are of a mechanical type. These gauges embody on elastic element which deflects under the action of the applied pressure. This movement mechanically magnified and read with the help of...
Manometers is the device which is used for measuring the pressure at a point in a fluid by balancing the column of fluid by the same or another column of liquid. Simple Manometers Simple manometers are used to measure the...
The thermistor is a semiconductor device that has a negative temperature coefficient of resistance. Thermistors are non-metallic resistors, that is, semiconductors of ceramic materials. Basic Principle : The basic principle...
The most common method of temperature measurement uses the thermocouples. It is based on seeback effect. The thermocouple temperature measurement is based on creation of an electromotive force (e.m.f). Basic Principle : The basic...
The pressure thermometer temperature measurement is based on fluid expansion. Fluid expansion thermometer represent one of the most economical, versatile, and widely used devices for industrial temperature measurement...
This method refers to the identification of the temperature of a surface with the colour of the radiation emitted. The optical pyrometer compares the brightness of the image produced by the temperature source with that of a...
These pyrometers absorb only infra red pyrometer rays and measure temperature. At some high temperature, a surface starts emitting I-R rays in addition to visible light energy. These I-R rays are used with a detector and...
Thermal radiation pyrometers is electro magnetic radiation emitted by a body as a result of its temperature. Thermal radiation is in the wavelength region from about 0.1 to 100µm. The total radiation emitted by a blackbody is...
