Absolute Pressure Gauges Principle
These instruments are used where pressures are to be measured independent of the natural fluctuations in atmospheric pressure. As a general rule all the known types of element and measuring…
Pressure Gauges with Capsule Sensor Principle
The capsule element comprises two circular-shaped, convoluted membranes sealed tight around their circumference. The pressure acts on the inside of this capsule and the generated stroke movement is shown by…
Pressure Gauges with Bourdon Tube Principle
Pressure gauges with bourdon tube Bourdon tubes are circular-shaped tubes with an oval cross-section. The pressure of the media acts on the inside of this tube which results in the…
Pressure Gauges with Diaphragm Sensor Principle
Diaphragm elements are circular-shaped, convoluted membranes. They are either clamped around the rim between two flanges or welded and subject to the pressure of the media acting on one side.…
Difference between PT100, PT1000, Nickel RTD and Balco RTD
Comparison of Different RTD Types : PT100 Vs PT1000 Vs Nickel RTD Vs Balco RTD Description Platinum RTD 100Ω wire wound and thin film Platinum RTD 1000Ω thin film Nickel…
Bellows
Principle: Bellows pressure element is works on the principle of Elasticity. Material of Construction : S.S., Copper Phosphorus bronze Uses : To measure pressure. Bellows is a thin-walled, one piece…
Strain Gauge Animation
A strain gauge is a long length of conductor arranged in a zigzag pattern on a membrane. When it is stretched, its resistance increases and Vice Versa. Strain gauges are…
Diaphragms
Is a relatively broad, shallow cup like form which is made of thin metal or flexible materials chosen for qualities that relate to elasticity, ease of forming and heat treatment,…
Two-Liquid Manometer Principle
The two-liquid manometer is used to measure very small pressures. This is because a very small applied pressure, will produce a large liquid movement. The basic arrangement is shown in…
Inclined-limb Manometer Principle
This design of manometer is shown on the figure. As the name " Inclined-Limb Manometer " suggests, the manometer limb is inclined at an angle to the horizontal. The effect…
