Types of Bourdon Tube
Basically they are designed to follow the physical law that, within the elastic limit, stress is proportional to strain (Hooke’s Law), that is deflection is proportional to the pressure applied.…
4-20mA Junction Box versus Fieldbus (FF) Junction Box
How will a field JB of conventional 4-20mA connection look different from that of FF JB. Conventional Junction box Convectional Junction box contains Terminal Strip and Earth Strip/earth bus bar…
Using of MCT instead of Cable Glands on the Cabinets
Using of MCT instead of Cable Glands on field installed cabinets In local cabinet installed on plant, on skid packages, usually cable entries is from bottom. Normally, in order to…
Differential Pressure Gauge Principle
The difference between two pressures is determined directly and shown on the differential pressure gauge. Here again all of the measuring elements known from overpressure gauges and the measuring principles…
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…
