Inductance Type Pressure Transducers Principle
The inductance-type transducer consists of three parts: a coil, a movable magnetic core, and a pressure sensing element. The element
Capacitive Type Pressure Transducers Principle
Capacitive-type transducers, illustrated in Figure, consist of two flexible conductive plates and a dielectric. In this case, the dielectric is
Bridge Circuit Construction
Figure 1 shows a basic bridge circuit which consists of three known resistances, R1, R2, and R3 (variable), an unknown
Thermocouple Construction
A thermocouple is constructed of two dissimilar metal wires joined at one end. When one end of each wire is
Resistance Temperature Detectors (RTD) Construction
The RTD incorporates pure metals or certain alloys that increase in resistance as temperature increases and, conversely, decrease in resistance
Applications of Needle Valves
A needle valve is a type of valve having a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only
Blowout preventer (BOP) Principle
A blowout preventer (BOP) is a large, specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the
Flame Arrester Principle
A flame arrester (also spelled arrestor), or flame trap is a device that stops fuel combustion by extinguishing the flame.
What is Shutdown Valve?
A shutdown valve (also referred to as SDV or Emergency Shutdown Valve, ESV, ESD, or ESDV) is an actuated valve
Turbine Flow Meter Coefficient and Scaling Factor
Turbine flowmeter generates 10 pulses per gallon of liquid passing through it. Determine the meter coefficient and calculate the scaling factor.
