A pressure relief valve may be used to guard against damage in the event that the unit is over-pressured. The SI unit for pressure is the pascal (N/m 2), but other common units of pressure include pounds per square inch (psi), atmospheres (atm), bars, inches of mercury (in. Hg), millimeters of mercury (mm Hg), and torr. Instruments used to measure pressure are called pressure gauges or vacuum gauges.

However, after 40 to 45 years of age, woman's blood pressure increases faster than does a man's. Other examples of safety incorporated into process control systems are rupture disks and blow out panels, a pressure switch that does not allow a pump to over pressurize a pipe or a temperature switch that does not allow the fluid flowing through a heat exchanger to overheat. Contents. Pressure. 6 INDUSTRIAL INSTRUMENTATION C-8\N-IND\BOOK1-1 1.4.1.6 Flow of Compressible Fluids in Pipes If the fluid is compressible, a flow rate can be obtained if the gas is considered ideal and the flow is considered adiabatic. The pressure acts directly on the piston and compresses the spring. Maintenance-free instrumentation with a These instruments are robust and used over a wide range. ATMOSPHERIC PRESSURE A pipe 100 mm diameter carries oil at a mean velocity of 2 m/s. Course Contents. A force of 5000 N acts on an area of 400 mm2. PRESSURE In resistive pressure sensors (a), strain gages pick up changes in pressure by bending or compressing.

A pressure vessel is a closed leak-tight container (normally cylindrical or spherical) designed to hold fluids (i.e, gases or liquids) at a pressure substantially different (higher or lower) from the ambient pressure. Presentation Summary : Instrumentation. They can be fitted with electric switches to set off alarms. Pressure drop devices • Venturi flow meters have advantage over orifice plate due to low loss coefficient • C d is the discharge coefficient (~ 1 for venturi & 0.6 for orifice) • Pressure transducer should be located at low temperature, if possible • Requires determination of density at meter inlet Δp where β = D t /D Δp Clipping is a handy way to collect important slides you want to go back to later. To achieve this, occlusive pressure is applied evenly around the limb. pressure of a fluid stays constant, the gauge pressure of the same fluid will vary as atmospheric pressure changes. Flow ==> Boiler Instrumentation Control is the control over the industrial boilers.
