Definitions • Pressure Definition from Physic
Pressure is force distributed over, a surface. The pressure P
/
of a force F distributed over an area A is defined as: P = F/A
• Atmospheric Pressure
Atmospheric Press re
pressure is the force of pressure exerted by the earth's
atmosphere. Atmospheric pressure at sea level is
equivalent to 14.695 psia. The value of atmospheric
pressure decreases with increasing altitude.
Page 6 of 152
• Barometric Pressure
Barometric pressure is the same as atmospheric pressure.
• Hydrostatic Pressure
y
Hydrostatic, pressure is encountered in liquid level applications.
Hydrostatic pressure is the pressure below the liquid surface
exerted by the liquid above.
• Line Pressure
Line pressure is simply the amount of pressure, or the force per
unit area, exerted on a surface by the flow parallel to a pipe wall.
• Static Pressure
Static pressure is the same as line pressure
Static pressure is the same as line pressure.

or static pressure.

• Absolute Pressure
Absolute pressure is a single pressure measurement with a
reference to a full, or p
perfect vacuum. Absolute p
pressure is the
measurement of the process pressure in excess of full vacuum or
0 psia. Zero absolute pressure (0 psia) represents a total lack of
pressure‐ For example, space is considered to be a full vacuum.
• Gauge Pressure

Gauge pressure is a single pressure measurement that indicates
atmosphere Gauge pressure represents the positive difference

between atmospheric pressure. You can convert gauge pressure
to actual atmospheric pressure value to the gauge pressure
equivalent to 24‐7 psia 0 psig is equivalent to 14.7 psia.

t atmospheric
to

Vacuum pressure is the measure of the depression of process
pressure below atmospheric pressure.
pressure
Vacuum pressure is generally measured in cm or inches of H20.
For example,
example 14.7
14 7 psia is equivalent to 407.5
407 5 inches of H2O.
H2O
Therefore, a pressure of 10 inches of H2O vacuum implies
process pressure is depressed 10 inches below atmosphere. Or
10 inches of H2O vacuum is equivalent to 397.5 inches of H20
absolute. Vacuum pressure is typically measured using a gauge
pressure transmitter with an elevated zero calibration.

Electromechanical Strain Gage
Electromechanical Strain Gage Strain gage sensors convert pressure into
relatively small resistivity changes. The change in resistance typically affects
the four legs of a Wheatstone bridge circuit, Figure 7‐1. When all the resistive
legs of the bridge circuit are balanced,
balanced and when the circuit is energized,
energized the
voltages read at test points 2 and 3 are equal. Strain gage sensors located in the
primary sensor usually take the place of two of the resistor legs in a
g circuit. Fixed resistor networks in the transmitter
Wheatstone bridge
electronics take the place of the other two legs. When there is zero pressure
applied to the transmitter, the resistance of the strain gages balances the fixed
resistors in the transmitter electronics and there is no voltage differential
across the

the resistance of the strain gages changes, unbalancing the bridge, and creating
a proportional differential voltage across the test points. The transmitter
electronics converts this voltage signal into a 4

Strain gage transducers are extremely sensitive to temperature effects. This is
because the resistance of the strain gage element can be affected by
temperature as well as applied stress. Extreme care must be taken in the design

• Variable Capacitance
Variable capacitance transducers sensor operates as follows. An increase in pressure on
the process diaphragm is transmitted through the fill fluid to the ceramic diaphragm in
the capacitance sensor. The pressure increase causes the diaphragm to bulge, thus
changing the distance between the diaphragm and the reference plate.
plate This change in
distance is very small. The change in the ratio of the C‐ and C+ capacitance feeds the logic
circuit of the transmitter. Increased output from the logic circuit is converted to dc
voltage and amplified by the gain and summation circuit. The signal from the gain and
summation circuit is applied to the output current regulator through the zero and
span circuit. The output current regulator
produces an increase in transmitter output current, which is proportional to
the increase in process pressure.

The advantages of capacitance sensing for pressure measurement include:
‐ good accuracy, linearity, hysteresis, repeatability and stability

• Variable Reluctance
Variable reluctance elements are being employed to detect small
displacements of capsules or other sensors for direct coupling between
pressure sensitive elements and amplifier circuits, Figure 7‐3. The
variable reluctance pressure sensor, the inductance in a pair of coils is
affected by changes in the magnetic coupling of the diaphragm, which
is mounted between the two coils. With applied pressure, the sensing

Piezoresistive
Piezoresistive sensors have come into wide use in recent years, they can be considered the
semiconductor technology version of the Electromechanical Strain Gauge that we have already
described. The Piezoresistive sensor consists of a semiconductor element that has been doped to
obtain a Piezoresistive effect. Its Conductivity is influenced by a change (compression or stretching of
the crystal grid) that can be produced by an extremely small mechanical deformation.
deformation As a result,
result the
sensitivity of monocrystalline sensors is higher than that of most other types. In particular higher than
the standard strain gauges, whose resistance changes only with geometrical changes in the structure.
Therefore Piezoresistive sensors are 10 to 100 times more sensitive than metal strain gauges. A
semiconductor element in a wafer format provides very high mechanical strength and elastic
behaviour up to the point of mechanical breakdown, yielding sensors that exhibit only
minor response to mechanical aging and hysteresis. But strain sensitivity in semiconductors is
temperature dependent and they must be compensated accordingly. Specific advantages are:
‐ High sensitivity, >10mV/V
‐ Good linearity at constant temperature
‐ Ability to track pressure changes without signal hysteresis, up to the destructive limit
Disadvantages are:

The Piezoresistive sensors must not be confused with the piezoelectric sensors. These one
produce a surface voltage potential difference when stressed in certain directions. Quartz, Rochelle

meter. They can be used in resonant transmitters.

Reasons of Using Remote Seals
fU i R
t S l
In pressure transmitter directly connected to process piping by the use of
impulse lines, the process fluid leaves the piping, fills the impulse lines and
enters the bodyy of the transmitter. Remote seals are recommended for all
applications where it is necessary to prevent the fluid to leave the piping, or to
enter the transmitter because of:
‐ The process fluid is highly corrosive
‐ The process fluid is dirty, solid laden, or viscous and can foul the
impulse line
‐ The p
process fluid can solidifyy in impulse
p
line or the transmitter
body, because of temperature decrease
‐ The process fluid is too hazardous to enter the area where the
transmitter is located
‐ The transmitter body must be located away from the process for easier
maintenance
‐ The process temperature exceeds the recommended maximum limits
for the transmitter

the transmitter cannot be utilized for food applications, because in case
of leakage they could poison the process fluid. Corrosion is the gradual
destruction of a metal by chemical or electrochemical means. It is
affected by several factors, from the combination of chemicals, even if
present in small amounts, to temperature. As an example if the
p

threat for stainless steel. Therefore Manufacturers cannot guarantee
that a material is suited to a particular application under all possible
process conditions. It is the user’s responsibility to make a careful
analysis of all process parameters when specifying materials. Other

penetrate Monel in high hydrogen concentration applications. When used as a diaphragm

• Gold‐Plated Hastelloy C or Monel or SST
Hastelloyy C, like Monel and SST allows the p
permeation of Hydrogen
y g therefore avoided as a
diaphragm material for Hydrogen service. Indeed Hydrogen atoms can through the
transmitter diaphragms, which are very thin, once reached the fill fluid, combine to form
molecular hydrogen. Because molecular hydrogen is too large to back through the
diaphragm it gets trapped and forms bubbles in the fill fluid. These can severely affect
transmitter performance. Plating these materials’ diaphragm with gold provides
protection against hydrogen in all cases of high process pressure and temperature, which
increase the permeation Another form of protection is available from ABB: a hydrogen
preparation (corrosion gel), which is applied to the instrument’s diaphragm to reduce
Hydrogen permeation. Both these protections are not available for the single port family
off transmitter.
