HVAC Pressure Sensor
HVAC air pressure sensors are available to monitor volumetric flow rates and
pressures in tubing and rooms are crucial when it comes to adjusting heating or
cooling, ventilation, and humidity systems by most economic power ratios.

Differential Pressure Sensor
A differential pressure sensor or differential pressure transmitter is a device
for monitoring pressure changes at two position

PRESSURE TRANSMITTER
A Pressure Transmitter is a device that produces an output electrical signal
(ma or microvolt) that varies with the pressure it experiences. When pressure
is forced on the crystal chip inside the sensor and the deformed crystal
generates a signal. The signal will be transferred by the wire to a display or
monitor that can show the signal in value. For example: 4ma=0, 12ma =50 psi,
20ma=100 psi... Pressure sensors are used to inspect the pressure of the gas,
fluid, or another medium.

As a Pressure Transducer Supplier, LEFOO pressure control designs multiple
types of pressure sensor transducers at lower costs and good prices. The
pressure sensor transducer includes water level differential pressure sensor,
absolute vacuum pressure sensor, smart room temperature pressure sensor,
industrial digital hydraulic pressure sensor, piezoresistive pressure sensor,
pneumatic pressure sensor with display, OEM pressure sensor, etc.

PRESSURE TRANSDUCER
A pressure sensor transducer is a device that consists of a pressure sensor and
a signal amplifier, a pressure transducer will translate measured data into a
stronger electrical analog signal that can be read and shown on a display by
the program controller. A Pressure transmitter is a device that converts a low-
class electrical signal from a sensor or transducer to a higher class or a form
of data that is available for long distances transmission. Such as 4-20 mA or
485 digital output. These outputs can transmit over long distances. Some
transmitters can provide additional data about the device or process measured
as part of the communication. The(1-5,1-10)voltage signal is the most stable
signal in electrical noisy situations like energy-related industries.

THE DEFINITIONS OF ABSOLUTE PRESSURE, GAUGE PRESSURE, AND DIFFERENTIAL PRESSURE

Pressure Sensor

Pressure is the force that exists on the surface per unit area. There are three
types of pressure measurements: absolute pressure, gauge pressure, and
differential pressure. Absolute pressure is referred to the vacuum space (zero
atmosphere pressure). In practice, absolute piezoresistive pressure sensors
measure the pressure relative to a high vacuum reference sealed behind its
sensing diaphragm. Absolute pressure is the sum of gauge pressure(Pg) and
atmospheric pressure(Paytm). The acronym for (Kpa: Thousand Pascal) Bar or PSIA
(Pounds per Square Inch Absolute. ) Absolute pressure sensor and altimeter are
good options for weather monitoring. Usually the standard atmosphere
pressure=101.325 pascal=14.7 psi=1.01 bar.

Gauge pressure is actual pressure in a vacuum environment. it is an acronym for
PAG (Pascals Gauge) or PSIG (Pounds per Square Inch Gauge) Gauge pressure is
measured relative to the environmental atmosphere pressure. Weather conditions
and altitude changes directly influence the gauge. Gauge pressure is positive
for pressures above atmospheric pressure, and negative for pressures below it.
The average atmospheric pressure at sea level is 101.325 kpa.Gauge Pressure
=Absolute Pressure-Atmosphere Pressure. Kpa, Bar, PSI are used to describe
Gauge pressure value. For a commonly example, in our daily lives, we may pump
our car tires from 32 to 40 PSI by the gauge pressure.

Differential pressure is similar to gauge pressure, It is measured based on
atmospheric pressure, Differential pressure is composed of high pressure and
low pressure, and is usually used to monitoring filters in pipes or tanks when
it clogged. Differential pressure is usually an acronym for PAD (Pascals
Differential) or PSID (Pounds per Square Inch Differential, Kpa, and Bar).
Differential pressure is also used in boiler, high pressure or liquid pressure
or level check, and low pressure for an air pressure check. The two pressures
will indicate how many liquids are left in the boiler.

The units of pressure are Pascal (Pa, N / m2), pounds / square inch (PSI),
atmospheric pressure (atm), and bar. (Bar), an inch of mercury (inch Hg),
millimeter of mercury (mm Hg, torr), etc. The PSI and Bar are most commonly
used in sensor industries. Liquid Pressure is defined as the strength of a
liquid per unit area of its surroundings. For example, pressure (P) is a
function of force (F) and area (A). P = F / A, (fluid P gauge=pgh)
