1. During assembly, attention should be paid to the coordination
between the core size and the transmitter housing to achieve the
required tightness.
2. When assembling the housing, ensure that it is vertically
aligned and apply pressure evenly to avoid damaging the
compensation plate.
3. If the measured medium is not compatible with the core diaphragm
and housing material (316L), special instructions should be
provided when placing the order.
4. Avoid pressing the sensor diaphragm with your hands or sharp
objects to avoid deformation or puncture of the diaphragm and
damage to the core.
5. Keep the pressure port of the gauge pressure core open to the
atmosphere to prevent water, water vapor or corrosive media into
the negative pressure chamber of the gauge pressure core.
1. What is a pressure sensor?
A pressure sensor is a device that measures the pressure of gases
or liquids. It converts the physical pressure into an electrical
signal that can be read and processed by control systems or
monitoring equipment.
2. How does a pressure sensor work?
Pressure sensors operate by using different technologies, such as
piezoresistive, capacitive, or piezoelectric elements, to detect
changes in pressure. When pressure is applied, it causes a change
in the physical properties of the sensing element, which is then
converted into an electrical signal proportional to the pressure.
3. What are the types of pressure sensors?
Piezoresistive Pressure Sensors: Use the piezoresistive effect in
materials like silicon to measure pressure.
Capacitive Pressure Sensors: Measure changes in capacitance caused
by the deformation of a diaphragm under pressure.
Piezoelectric Pressure Sensors: Use materials that generate an
electrical charge in response to applied mechanical stress.
Optical Pressure Sensors: Utilize light modulation to measure
pressure changes.
Resonant Pressure Sensors: Measure pressure by detecting changes in
the resonant frequency of a sensing element.
