SI-10 Liquid pressure sensor

The liquid level sensor also called a water pressure sensor, or water pressure transducer.

The SI-10 series pressure sensor provides exceptional levels of stability,

and other performance specifications,

in a wide variety of enclosures from submersible to differential styles.

By using a sputtered sensing element,

which achieves a molecular fusion of a strain gauge material,

an insulating material, and the 17-4 PH ss sensing element,

the SI-10 series transmitter provides the most stable sensor construction possible.

Q & A

How does pressure sensor work?

What is the working principle of a pressure sensor?

A pressure sensor works by converting pressure into an analog electrical signal.

The demand for pressure measuring instruments increased during the steam age.

When pressure sensing technologies were first manufactured,

they were mechanical and used Bourdon tube gauges to move a needle,

and give a visual indication of pressure.

Nowadays we measure pressure electronically using pressure transducers and pressure switches.

What is a capacitive pressure sensor?

Capacitive pressure sensors typically use a thin diaphragm,

as one plate of a capacitor.

The applied pressure causes the diaphragm to deflect and the capacitance to change.

This change may or may not be linear,

and is typically on the order of several picofarads out of a total capacitance of 50-100 pF.

The change in capacitance may be used to control the frequency of an oscillator or to vary the coupling of an AC signal through a network.

The electronics for signal conditioning should be located close to the sensing element,

to prevent errors due to stray capacitance.

What are the various types of sensors used to measure pressure?

Pressure measurements can be taken to determine a range of different values,

depending on whether the pressure is relative to the atmosphere,

vacuum conditions, or other measuring factors.

Pressure sensors are instruments that can be designed

and configured to detect pressure across these variables.

Absolute pressure sensors are intended to measure pressure relative to a vacuum,

and they are designed with a reference vacuum enclosed within the sensor itself.

These sensors can also measure atmospheric pressure.

Similarly, a gauge pressure sensor detects values relative to atmospheric pressure,

and part of the device is usually exposed to ambient conditions.

This device may be employed for blood pressure measurements.

For more information on the differences between the gauge and absolute pressure.

How do vacuum sensors work?

Vacuum sensors are used to measure vacuum or sub-atmospheric pressures.

Vacuum means pressure below atmospheric.

Since the true vacuum is never attained,

the measurement is in respect to a near absence of gas pressure.

The vacuum can be measured using a conventional pressure sensor;

however, they typically do not resolve extremely low concentrations of gas,

due to poor signal-to-noise ratio.

Vacuum sensors rely on physical properties of gaseous molecules,

that are related to the number of such molecules per volume of space.


Sino-Instrument offers both pressure and differential pressure sensors,

in either silicon-based or foil based strain gage technology,

perfect for many types of applications in automotive,

aerospace, chemical, semiconductor manufacturing, and general industry.
