SI-2088 Industrial Pressure Transmitter

SI-2088 industrial pressure transmitter consists of a diffused silicon sensor and a signal module. It uses the piezoresistive effect of semiconductor silicon material to realize the conversion of pressure and electrical signals. The measured pressure acts on the stainless steel diaphragm, and is transmitted to the sensitive element through the silicone oil between the diaphragm and the sensitive element. Since the sensitive element has a good linear relationship with the applied pressure. Therefore, an accurate measurement of the pressure is achieved.

Learn More About Industrial Pressure Transmitter

SI-2088 Industrial Pressure Transmitter is a Diffusion Silicon pressure transmitter.

Diffused silicon pressure transmitters convert pressure signals into electrical signals. Then the electric signal is amplified and filtered by the preamplifier. The A/D conversion module sent to the CPU performs conversion from analog to digital. Finally, the CPU performs data processing and display and PWM output.

The pressure of the measured medium acts directly on the diffused silicon diaphragm of the sensor. Make the diaphragm produce a small displacement proportional to the medium pressure. Under normal working conditions, the maximum displacement of the diaphragm is not more than 0.025mm. After the electronic circuit detects this displacement, it converts this displacement into a standard industrial measurement signal corresponding to this pressure.

When overpressure, the diaphragm is directly attached to the solid ceramic substrate/diffused silicon, because the gap between the diaphragm and the substrate is only 0.1mm. Therefore, the maximum displacement of the diaphragm during overpressure can only be 0.1 mm. Therefore, it is structurally guaranteed that the diaphragm will not be deformed too much. The sensor has good stability and high reliability.

A pressure transducer is an instrument that converts a pressure variable into a standard output signal. There is a certain functional relationship between the pressure variable and the output signal.

According to different working principles, pressure transmitters can be divided into the following types:

(1) piezoresistive pressure transmitter

A piezoresistive transducer applies pressure to the front surface of a diaphragm. Under pressure, the diaphragm deforms to some extent. Thick-film resistors are printed on the back of the pressure-sensitive diaphragm, forming a Wheatstone bridge. Under the piezoresistive effect, the bridge generates a corresponding voltage signal. This signal is proportional to the excitation voltage.

(2) Piezoelectric pressure transmitter

Piezoelectric transducers have a positive piezoelectric effect. The positive high voltage effect is that a certain external force acts on the electrolyte to deform it. Polarization occurs inside the electrolyte, producing different positive and negative charges on its two sides.

When the external force ceases to act, the electrolyte returns to an uncharged state. The polarity of the charge changes with the direction of the force. The electrolyte also deforms when an electric field is applied in the polar direction of the electrolyte. The deformation of the electrolyte will disappear after being offset, which is the inverse piezoelectric effect.

(3) Strain pressure transmitter

The strain gauges are glued together using a special adhesive, which causes mechanical strain. When the force on the object changes, the resistance strain gauge will also deform to a certain extent. This affects the resistance value and changes the voltage across the resistance. However, in this case, the change in resistance value is small.

A strain bridge is usually formed, enlarged by the instrumentation amplifier, and finally passed to the processing circuit display or actuator.

(4) Capacitive pressure transmitter

Capacitive pressure transmitters are divided into two types: electric and pneumatic. The normalized input signal of the former is a DC signal, and the output signal of the latter is gas pressure.

The two pressures of the measured medium are respectively input into the high pressure chamber and the low pressure chamber. Use Friendship Resource Network on the isolation diaphragm on both sides of the sensitive element. The electrodes on the measuring diaphragm and the insulating sheets on both sides form a capacitor.

When the pressure on both sides is different, the module will be displaced, and the current on both sides is also different. Under the action of oscillation and regulation, a current, voltage or digital output signal is formed.

The pressure transmitter converts the measured liquid level, density and pressure signals of liquid, gas or steam into 4-20mA DC current signal output. It can also communicate with HART handheld. Use them for setting, monitoring, etc.

In practical engineering applications, pressure units are often regarded as pressure units. More common pressure units:

Megapascal (MPa); Kilopascal (kPa); Pascal (Pa)
The symbol of megapascal for the pressure unit is MPa; the symbol of kilopascal is kPa, and the symbol of pa is Pa

Pound force/inch2 (lbf/in2, psi)
The unit of pressure is lbf/in2, psi

Millimeters of mercury (mmHg)
The symbol for millimeters of mercury in pressure units is mmHg

inches of mercury (inHg)
The symbol for inches of mercury is inHg

mm water column (mmH2O)
The symbol for millimeters of water in pressure units is mmH2O

inches of water column (inH2O)
The symbol for inches of water column for pressure units is inH2O

Kilogram force/cm2 (kgf/cm2)
The kilogram force/cm2 symbol of the pressure unit is kgf/cm2

Physical atmospheric pressure (atm)
The physical atmospheric symbol for the pressure unit is atm

bar (bar); millibar (mbar)
The symbols bar and mbar for pressure units are bar and mbar

Pressure unit conversion:

0.1Mpa (MPa) = 100Kpa (kilopa) = 1bar (bar) ≈ 0.98atm (standard atmospheric pressure) ≈ 1kgf/cm2 (kg force/cm2) ≈ 14.5psi

Gauge pressure is atmospheric pressure as a reference;
Absolute pressure is a state relative to vacuum;
Sealed gauge pressure is a standard atmospheric pressure encapsulated in the sensor;

We generally refer to pressure transmitters that measure gauge pressure as gauge pressure transmitters. This is also the most commonly used type of pressure.
