Details of ABB AO910 diffused silicon pressure transmitter:

The AO910 diffused silicon pressure transmitter is an important measuring device. Its basic working principle is that when the pressure signal acts on the sensor, the pressure sensor converts the pressure signal into an electrical signal. After differential amplification and output amplifier amplification, it is then converted into a 4-20mA standard current output signal that is linearly related to the liquid level pressure of the measured medium (liquid) through V/A voltage and current conversion.

This type of transmitter has many advantages and characteristics, such as:

Good temperature characteristics: Due to the use of advanced technologies such as laser resistance modulation and computer compensation, as well as clever control of diffusion concentration, it overcomes the defect of high temperature coefficient of semiconductor chips themselves, achieving a high level of zero and full temperature drift of the transmitter, and expanding the temperature range of use.

Intrinsic safety explosion-proof: The diffused silicon pressure sensor and transmitter have the characteristics of low current, low voltage, and low power consumption, and belong to the intrinsic safety explosion-proof type products. They have obtained the explosion-proof certificate issued by the national safety explosion-proof agency.

High reliability and anti-interference performance: Due to the use of stainless steel material and special protective structure, as well as a series of protection measures such as lightning protection, anti-interference, overvoltage resistance, overcurrent resistance, etc. for amplification circuits, the reliable sealing and anti-corrosion ability and ability to resist harsh working environments are improved, fully suitable for the needs of general industrial field measurement and control.

The application fields of AO910 diffused silicon pressure transmitter are very extensive, including industrial automation, food safety, and energy production. In the field of industrial automation, it can be applied to pressure measurement and control of various equipment such as compressors, refrigerators, pumps, etc., to ensure efficient and safe production. In the field of food safety, it can measure and control the pressure of various containers and equipment on food production lines, ensuring that all food production and testing meet hygiene and safety standards. In the field of energy production, it can measure and control the pressure of gas pipelines, heat pipelines, oil storage tanks and other devices and containers, as well as monitor various pressure values during the energy production process.

In addition, the AO910 diffused silicon pressure transmitter also has some specific technical specifications, such as a pressure range of -0.1~900MPa, medium temperature range of -20~300 ℃, power supply voltage of 12-24VDC, output signal of RS485, installation thread of G1/4NPT, accuracy of 0.075, explosion-proof grade of ExiaIICT6, protection grade of IP68, diaphragm material of 316LSS stainless steel, etc.
