Gasboard-7500

Product catalog summary

Introduction
The Gasboard-7500 is an ultrasonic gas flow and oxygen sensor designed by Wuhan Cubic Optoelectronics Co., Ltd. It utilizes the ultrasonic velocity difference between upstream and downstream to measure gas flow and oxygen purity, making it suitable for integration into personal or medical oxygen concentrators.

Features

Measures oxygen concentration and flow using ultrasonic methods.
Compact size, stable, and high precision.
No routine calibration required.
Long lifespan of over 5 years.
Customizable for various applications.
Widely used in PSA oxygen generator industry for continuous monitoring, with data displayable on an LCD.

Comparison of Detection Methods
The document compares ultrasonic detection with zirconia and electrochemical methods:

Life Span: Ultrasonic sensors offer continuous monitoring with a lifespan of over 5 years, whereas zirconia and electrochemical sensors have shorter lifespans and require frequent calibration.
Flow Monitoring: Ultrasonic sensors support future digital display instruments, unlike the other methods.
Temperature Effect: Ultrasonic sensors include temperature compensation, effective between 0-45°C.
Calibration: Ultrasonic sensors are factory calibrated and do not require recalibration.
Monitoring Scale: Ultrasonic sensors are mainly used for binary gas environments, particularly in the oxygen industry.
Monitoring Method: Continuous monitoring is possible with ultrasonic sensors, unlike the other methods which are not fully continuous.
