Harsiddhi Air Solution produces sophisticated Gas Analyzers and Sensors designed to measure, monitor and control the concentrations of gases in industrial settings with unparalleled precision.
We design our gas analyzers to maximize safety, efficiency, and purity in all types of industrial gas generation systems, including PSA Nitrogen Plants, PSA Oxygen Plants, Ammonia Crackers, Purifiers, and De-Oxo Systems. Our combined sensor technologies provide precision gas composition monitoring and measurement systems to measure and maintain the integrity of the process and guarantees purity.
What Are Gas Analyzers and Sensors?
Gas Analyzers and Sensors are accurate instruments designed to detect and measure the concentration, or amount, of gases such as oxygen, nitrogen, hydrogen, carbon dioxide, and ammonia in a gas mixture. These instruments allow users and operators to monitor and maintain the quality of the gas they are working with, detect leaks, and improve process safety in manufacturing and production facilities.
At Harsiddhi Air Solution, our analyzers utilize state-of-the-art technologies for detection of gases – electrochemical, infrared (NDIR), paramagnetic, zirconia, thermal conductivity and others – to deliver responses that are fast, stable, and very reproducible, even in difficult industrial settings.
Working of Gas Analyzers and Sensors
- Sample Gas Intake: A gas sample is drawn from the process line into the analyzer.
- Sensor Detection: Sensors measure the concentration of specific gases through a chemical or physical reaction (depending on the sensor).
- Signal Processing: The measured signal is converted into digital data, displayed on an HMI, or communicated to the PLC or SCADA system.
- Automatic Calibration & Alarms: Smart systems can automatically calibrate, and automatic alarms can be activated when gases exceed the threshold.
- Data Logging: Continuous monitoring of process gas allows for reliable data collection and effective process control.
