Gas Control Systems

The Qubit A365 Gas Controller set to PID mode  energizes  a 3-way solenoid valve to  inject control gas (e.g. CO₂) into the carrier gas (e.g. air) to regulate the CO₂ level in a chamber.  The levels of sub-sampled control gas are measured by Qubit’s CO2 analyzer.  A feedback signal is sent back to the Gas Controller A365 which activates or deactivates the solenoid valve to control the flow, and thereby the chamber level, of CO2.

Features

• Control of gas concentrations in a chamber via feedback control of a solenoid
• Ability to cope with slow changes in the controlled gas due to plant or animal activity
• Flexible system that can be used for control of various gases (by changing the gas analyzer)
