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)
