AlgaeLab Systems Upgraded Sensors
June 21, 2013
lgae Lab Systems has upgraded its sensor products with a new line of durable process grade sensors. All sensors come with 3/4″ NPT threads on the front and rear of the sensor for convenient mounting configurations. The new sensors are rugged, affordable, and suitable for long term commercial use in sensing of pH, temperature, dissolved oxygen, nitrate, conductivity, optical density, light, and other parameters. All sensors can be connected to the AlgaeConnect™ Monitoring and Control system and allow for complete closed loop control and automation of all PBR or pond parameters.
AlgaeConnect collects data from sensors constantly and updates system behavior every minute based on light, algae growth rate, pH, and other readings. System behavior can be scheduled by the hour (CO2 delivery, mixing rate, etc.) or easily program an automatic control system. For example:
- Turn on a CO2 regulator to control pH level.
- Turn on a harvester pump when the algae density sensor reaches a threshold. Then, turn on a media refill pump.
- Automatically brighten indoor lights as the sunlight reduces, and dim them again in the morning.
- Control heaters, coolers, valves, relays, pumps, motors, and other devices.
Sensors include pH, temperature, optical density (algae growth), light, dissolved oxygen, conductivity, nitrate, gaseous CO2.
Auxiliary input ports allow you to connect 3rd party sensors, including 4-20 mA signals. The ports include +12V, -12V, and +5V supplies to power the sensors, and can be galvanically isolated using the ALS-ISO2 isolating cable.
The Optical Density sensor can be purchased separately and connected to any Windows PC over USB. It includes software with the same data recording and display features as the main system.
All data is stored for up to one year, and can be exported to an Excel spreadsheet and downloaded.
