Process Control

Food processors using Individual Quick Freeze (IQF) CO2 cryogenic freezer tunnels have found CO2 Gas Sensors necessary to measure area CO2 gas levels in order to provide working personnel safety. The installation of the Model 2156 CO2 gas monitor will meet the USDA requirements for CO2 gas monitoring and provide a proper level of CO2 measurement safety.

A new and emerging process is to use pressurized Carbon Dioxide CO2 gas sensor treatment in juice processing to inactivate food enzymes through creating a carbonic acid liquid. The result is maintaining the nutritional benefits and flavor of fresh squeezed juice while extending the storage and usable shelf life.

Seafood processors have found that the use of a gas mixture of Carbon Monoxide CO sensor, Carbon Dioxide CO2 sensor and Nitrogen N2 sensor allow for a stable and safe quality product, reduced growth of pathogenic bacteria, a longer microbiological shelf life and a attractive wholesome appearing product.

Dairy applications using Carbon Dioxide CO2 sensors during processing inhibits the growth of microorganisms that cause spoilage thus allowing for longer periods of storage prior to shipment and shelf life.

Control of CO2 sensor concentration levels is also used for the ripening and storage of fruits and vegetables.

                                                                                                                                                                                                                                  *Notes: all the DIGITAL models listed in the section below require an input power of 12VDC. The 12VDC ANALOG units have a 0-1 volt output and a 4-20mA current loop output, except where indicated. The 115/230VAC ANALOG units have a 0-5V output and a 4-20mA current loop output. All models are CO2 sensors, except where indicated (CO).
