In Situ Host utilizes the hardware interface module to acquire the signals necessary to synchronize the analysis with the process. In addition, this unit is equipped with relays such that actions can be taken in the event of an alarm condition. This unit is called the "Signal Processor 100". The unit interfaces up to 8 RGAs and their remote sensors with In Situ Host. By combining system state sensors with gas analysis information, an advanced process control solution (APC) is achieved.
RGA Automation
The first obstacle to automation is a lack of synchronization. Over 95% of RGAs in use are not functionally automated. The user initiates the data collection, and the data is collected continuously at a steady sample rate until a certain amount of time has elapsed, or until the data file reaches a certain size. The analysis treats the data at any given point identically.
