Data Collection & Reporting
A wide variety of data collection and reporting options are available to accommodate the spectrum of CEMs applications. For process control applications a simple analog or digital output signal providing concentration to an emission control system may be all that is required. For safety monitoring systems on furnaces or oxidizers, a simple contact closure or alarm may be sufficient.
Compliance monitoring typically requires data be stored, analyzed, and recorded, perhaps for reporting. This can be accomplished in a variety of means. Analog signals can be provided to a customer’s DCS or data capture system, or to a paper chart recorder for filing and storage. Electronic recorders with encrypted data storage can be provided. Data can be downloaded standard spreadsheets on the customer’s PC.
For larger and more complex CEMs, with more stringent reporting requirements Data Acquisition and Handling Systems (DAHS) can be provided. to provide fully automated calibrations of instruments, monitor calibration gas supplies and provide remote access and diagnostics.
