Automated Data Logging Reduces Manual Errors

 

Application Requirements

Humans make errors…it is a well-known fact.

 

Accuracy is critical in any manufacturing process including heat treat oven temperature monitoring. Reducing recording errors, data entry errors, and labor costs while increasing accuracy and quality of data in order to provide reporting to end customers is a recent application requirement presented to CAS Data Loggers.

Data Logging Solution

CAS Data Loggers recently converted a manufacturer's manual data collection process to automation. The customer has multiple, stationary heat treating ovens. Previous procedures required an employee to periodically read temperature values from controller displays and manually record them on paper forms.

 

dataTaker DT85 data loggers were installed using repeated signals from the existing temperature controllers as inputs. Process temperature data is now recorded without the need for human intervention. Each data logger is connected to the plant LAN via Ethernet so data can be automatically pushed via FTP to a local server for historical archiving. Data is available via the DT85's internal web server for ad hoc monitoring of the oven temperatures throughout the plant.

 

Quality engineers can access the logger's internal web server from any internet location for remote monitoring. If a power disruption occurs, the digital temperature record allows engineers to determine where the cycle was interrupted therefore allowing them to restart without repeating or missing process steps. This reduces wasted energy and scrap while increasing product quality.
