A CAS Data Logger customer held to these requirements also wanted to monitor the data from multiple sites from a single, corporate location. dataTaker DT80 units were selected for the solution. Each DT80 could monitor up to 4 extruders.
A thermistor was installed to monitor the temperature of the food as it exited each machine. The data was recorded to satisfy regulatory requirements and show that the extrusion occurred at an appropriate temperature to prevent bacteria growth. Each machine was equipped with industrial I/O modules wired into the digital I/O of the data logger to monitor proper operation and to activate a diverter to redirect the food to a scrap container if the temperature fell below the acceptable threshold.
A program was written for the data logger to record the data at 1 minute intervals. Each machine was monitored independently to aid in data management. An alarm was configured to compare the measured temperature against the threshold and activate a digital output on the logger if the temperature fell below the acceptable temperature.
Data was stored to the internal memory of the data logger, then periodically transferred to a USB stick and archived on a separate server. The USB stick also allowed for easy programming changes and firmware updates without connecting to a PC.
Using this designed solution, the manufacturer has been capable of continuous documentation for their production process to ensure that all products that leave the facility are safe and meet all FDA standards.
