Continuous Temperature Monitoring System Protects Life Science Products
By: CAS DataLoggers
A hospital required a continuous temperature monitoring system in order to measure and record the temperature of 50 freezers storing temperature-
The hospital's IT department also had a key requirement that they should be able to monitor data using just a single interface, so this necessitated a network setup. Users also needed alarm capability in case the temperature of any freezer should fall outside a specific range. To meet all these needs, the hospital found the ideal solution using dataTaker Data Loggers (https://www.dataloggerinc.com/
Three separate dataTaker DT80 units, one installed on each floor, now measure freezer temperatures both directly and via RS485 Modbus ADC devices. The DT80s are networked via Modbus TCP/IP and can be monitored through a web browser.

1. A cost-effective data logger expandable to 100 channels, 200 isolated or 300 single-ended analog inputs.
2. Built-in web and FTP server allows users to remotely access logged data, configuration and diagnostics.
3. Modbus slave and master functionality allows connection to Modbus sensors and devices and to SCADA systems.
4. Smart serial sensor channels capable of interfacing to RS232, RS485 and RS422 sensors and devices.
5. Rugged design and construction provides reliable operation under extreme conditions.
6. Includes USB memory stick support for easy data and program transfer.

The dataTaker units are connected to the hospital's existing LAN via Ethernet cables. This provides the physical connection for a Modbus TCP/IP network. One of the three DT80 dataloggers acts as a Modbus master, requesting and collecting data from the other two loggers and storing this data in its large internal memory of 10 million data points.
Even though the loggers are using Ethernet for Modbus (https://en.wikipedia.org/
Using this network topology, it's also possible to save each data point to all of the data loggers for backup purposes. If the hospital needs offsite backup, then the DT80 data loggers can be configured to automatically transfer data to a remote FTP server.
