Compact data logger for temperature measurement and reports exceeded limit values
Challenge
The motors and generators of a submarine shall be permanently monitored to avoid overheating. For this, a data logger shall effect temperature measurements and send a signal through Modbus TCP to a PC on the bridge as soon as a temperature limit is exceeded. For reasons of space, the temperature measurement system must be compact. Furthermore it shall be resistant to the harsh environmental conditions and interferences on a military submarine.
Solution
For this task, the intelligent Ethernet system MSX-E3211 for temperature measurement was chosen. It converts autonomously the acquired signals that exceed the tolerance limit into a command to switch on the ventilation systems.
It takes thus load off the PC on the bridge. For data recording, the system comes with a 64 MB RAM onboard memory. The robust and compact system complies to the IP 65 degree of protection and is suited for an operating temperature from -40 °F/+185 °F (–40 C to +85 °C). Furthermore, it is resistant to vibrations, resonances and forces up to 20 G. Protective circuits ensure the interference resistance of the system. The MSX-E3211 is equipped with a Modbus TCP server for transferring the acquired data to the PC on the bridge.
Benefits
- IP 65 and extended temperature range
- Vibration tests (from 10 G to 20 G)
- Compact
- Implemented Modbus TCP Server
