In relation to exhaust gas measurement with a thermocouple, use of an amplifier which gives a mA-signal out is preferred. Why is this done?
This depends on the length of the compensation-cable.
The output signal from a thermocouple is at mV level,and can not be transferred over any long distance without loss of signal, giving a poor accuracy and poor noise immunity.
The signal out from the thermocouple is also mA, but have to be amplified in order to give a good signal to the alarm system.

There is an almost universal use of standard height pallets.
It is easier to construct vessels with shallow decks.
The increased number of container vessels has reduced the tendency to carry general cargo outbound from Europe or North America to Australia and New Zealand on reefer vessels.
