In device, volume is minimum, weight is the lightest.
This utility model uses Germany's import film platinum resistor element, measures temperature range width, and resistance is by mistake
Difference is little, is suitable for the temperature survey of precision.In severe and complex environment, it is possible to quickly respond inspection
Measuring point temperature, signal is accurate, and transmission is reliable, is monitored variations in temperature in real time by monitoring system, to protect
The safe operation of card vehicle.This utility model volume is little, lightweight, be easily installed.By fixing seat
Three installing hole 1c on 1b install within air-conditioning systems.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow ripe
The personage knowing technique will appreciate that content of the present utility model and implements according to this, can not limit with this
Make protection domain of the present utility model.All according to this utility model spirit made equivalence change or
Modify, all should contain within protection domain of the present utility model.
