All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
When the engine is subjected to bench test, the running engine needs to be cooled by using cooling liquid in real time, and the cooling liquid can be deteriorated or enter impurities due to high temperature in the long-term use process. Therefore, the physical and chemical analysis of the components of the cooling liquid is required to be carried out regularly during the bench test, so that the cooling liquid is ensured not to deteriorate in the use process.
At present, in an engine bench test, a manner of periodically pumping cooling liquid to detect whether the cooling liquid is deteriorated is generally adopted for physicochemical analysis of components of the cooling liquid; the method of periodically extracting the cooling liquid for component analysis is adopted, certain hysteresis exists, the change of the cooling liquid components in the expansion water tank cannot be monitored in real time, the bottom of the expansion water tank is sampled when the engine oil is sampled, if the engine oil enters the cooling liquid, the engine oil floats on the surface of the cooling liquid, and the polluted part of the surface of the cooling liquid in the expansion water tank is not easy to detect. In the actual detection process, the operation of regularly pumping the cooling liquid in the expansion tank for physical and chemical analysis is also troublesome.

The conductivity sensor 3, upon detecting the conductivity of the cooling liquid, converts the conductivity into the form of an electrical signal and transmits it to the data processing unit 2. For example, when the oil enters the coolant, the oil floats on the surface of the coolant, and the conductivity sensor 3 detects that the oil has a conductivity of about 10000ps/m, whereas the normal coolant has a conductivity of about 5×10 8 ps/m, the conductivity of the two is very different, so that the change of the composition of the cooling liquid can be judged according to the change of the conductivity.
