Abstract

The invention discloses an engine temperature sensor test system and a test method, and the design concept of the engine temperature sensor test system is that the type characteristics and performance parameters of a temperature sensor are combined; and an environment temperature box, a controller, a data acquisition box and a data conversion and industrial control mechanism are utilized to establish a system architecture which is simple in measurement mode, high in measurement precision and capable of realizing performance test of one or more temperature sensors and a corresponding test method. The system is simple in installation and operation, short in detection time and high in measurement precision, meets the rapid detection and test requirements in the research and development, production and manufacturing processes, can achieve the unified test of the high and low temperature performance, durability and the like of a plurality of engine temperature sensors, and especially does not need to be matched with an engine pedestal or a whole vehicle. Compared with an existing engine temperature sensor test scheme, the test cost is greatly reduced on the basis of ensuring that the test effect is comprehensive and stable.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine temperature sensor testing system and testing method. Background technique [0002] Sensors are an important part of the engine. Each engine is equipped with a large number of sensors and a variety of sensors. The quality of the sensors will directly affect the performance of the engine and the achievement of emission targets. The temperature sensor is usually made of temperature-related metals, semiconductors and other materials. The basic electrical characteristic of the commonly used thermistor is to change the resistance with the change of temperature, and it will also pass through the thermistor with the surrounding temperature or current. resistance resulting in self-heating changes. In the engine field, NTC (negative temperature coefficient) thermistor temperature sensors and positive temperature coefficient resistance temperature sensors are commonly used, such...
