Abstract

The invention discloses an evaporation sensor, and belongs to the technical field of sensors. The evaporation sensor comprises an evaporation sensor shell and an evaporation sensor, the evaporation sensor is fixedly arranged in the evaporation sensor shell, and the evaporation sensor comprises a liquid level detection module, a signal acquisition module, a CPU module, a signal output module, a power supply module and a data storage module. A soaking tank is arranged at the bottom of the evaporation sensor shell, a signal output plug is arranged at the top of the evaporation sensor shell, the signal output module adopts a standard RS-485 communication interface, the CPU module adopts a single chip microcomputer as a main controller, the evaporation sensor liquid level detection adopts an immersion liquid level detection mode to be matched with an evaporation dish for use, and the evaporation sensor is in threaded connection with the upper edge of the soaking tank through a fixing hole and is 7cm away from an opening of the evaporation dish. According to the evaporation sensor, automatic calculation of the evaporation capacity is achieved, manual checking is not needed, the overall structure of the evaporation sensor is simple, and high-precision and high-reliability automatic measurement of the water level is achieved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an evaporation sensor. Background technique [0002] At present, there are mainly three types of automatic measurement of evaporation: float level gauge measurement method, ultrasonic liquid level measurement method, weighing method, etc. [0003] There are two ways to measure the float level gauge: 1. Through the connecting pipe, the water level inside the evaporator is led to another still water bucket through the connecting pipe, and then the high-precision float water level gauge is used to measure the water level change in the still water bucket. There is a conversion of the surface area of ​​the evaporated water in the process, and the change of the water body inside the still water bucket is not easy to calculate. Moreover, the connecting pipe between the evaporator and the still water bucket needs to break the ground, and the construction is difficult. If the connecting ...
