ES-EVA-30 Evaporation Sensor

ES-EVA-30 evaporation sensor is an instrument developed by our company to observe water surface evaporation. The product adopts a double-layer stainless steel structure design, which can prevent evaporation errors caused by direct sunlight, and the measurement accuracy is more accurate. The whole product is made of 304 stainless steel, with exquisite appearance and corrosion resistance, which can effectively guarantee the service life of the sensor. Using digital sensors, it has the characteristics of high measurement accuracy, wide range, high sensitivity, no temperature drift, time drift, and long-term stable performance. The equipment adopts standard ModBus-RTU 485 signal output.

ES-EVA-30 evaporation sensor adopts the pressure measurement principle, measures the weight change of the liquid in the evaporating dish by the weighing principle, and then calculates the liquid level to obtain the evaporation amount, which is more accurate and the data is more scientific; it is not affected by the freezing of the liquid, and overcomes the shortcomings of inaccurate measurement when freezing, easy damage to the sensor when there is no water, and low measurement accuracy when using the ultrasonic principle to measure the liquid level. The product is suitable for meteorological observation, plant cultivation, seed cultivation, agriculture and forestry, geological survey, scientific research and other fields. It can be used in conjunction with automatic water adding devices, data acquisition and transmission devices, etc. to realize automatic monitoring of the evaporation process, and can also be used in combination with data acquisition and storage devices (recorders) to realize automatic storage of evaporation data. It can also be used in conjunction with rainfall sensors, data acquisition and transmission devices, etc. to realize automatic observation and remote transmission of evaporation and rainfall processes. In addition, it can be used as a component of rainfall stations, evaporation stations, meteorological stations, environmental monitoring stations and other equipment to observe “water surface evaporation”, one of the meteorological or environmental parameters.
