An evaporation sensor is a device used to measure the amount of evaporation in a liquid or gas. It determines the amount of evaporation by monitoring the rate at which the vapor exits the surface of the liquid or gas. The sensor typically consists of a vessel containing a sample of the liquid or gas and a hole connected to the outside world that provides accurate evaporation data by measuring the flow or mass change of the vapor in the hole.
Characteristics of Evaporation Sensors
High precision: adopting advanced technology, it can monitor and record the change of evaporation in real time, and the high precision measurement makes it widely used in scientific research and industrial production.
Reliable: mostly adopts corrosion-resistant materials, can run stably for a long time under the bad environment, has good durability and anti-interference, suitable for a variety of application fields.
Easy to install and maintain: simple structure, generally only need to fix the sensor on the measured liquid or gas samples, and the corresponding calibration can start measurement.
Real-time monitoring: real-time evaporation data can be provided to help users grasp the volatile state of the measured liquid or gas in a timely manner, and then adjust and control accordingly.
Evaporation sensor performance parameters
Detection range: the range of evaporation that can be detected, generally expressed in terms of the mass or volume of evaporation per unit time.
Accuracy: the error between the measurement result and the actual value, generally expressed as a percentage or absolute error.
Response time: the time from receiving the input signal to stabilizing the output result, a shorter response time can provide more timely data feedback.
Temperature range: the ambient temperature at which the sensor can operate normally, exceeding this range may result in inaccurate measurement results or equipment damage.
Protection level: sensor enclosure protection level, usually expressed in IP standards, the standard consists of two numbers, the first number indicates the protection level of solid objects, the second number indicates the protection level of liquids.
Evaporation sensor working principle
Part of the evaporation sensor applies the principle of pressure measurement, through the high-precision weighing principle to measure the weight change of the liquid in the evaporation dish, and then calculate the height of the liquid surface, so as to measure the amount of evaporation, the measurement is more accurate, the data is more scientific.
Application areas of evaporation sensor
Meteorological observation: can be used to measure the water vapor content in the atmosphere, and then predict the precipitation and humidity changes.
Agriculture: for example, in the field of agricultural Internet of Things, hydro meteorology, the water surface evaporation of simple measurements, in the construction of high-standard farmland, intelligent agriculture (such as the four conditions of monitoring, intelligent greenhouses, intelligent farmland and other fields) also have applications.
Industrial production: for monitoring and controlling humidity and temperature in the environment, etc.
Scientific research: to provide accurate evaporation data for related research.
Plant Cultivation, Seed Cultivation, Agriculture and Forestry, Geological Survey: It is applicable to the relevant measurement work in the fields of plant cultivation, seed cultivation, agriculture and forestry, geological survey and so on.
