Capteur de niveau d'eau Capteur de niveau de liquide analogique 0-5v/4-20mA/rs485 pour fermes

Capteur de niveau d'eau Présentation du produit :

Le capteur de niveau d'eau utilise une puce sensible à la pression en silicium à diffusion de haute précision et de haute stabilité et, grâce à un circuit d'amplification de haute fiabilité, convertit le signal de niveau d'eau du liquide à mesurer en signaux tels que le courant et la tension, qui sont disponibles pour les utilisateurs. 

Ce produit peut être largement utilisé dans la mesure et le contrôle du niveau d'eau dans le domaine industriel, le sol, les rizières, la mesure et la surveillance hydrologiques, les navires et les systèmes de navigation.

Capteur de niveau d'eau Entretien de l'instrument :

1. Requirements for water use of the water level device: water that represents the local natural water body (river, river, lake) should be used as much as possible. In areas where it is difficult to obtain natural water, drinking water (well water, tap water) can also be used; the water in the device To keep clean, there is no floating objects on the water surface, no small insects and suspended dirt in the water, no moss, no significant change in water color; generally change the water once a month. The water level bucket should be cleaned when the water level gauge is changed, and the temperature of the replaced water should be close to the temperature of the original water;

2. Stop observations in areas with a long freezing period in winter, and use a small water level gauge to observe the water level on the ice surface throughout the freezing period. Drain the water in the large water level gauge to avoid freezing;

3. Before and after the flood season (for long-term stable frozen areas, before starting to use and after stopping use), check the leakage of the water level device once a year; if any problems are found, they should be dealt with;

4. Regularly check the installation of the water level gauge. If it is found that the height is inaccurate or not level, it should be corrected in time;

5. The water surface in the water ring should be close to the water surface in the water level bucket.

Today, farms are large and manual irrigation can take a lot of time and be less efficient, while labor costs are high.

Automatic irrigation technology can reduce labor costs by 50% instead of manual irrigation. Automatic irrigation eliminates the need for irrigation ditches and borders in the field, making better use of the arable land than surface irrigation and improving land use, typically increasing the cultivated area by 7-10%. In addition, automatic irrigation will reduce the damage to the soil, which will help to increase the yield.

In order to achieve better control of farm irrigation and save more water resources, we need to design an effective remote controller for automatic farm irrigation.

The application of level sensors in the farm based growth intelligence automatic irrigation scheme.

The required sensors and the network are arranged on the farm, and the sensors are used to detect the plant soil and climate data.

In agricultural irrigation systems, the main role of the level sensor is to act as a water level control. The level sensor is usually located somewhere on the top and against the lower part of the tank. The level sensor automatically detects the depth of the water layer and transmits the collected data to the intelligent irrigation control system in real time through a wireless transmission device.

Une fois le diagnostic effectué, la commande est transmise au dispositif de contrôle d'irrigation du champ, qui remplit automatiquement la rizière d'eau. Lorsque le niveau d'eau baisse, la valeur de sortie du capteur de niveau change, ce qui déclenche l'alarme du système d'irrigation et coupe l'alimentation du circuit de travail, économisant ainsi l'eau d'irrigation et optimisant son utilisation.
