Premium capacitance level sensor manufacturer and supplier today

Top capacitance level transmitter factory with Rika’s capacitive level gauge can measure the level of highly corrosive media, measure the level of high-temperature media, and measure the level of sealed containers, regardless of the viscosity, density, and working pressure of the media. The structure is simple, without any movable or elastic components, so the reliability is extremely high and the maintenance is minimal. Under normal circumstances, it is not necessary to carry out regular large, medium and small maintenance. It is suitable for liquid level measurement of high-temperature and high-pressure vessels, and the measured value is not affected by the temperature, specific gravity of the liquid being measured, and the shape and pressure of the vessel. Especially suitable for the measurement of acid, alkali and other strong corrosive liquids. Find extra details at capacitive level measurement.

Sensors that detect soil conditions have become an important tool for modern farmers in crop production. The benefits of soil sensor are obvious. There are different types of soil sensors, such as soil moisture sensor, soil temperature sensor, soil EC sensor, soil PH sensor, etc. The reason why need to measure soil moisture is that soil moisture plays an important role in the growth and development of plants. Soil temperature is often an important factor, especially in agriculture and land handling of organic wastes, because the growth of biological systems is affected by soil temperature. So soil temperature measurement is also important.

The whole structure of the rain gauge is made of metal parts without rust, the inner wall should be smooth and round, the edge of the water bearing device should be free of burr or bruit and other defects, the shape is beautiful and elegant, the weather resistance is good, and the service life is longer. The shell of a common rain gauge is a metal cylinder, divided into two sections. The upper section is a water funnel with a diameter of 20 centimeters. In order to prevent rain splashing and maintain the area and shape of the container mouth, the mouth of the cylinder is made of hard copper with a blade shaped like straight inside and oblique outside. Place a water bottle in the lower section cylinder to collect rainwater. To measure, pour rainwater into a special rain cup to read the precipitation in millimeters. In the snowfall season, the storage bottle is taken out and replaced with a cylinder without funnel. The snowflakes can be collected directly in the rain-measuring cylinder and read after the snow melts. The snow can also be weighed and converted into millimeters according to the area of the cylinder.
