Wind Sensor

Wind speed & direction sensor for detecting wind speed & direction

What is an anemometer/wind sensor? An anemometer is an instrument that measures the air velocity. The main applications of wind sensor are in the field of meteorology and industrial applications such as in wind turbine business or high-rise crane safety monitoring. Wind speed sensor & wind direction sensor are used for wind speed and direction measurement. For the measurement of wind speed and wind direction, several principles may be used, as described in the WMO ‘Guide to Meteorological Instruments and Methods of Observations.

RIKA offers a wide range of wind speed and direction sensor & wind sensors with wind cup principle, ultrasonic principle or hotline principle, they are designed to be used within the hardest environmental conditions such as harsh marine environments and high accuracy EPA requirements. There are diverse types of anemometers like cup anemometer, vane anemometer, etc and among which that the wind cup anemometer is the most commonly used in meteorological stations. Our products are popular with customers globally.

Radiation Sensor

Pyranometer is an instrument used to measure the power of sunlight and heat. It is mainly used in the meteorological field. Solar radiation is identified by a solar intensity meter placed on a plane.

Types of pyranometer

We offer two types of solar radiation sensors: silicon-cell and thermopile pyranometers, both types are now ISO 9060:2018 Class C rated (previously known as a second class). Silicon-cell solar radiation sensor model is excellent for applications that do not require high accuracy and with a limited budget. It is with faster response time and a more competitive price.

But the solar pyranometer has higher errors under cloudy conditions. Our new cost-effective thermopile pyranometers feature a blackbody thermopile detector that provides a much broader and more uniform spectral response for better performance in all atmospheric conditions.

Applications of pyranometer

Illuminance sensor for solar radiation measurement is widely used for shortwave radiation measurement in agricultural, ecological, and hydrological weather, and optimizing photovoltaic systems

Ambient Sensor

Ambient sensor to detect atmospheric temperature, humidity & pressure

Ambient instruments and equipment traditionally used for atmospheric environmental quality monitoring are generally large-scale analytical instruments. The equipment is cumbersome and expensive, which is not conducive to the wide deployment of monitoring points, thus restricting the effective monitoring and treatment of the atmospheric environment.

The ambient sensor effectively solves the problems of existing analytical instruments. Atmospheric environmental monitoring sensors include air temperature, humidity, air pressure, dust, visibility, CO2, CO, SO2, O3, NH3 and other sensors, which are widely used in industrial and agricultural production and air quality monitoring.

Rain Gauge

Tipping bucket rainfall sensor is an instrument for testing rainfall

Rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually 1m2) and thus measuring rainfall amount. One millimeter of measured precipitation is the equivalent of one liter of rainfall per meter squared.

We offer tipping bucket rain gauges, radar rain gauges, rain sensor switches and evaporation sensors, all of which are used in hydro meteorological monitoring and agriculture. Rainfall monitoring is very important in wide range of fields like meteorology, hydrology, agriculture, forestry, field monitoring stations, and other industries, which enables people to prepare in advance. So we can imagine the importance of rain gauge. There are various types of rain gauges such as wireless rain gauges, tipping bucket rain gauges, automatic rain gauge station, etc.

Soil Sensor

Soil moisture & temperature sensor

Sensors that detect soil conditions have become an important tool for modern farmers in crop production. The benefits of soil sensors are obvious. There are different types of soil sensors, such as soil moisture sensors, soil temperature sensors, soil EC sensors, soil PH sensors, 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.

Due to differences in electrical resistance or electrical conductivity, information on soil moisture and soil particle composition can be clearly reflected, as well as intuitive conclusions on density, pH, salinity/conductivity, and temperature. Through the network construction on the farm, the real-time parameters collected by the soil sensor are transmitted to the computer mainframe and connected with the system installed on the machine to realize automatic control spraying of fertilizer and pesticides.

Data Logger

The data logger of the automatic weather station

Data logger that provides measurement and control for a wide variety of applications. Data loggers are an essential component in data acquisition systems. They can scan a wide variety of measurement sensors, perform programmed calculations, convert the data to other units of measurement, and store the data in memory.

The Data recorder’s reliability and ruggedness make it an excellent choice for remote environmental applications, including weather stations, mesonet systems, wind profiling, air quality monitoring, hydrological systems, water quality monitoring, and hydro-meteorological stations. The weather station data logger with data acquisition, storage, transmission and management, and other functions, is the core component of the automatic weather station. Automotive wireless temperature and humidity data logger place an important role in the weather monitoring system.

Water level sensors

Level sensors or water level switches detect the level of liquids, other fluids, and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface in tanks and process systems. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak. The substance to be measured can be inside a container or can be in its natural form (e.g., a river or a lake). Continuous level sensors measure levels within a specified range and determine the exact amount of substance in a certain place.

There are various kinds of water level sensors, such as pressure transducers, bubblers, shaft encoders, ultrasonic sensors, capacitance sensing, liquid float switch, bubbler sensor, etc. Level transmitter/liquid level sensor is one of the very important sensors and plays a very important role in a variety of consumer/ industrial applications. As with other types of sensors, water level probes are available or can be designed using a variety of sensing principles.
