piezoelectric rain sensor CG-62 piezoelectric rain transmitter helps rainfall monitoring
product description
The sensor consists of an upper cover, a shell and a lower cover. There are piezoelectric sheets and circuit boards inside the shell, which can be fixed on a column with an outer diameter of 50mm. The sensor uses the impact measurement principle to measure the weight of individual raindrops and then calculate the amount of rainfall. During the falling process, the raindrop is affected by the weight of the raindrop and air resistance. When it reaches the ground, its speed is constant. According to P=mv, the weight of the raindrop can be obtained by measuring the impact, and then the continuous rainfall can be obtained.Features
◆Solid state integrated design◆Use the impact measurement principle to measure the weight of a single raindrop and then calculate the rainfall amount◆No mechanical accessories, no exposed parts◆Wide measuring range, low power consumption, anti-external interference ability◆Smallly affected by weather changes, monitoring rainfall duration to the second level◆Low maintenance requirements, the raindrop contact surface is an arc-shaped design structure, and does not store rainwater◆With automatic horizontal calibration function after installation, no on-site calibration is required◆Compact size, easy to carry, disassemble and installWorking and storage conditions
Working temperature: -40～85°C Working humidity: 0～100RHStorage temperature: -40～125°C Storage humidity:<80% (no condensation)Technical Parameters
Measurement parametersRainfall measurement:Rain intensity range: 0.3～10mm/minResolution: 0.01mmMeasurement accuracy: ±4% (daily cumulative rainfall)Refresh interval: 5sCumulative rainfall: Total rainfall since power onCurrent rainfall: After the rain stops, the data will be kept until the next rainfall automatically starts from zero.The duration of rainfall in this field: the unit is 5s. For example, when the value is 12, it means that it has rained for 60s.Rainfall in the past 1 minute: Smoothed recursive value in the past 1 minuteRainfall in the past 10 minutes: Smoothed recursive value in the past 10 minutesPeak minute rainfall of this field: Peak minute rainfall of this fieldOptional parametersAir temperature: -40～85℃ Resolution: 0.1℃ Measurement accuracy: ±0.3℃Relative humidity: 0～100%RH Resolution: 0.1%RH Measurement accuracy: ±3%RHAtmospheric pressure: 300～1100hPa Resolution: 0.1hPa Measurement accuracy: ±0.4hPaOther parametersData transmission method: RS485, LTE CAT-1, 4G, LoRa, NB-IoT can be customized, supporting positioning functionPower supply range: Mains power using adapter 5~24VDC or built-in lithium battery + solar power supplyProtection level: IP67
Scope of application
It is widely used in meteorological environment monitoring, hydrology and water conservancy comprehensive monitoring stations, traffic and road monitoring, agriculture and forestry, wind power generation, etc. to remotely measure precipitation amount, precipitation intensity, and precipitation start and end time. It is used for automatic hydrological forecasting and reporting systems, automatic field forecasting and reporting stations, etc. for the purposes of flood control, water supply dispatching, and power station and reservoir water regime management.Two installation methods
1. Installation on 76mm pole
The supporting semicircle cross arm is suitable for a 2-inch and a half vertical pole (outer diameter 76mm). The sensor is installed using 2 M3*10 cross round head screws with a hole spacing of 64mm.2. Install on the top of the 50mm pole
It is equipped with a vertical pole with an outer diameter of 50mm (wall thickness not greater than 3mm). An M6 threaded hole is opened on the side of the pole. The center of the hole is 8mm from the top of the pole. Use M6*15 cross round head screws to fix the sensor.Product Size
