Wind Direction (JY-WS161B)

  • Type : Vane
  • Measuring Range : 0 ~ 360°
  • Threshold : 0.3m/s Below
  • Resolution : ± 2.8 °
  • Accuracy : ± 3 °
  • Operating Temperature : 40 ~ +80 ℃
Description

This sensor is designed to operate properly under any weather conditions. The sensor consists of the counter-balanced, light wind vane and highly accurate, low threshold gray code encoder. The wind direction is measured in the built-in Micro-processor and measured value is output in terms of the digital.

Wind Speed (JY-WS161B)

  • Type : 3-cup Anemometer
  • Measuring Range : 0 ~ 75 m/s (0~145 knots)
  • Threshold : 0.3m/s Below
  • Resolution : 0.1 m/s
  • Accuracy : ±0.15 m/s
  • Distance Constant : 4m Below ?
  • Operating Temperature : 40 ~ +80 ℃
Description

The wind speed sensor is designed to be responsive even to low wind speed with quick responding time. Followed by the rotation of 3 cup, the 60-hole photo chopper, connected to the lower part of bearing, rotates. In accordance with the number of this rotation, a photo diode produces the frequency in proportion to wind speed. The light and chemically etched rotor of a sensor rotates along with cup set. As the rotor rotates, the photo chopper diode interrupts light. The photo diode drives turn a photo electric converter, which outputs in its turn rectangular wave.

Temperature (JY100829)

  • Type : Platinum resistance (PT-100)
  • Measuring Range : -50 ~ +70 ℃, -40 ~ +60 ℃ (for Air)
  • Resolution :0.1 ℃
  • Accuracy : ±0.1 ℃
  • Responding Time : 45 sec (63.2% step change) ?
  • Model : JY1000829(Air), JY1000831(Ground), JY1000832(Soil), JY10000832(Grass Height)
Description

The sensor is designed in compliance with the principle that electric resistance value of a pure metal changes in accordance with fluctuation of temperature.
The sensor is excellent in linearity and stability and in compensating for turn rectangular wave. resistance value by using the 4-line type, in which corrosion-free platinum is used.
The sensor is designed to be easily adaptable for different use of sensor, such as measuring air temperature, ground temperature, soil temperature and grass-height temperature respectively.

Relative Humidity (JY-RHD200)

  • Measuring Time : 0 ~ 100 %RH)
  • Operating Temperature : -50 ~ +80 ℃
  • Temperature Dependance : ±0.05%RH/ ℃
  • Responding Time : 20sec with filter
  • Accuracy (at 20℃) : 20 ~ 100 %RH : ± 3 %RH, 0 ~ 20 %RH : ± 5 %RH?
Description

The sensor is designed to measure humidity in the air making use of thin-film type, and relative humidity and temperature are measured . Both the humidity and temperature sensors are located At the end of the probe, and are protected by the thin membrane filter.
The voltage is output in terms of difference type pro-portional to humidity.

Rain Gauge (JY100097-2)

  • Type : Tipping Bucket
  • Measuring Range : 0 ~ 700 mm/h
  • Operating Humidity : 0~100%, Temperature: 0℃ ~ 30℃
  • Resolution : 0.5 mm
  • Accuracy : ± 0.5mm ( 0 ~ 20 mm/h ), ± 3% ( > 20 mm/h )
  • Meterial : Rim - Hard coated brass, Body - Stainless Steel 27
Description

JY100097-2 Tipping Bucket Rain Gauge and Precision Weather Instrument for measuring rainfall volume.
The gauge is designed in the form of funnel covered with 200 mm-diameter screen, when rainwater enter the funnel, it flows into the triangular tipping bucket, and when the water reached 0.5mm, it is tipped, which activates the closed lead switch, transmitting the signal to the Data Logger.
Overflown water, when the bucket tipped, is drained through dump hall to the ground. The heater with 250W is designed to activate when temperature goes down below 5℃, and to measure indirectly the snow accumulation, melting the snow into the rain.

Atmospheric Pressure (JYB400)

  • Measuring Time : 600 to 1100 hPa
  • Resolution : 0.1 hPa
  • Accuracy : -±0.5 hPa, 25 ℃
  • Operating Temperature : -40 ~ +50 ℃
  • Stability : ±0.2 hPa/year
  • Response Time : 1 sec
Description

The propose JYB200 model atmospheric Pressure sensor offers outstanding value to instrument builders requiring accurate and stable barometric measurements in real-world conditions.
The JYB200 uses proven silicon sensor technology with microprocessor-based signal compensation, eliminating the need to insulate or temperature-regulate the barometer. The JYB200 has a pressure range of 600 to 1100hPa.

Rainfall Detector (JY100097-3)

  • Type : Grid impedance
  • Detect : Rain
  • Input : DC 12V
  • Output : 'Low' or 'High'
Description

This sensor is designed to detect dew, rain and precipitation in the atmosphere making use of the principle of activating the electronic circuit of the sensor when moisture drops on the sensor from the upper air.
The sensor is of high accuracy and durability and made so as not to be interrupted by fog or mist with help of built-in heater.

Radiation Shield (JY10553)

  • Type : Naturally Aspirated Radiation Shield
  • Plate Material : ASA
  • Outside Diameter : 160mm
  • Overall Height : 260mm
Description

Radiation Shield JY10553 is a naturally aspirated shield ideal for most situations. The fan forced option is available where a more rapid response is required. The radiation shield JY10553 protects Temperature and Humidity Sensors from both solar radiation and precipitation by allowing free flow of air through the shield.
The Plate is highly UV resistant and it withstands long term exposure and it has thermal conductivity and the high luster white color reflects incident solar radiation.
