Vaisala WXT530 Series Multi-Parameter Weather Transmitter

Vaisala WXT530 Series Weather Transmitter

The compact Vaisala WXT530 Series measures wind, precipitation, barometric pressure, air temperature and relative humidity in selectable combinations for industrial and environmental weather monitoring.

  • Choose one to six essential weather parameters
  • Ultrasonic wind and acoustic precipitation measurement
  • No moving parts and low maintenance requirements
  • Modbus RTU, SDI-12, ASCII and NMEA communication options

Vaisala WXT530 Compact Multi-Parameter Weather Transmitter

The Vaisala WXT530 Series is a compact family of solid-state weather transmitters for measuring wind speed, wind direction, liquid precipitation, barometric pressure, air temperature and relative humidity. Six model combinations allow users to purchase only the weather parameters required by the application.

Unlike a conventional automatic weather station assembled from several separate sensors, the WXT530 integrates the selected measurements into one lightweight instrument. Its solid-state design has no moving wind or rain-measurement parts, helping reduce mechanical wear, routine maintenance and installation complexity.

The fully equipped WXT536 measures all six parameters. Other models provide dedicated rain, wind, pressure-temperature-humidity, or combined measurement packages.

Why Choose the Vaisala WXT530 Series?

  • Selectable Measurement Package: Choose the WXT531, WXT532, WXT533, WXT534, WXT535 or WXT536 according to the parameters required.
  • Six Essential Weather Parameters: The complete WXT536 measures air pressure, air temperature, relative humidity, precipitation, wind speed and wind direction.
  • No Moving Parts: Ultrasonic wind and acoustic precipitation technologies avoid rotating cups, vanes and tipping mechanisms.
  • Low Maintenance: Solid-state sensors and a compact enclosure support dependable unattended operation.
  • Flexible Integration: Digital interfaces include RS-232, RS-485, RS-422 and SDI-12, with Modbus RTU, ASCII and NMEA protocol options.
  • Industrial Wind Output: The WXT532 can be configured with 0–20 mA or 4–20 mA outputs for wind speed and direction.
  • Expandable Weather Hub: WXT536 analog inputs can accept compatible external solar-radiation, temperature, voltage or tipping-bucket sensors.
  • Outdoor Protection: Rated IP65 without the mounting kit and IP66 when installed with the specified mounting kit.
  • Low Power Consumption: Suitable for remote and solar-powered installations when the complete power system is correctly designed.

WXT530 Model Selection

ModelPressure, Temperature and HumidityPrecipitationWindRecommended Use
WXT531 — Yes — Compact rain and hail measurement
WXT532 — — Yes Wind speed and wind direction
WXT533 — Yes Yes Wind and precipitation monitoring
WXT534 Yes — — Pressure, temperature and humidity monitoring
WXT535 Yes Yes — PTU and precipitation monitoring
WXT536 Yes Yes Yes Complete six-parameter weather monitoring

Selection guidance: Choose WXT532 when only wind speed and direction are required. Choose WXT536 for a complete compact weather station. WXT533 is suitable when wind and rain are needed without pressure, temperature and humidity, while WXT534 provides the PTU parameters without wind or precipitation.

Pressure, Temperature and Humidity Performance

ParameterRangeAccuracy
Barometric Pressure 500–1100 hPa ±0.5 hPa at 0 °C to +30 °C and 600–1100 hPa; ±1 hPa across the wider specified temperature range
Air Temperature -52 °C to +60 °C ±0.3 °C at +20 °C for the sensor element
Relative Humidity 0–100% RH ±3% RH from 0–90% RH; ±5% RH from 90–100% RH

The PTU module used for pressure, temperature and humidity is replaceable, simplifying scheduled maintenance of models equipped with these measurements.

Precipitation and Hail Measurement

The RAINCAP sensor detects the acoustic impact of individual raindrops on its stainless-steel surface. The transmitter calculates accumulated rainfall, current and peak intensity, rain-event duration and hail-related values without a conventional tipping bucket.

Rainfall Resolution 0.01 mm
Daily Accumulation Field Accuracy Better than 5%, weather dependent
Rain-Intensity Observation Range 0–200 mm/h; broader reporting with reduced accuracy
Rain-Intensity Resolution 0.1 mm/h
Rain Duration Resolution 10 seconds
Hail Detection Cumulative hits, current intensity, peak intensity and event duration
