From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications.

Supplementary description

WS500-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, air pressure, wind direction and wind speed. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Ultrasonic sensor technology is used to take wind measurements. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS One external temperature or rain sensor is connectable.

Special features

  • Aspirated temperature/humidity measurement
  • Open communication protocol:
  • UMB-Binary
  • SDI-12
  • Analoge outputs in combination with 8160.UDAC
  • Third-Party-Rain gauge sensors are compatible: 0.1mm, 0.2mm, 0.5mm, 1mm heated and unheated
