Description

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

Supplementary description

WS501-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, solar radiation, 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. The world renowned technology of Kipp Zonen CMP3 is integrated. 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:

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