Description

MicroVen-ALARM is a system designed to continuously monitor the anemometric data by alerting the available personnel in situations of strong wind. The datalogger acquires, processes, stores (black box function) and transmits the anemometric data; it has 2 adjustable thresholds for the wind speed and 2 for the wind direction (understood as sector start and end). When an overcoming  occurs, the datalogger activates a relay contact.

MicroVEN-Alarm has the main following features:

  • Display of wind speed and direction 
  • Black box: backup storage of anemometric measures and silence events on SD Card
  • Management of 2 alarm levels:
    • Level 1 (low): warning or pre-alert condition
    • Level 2 (high): alarm or critical condition 
  • Temporary silence of alarms and relays check
  • Hysteresis control on the anemometric measure to prevent  false alarms caused by temporary wind gusts

 

 

ADVANTAGES 

  • Easy mounting, using and user’s control and minimum required maintenance
  • Very high accuracy of measurement, reliability over time, setting of main parameters 
  • Data storage on SD Card with anti-manipulation protection system
  • Sensors and dataloggers compliant to WMO - Annex 8 guidelines (World Meteorological Organization) 
  • Professional Anemometer Measnet or Accredia certifiable, also in anti-icing heated version
  • Conformity to LCPC Setra 2000 Guidelines (construction sites and roads)
  • Fully Italian Technology
