Product description

Parameters

Technical indicators

- working principle:

Ultrasound

-Application industry:

Automatic weather station with weather service;

Automatic weather stations on airports, docks, and ships;

Wind power control;

Weather monitoring of road traffic control system;

Avalanche and flood warning for mountain weather stations;

Hydrometeorological Observatory

-Instrument features:

Built-in data preprocessing, universal interface and selectable output protocol, compatible with OTT data recorder, hydrometeorological data recorder and PLS system;

Maintenance-free operation, using ultrasonic technology for measurement, no wear of moving parts, no need for re-calibration;

Applicable to all climatic zones, and also to solar automatic weather stations;

The heating sensor has a powerful integrated heating function. In the case of frost, the heater can be turned on to ensure that it performs anti-freezing operations at extremely low temperatures (-40 °) and freezing;

Anti-vibration, seawater corrosion resistance, suitable for coastal areas;

Successfully passed the test and certification under extreme environmental conditions (temperature, humidity, electromagnetic compatibility, vibration, salt spray, freezing).
