Vaisala instruments and systems are used the world over by organizations that need to measure the environment with great accuracy and consistency. The aim of the Integrator Segment Sales Unit is to build relationships with key meteorological integrators, and as a their partner in business, provide them with instruments, systems and solutions. We understand meteorological integrators to be companies that incorporate Vaisala's products into their own system or solution offering. Meteorological integrators may have customers in many sectors such as meteorology, hydrology, defence, aviation, oceanography, marine and the environmental sector.

Vaisala offers products that include meteorological instruments such as humidity, temperature and pressure transmitters, ceilometers, present weather detectors, anemometers, precipitation, hydrometeorological and visibility sensors. Other products include for example wind profilers, radiosondes, automatic weather stations, thunderstorm sensors, weather radar and Sigmet's weather radar components.

Technology development

The sensor or the sensing element is crucial for the performance and stability of every measurement instrument. For years, Vaisala has developed a range of patented sensor technologies that are unique to Vaisala instruments. These technologies include thin film and silicon microsensors, ultrasonics, optics and techniques for measuring absorption and atmospheric scattering. Our efforts in improving and developing new types of sensing technology are well known by meteorologists and industrial users.

Vaisala is an international technology company that has grown successfully since its founding in 1936. Headquartered in Finland and listed on the Helsinki Stock Exchanges, Vaisala develops and manufactures electronic measurement systems and instruments for diverse applications covering meteorology, the environmental sciences, air and road traffic safety and general industry. Vaisala employs over 1000 professionals worldwide. Annually, over 95% of revenue is earned outside Finland.

Upgraded Wind Sensor and Weather Transmitter from Vaisala

Vaisala has introduced new versions of the ultrasonic wind sensor, the Vaisala WINDCAP® Ultrasonic Wind Sensor WMT52, and the weather transmitter, the Vaisala Weather Transmitter WXT520. Both instruments use ultrasonic technology for measuring horizontal wind speed and direction. In addition the WXT520 measures liquid precipitation, barometric pressure, temperature and relative humidity - all in one instrument.

The maintenance-free ultrasonic Vaisala WINDCAP® Sensor, in both the WMT52 and WXT520, ensures accurate readings from any horizontal wind direction avoiding blind angles and corrupted readings. In the WXT520 the Vaisala RAINCAP® sensor measures precipitation, providing data on accumulated rainfall, rain intensity and duration, all in real time.

Both the WXT520 and WMT52 have a housing and mounting kit that is water resistant with an IP66 classification . The transmitters have new interface cards and they are ROHS compliant.

A number of optional features are offered, such as, heating, a bird-deterrent spike kit, a USBservice connector, and a new surge protector. The wind and rain sensors can be equipped with heating to improve the availability of correct measurement data also in severe weather conditions. The USB connection facilitates the connection to a PC as a service connector, or when the PC is used as a terminal device, this is an additional option, and does not replace the serial connector option. The Vaisala Surge Protector WSP152 is designed to protect the host PC against surges that may be entering through the USB port.

New LAN and WLAN options available

Vaisala now offers new computer connectivity options:
• for Vaisala humidity, dewpoint, moisture in oil and barometric pressure transmitters
• which allow for the connection of transmitters to Ethernet or Local Area Networks (LAN) and Wireless Local Area Networks (WLAN)
• which reduces the amount of cabling, for convenience and cost saving
