Chapter 1 _________________________________________________________ General Information

			Documentation Conventions
			Throughout the manual, important safety considerations are
			highlighted as follows:
		WARNING	Warning alerts you to a serious hazard. If you do not read and follow
			instructions very carefully at this point, there is a risk of injury or even
			death.
		CAUTION	Caution warns you of a potential hazard. If you do not read and follow
			instructions carefully at this point, the product could be damaged or
			important data could be lost.
		NOTE	Note highlights important information on using the product.
	Safety
			Vaisala WINDCAP® Ultrasonic Wind Sensor WMT701,
			WMT702, or WMT703 delivered to you has been tested for safety
			and approved as shipped from the factory. Note the following
			precautions:
		WARNING	To protect personnel (and the wind sensor), a lightning rod must be
			installed with the tip at least one meter above WMT700. The rod must be
			properly grounded, compliant with all local applicable safety regulations.
			Do not install the wind sensor above the top of the lightning protection
			rod.
		WARNING	If ice or snow accumulates on WMT700 or the mast, it can fall and cause
			injury to persons below.
		WARNING	Some WMT700 product versions provide heating for transducers and/or
			array arms. To avoid injury, do not touch the heated parts of the wind
			sensor when the heating is enabled.

VAISALA________________________________________________________________________ 13

User's Guide ______________________________________________________________________

		WARNING	Make sure that you connect only de-energized wires.
		WARNING	Using a long cable between different units (sensors, transmitters, power
			supplies, and displays) can cause a lethal surge voltage, if a lightning
			strike occurs in the vicinity. Always apply proper grounding procedures
			and follow the requirements of the local Electrical Code.
		WARNING	Do not install WMT700 when there is a risk of thunderstorm or lightning
			activity in the area.
		CAUTION	Do not modify the unit. There are no user-serviceable parts inside.
			Improper modification can damage the product or lead to malfunction.
		CAUTION	When handling WMT700, do not rotate, pull, strike, bend, scrape or
			touch the transducers with sharp objects. Any impact on the wind sensor
			array may damage the device.
		CAUTION	The heating power supply wires of WMT700 are internally connected to
			each other. If the connection cable has two positive heating supply wires,
			both must be connected to each other. Leaving one terminal unconnected
			or connecting it to the ground may cause a WMT700 malfunction or a
			short circuit in the power supply.

Recycling

Recycle all applicable material.

Dispose of batteries and the unit according to statutory regulations.

Do not dispose of with regular household refuse.

CHAPTER 2

PRODUCT OVERVIEW

This chapter introduces the features, advantages, and product nomenclature of WMT700.

Introduction to WMT700

Vaisala WINDCAP® Ultrasonic Wind Sensor WMT700 measures wind speed and direction, and sends the measurement results to data acquisition systems. WMT700 forms part of the Vaisala weather measurement offering suitable for systems and standalone installations.

The WMT700 series consists of three product types with different measurement ranges: WMT701, WMT702, and WMT703. Additionally, you can select heating functions that shield the array and/or the transducers and the sensor body from ice and snow buildups in cold climates.

The WMT700 series wind sensors are based on the advanced, patented Vaisala WINDCAP® wind measurement technology that ensures accurate results in all wind directions. The effects of temperature, humidity, and pressure are also fully compensated.

Since the WMT700 series wind sensors have no moving parts, they are virtually maintenance-free. The performance of the sensors does not degrade with wear nor is it affected by natural contaminants such as salt, dust, or sand.

The WMT700 series wind sensors support a wide range of communication options. You can connect the wind sensors directly to a variety of data acquisition systems without additional converters or adapters.

VAISALA________________________________________________________________________ 17

User's Guide ______________________________________________________________________

WMT700 is configured at the factory according to the customer's order, and it is ready for operation directly after the installation. If required, the user also has a wide range of configuration options for the wind sensor and the measurement settings.

WMT700 can be equipped with accessories to tailor the instrument to match different user-specific needs. The accessories include a bird deterrent solution and a field-usable calibration verifier.
