Table 1. Ordering option 1: measurement range
Sensor type Measurement range
1 WMT701 up to 40 m/s
2 WMT702 up to 65 m/s
3 WMT703 up to 75 m/s
4 WMT704 up to 90 m/s
A WMT701 up to 40 m/s + accredited wind calibration
B WMT702 up to 65 m/s + accredited wind calibration
C WMT703 up to 75 m/s + accredited wind calibration
D WMT704 up to 90 m/s + accredited wind calibration

Accredited wind calibration is according to the Measnet procedure.

Table 2. Ordering option 2: temperature range
Option Temperature range
A -10 ... +60 °C
B -40 ... +60 °C
C -55 ... +70 °C
The temperature range is not connected to heating in any way. If you operate in a demanding environment where ice accumulation is expected, Vaisala recommends using a heated sensor.
Table 3. Ordering option 3: heating
Option Heating
1 Non-heated
2 Heated transducers (min. 30 W power supply is needed)
3 Heated transducers and arms (min. 150 W needed)
4 Heated transducers, arms, and body (min. 250 W needed)
Power consumption requirement depends on the selected heating option.
Vaisala recommends using heated versions of WMT700 in environmental conditions where snow and ice build-up is possible. Full sensor heating is best suited for the most demanding environments.
Table 4. Ordering option 4: digital communication interface
Option Hardware interface
A RS-485 isolated (1 pair)
