PCE-WV A 4-20mA (HEATED)

PCE-WV range of PCE Instruments

Wind Direction sensor designed for di󰀨erent industries and sector

PCE-WV detects the vane position by using

magnetic sensors avoiding wear and tear. It

generates a 4-20mA analogue output or RS485

MODBUS signal, depending on version. The heated

version generates 4-20mA output and works from -20

ºC. When the temperature is higher than +6º C, the

heater switches itself o󰀨 automatically to reduce the

consumption.

High resistance to radio frequency interference

PCE-WV SERIES

APPLICATIONS

PCE-WV series has been designed to be used in industrial

applications. Connected to devices such as dataloggers, PLCs,

analogue signal displays (see our reference PCE-DPD-U), it

measures the wind direction and/or activates predened alarm

values.

Application examples:

Irrigation control system, automation in greenhouses, solar

trackers, ropeways at ski resorts, cranes, wind turbines,

weather stations etc. All those applications that contribute to a

greater control and greater security. Besides, PCE-WV AH has

been designed for those applications that involve working with

sub-zero temperatures.

DIMENSIONS

OPERATING

Survival speed: 200 km/h of wind speed

It gives a RS485 MODBUS signal or 4-20 mA analogue output

which depends on the wind speed. (see graphic)

The vane must be orientated north as shown in the orientation

section.

RS485 version gives the wind direction in degrees. It calculates

the average position in the last second. In static position it has

20 positions of 18º each one.

The heater works from -20ºC up to +6ºC. Above this

temperature, it switches itself o󰀨 automatically to reduce the

consumption.

The wind vane must be xed on a vertical position.

PCE-WV CABLE

To orientate the vane north, the vane edge must be orientated north as shown

in the picture.

Once the vane has been orientated north, the output signal will correspond to

the angles and directions in the table.

uncertain

NOTES:

• There is no version with both outputs (analogue

and RS485).

• The output of the 1s AVERAGE versions when

the vane is moving is a continuous analog output

as result of the average of the last second. When

the vane is static, the output has 20 positions of

18º each one.
