Surge Protector
Vaisala recommends using surge protectors when weather instruments
are installed in areas with an elevated risk of lightning strike, such as on
top of high buildings or masts, or in open areas.
Surge protectors are also recommended if your cable length exceeds
10 m or you have unshielded, open-wire lines.
Vaisala provides the following surge protectors:
-
Vaisala Surge Protector WSP150.
A compact transient overvoltage suppressor designed for outdoor
use. It can be used with all Vaisala wind and weather instruments.
Install WSP150 close to the protected instrument (maximum 3 m).
-
Vaisala Surge Protector WSP152.
Designed for use with Vaisala WXT transmitters and WMT
sensors. WSP152 protects the host PC against surges entering
through the USB port. Install WSP152 close to the PC, no further
than the USB cable can reach (1.4 m).
