PCE-WS P PULSES OU

PCE-WS P range of PCE Instruments

Wind Speed sensor designed for di󰀨erent industries and sector

PCE-WS P PULSES OUTPUT has a pulses
output proportional to the wind speed given by
a reed switch. In this way, the power supply
just needs to be enough to detect the contact
closing and opening, reducing the power
consumption.

APPLICATIONS

PCE-WS P have been designed to be used in industrial
applications: cranes, solar panels, buildings, wind turbines,
weather stations…
It is usually connected to tachometer displays ( see references
PCE-DPD-Px series), PLCs or data loggers to display the

wind speed and/or set alarms to predened values or to obtain
records during predened periods of time.

OPERATION

Outputs/Inputs

Up to 180 km/h of wind speed

Output: Dry reed contact, with a series resistance which

switches with a frequency proportional to the wind speed (see
graphic). It includes an internal capacitor that can be used as a

signal lter.
The wind sensor must be xed on a vertical position.

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants,
batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU devices must be properly disposed of in accordance with this regulation, we give
them to a recycling company which disposes of the devices in line with law. For countries outside the EU, batteries and devices should
be disposed of in accordance with your local waste regulations. If you have any questions, please contact PCE Instruments.

Contact information for each country and user manuals in various
languages can be found on our website: www.pce-instruments.com
