Easy Installation and Operation
The WILSEN.valve and WILSEN.node solutions can be conveniently configured for their intended purpose via downlink channel remote access or directly on site with a mobile device app (Android or iOS).
Highly-Customizable Sensor Solutions
A comprehensive range of connectable sensors and optional accessories from a single source ensures that your WILSEN.valve or WILSEN.node sensor solution is precisely tailored to your application requirements.

WILSEN.valveSmart Valve Position Feedback
In many process plants manual valves are used that are only operated occasionally or in emergencies and are not connected to the control room. The WILSEN.valve sensor solution monitors the position of such valves and reports the status to the responsible authority via LoRaWAN over a distance of several kilometers. This additional information turns the WILSEN.valve into an effective M+O (Monitoring and Optimization) sensor solution that minimizes the risk of costly and time-consuming malfunctions caused by unintentionally opened or closed valves. For this purpose, robust inductive and energy-optimized single or dual sensors from the broad Pepperl+Fuchs portfolio are quickly and easily connected to the WILSEN.valve central unit via standardized M12 connections.

Wireless Valve Position Feedback
The WILSEN.valve solution is optimized for wireless monitoring of up to two valves.
Inductive Sensor Technology
The WILSEN.valve solution utilizes robust, wear-free inductive sensor technology.Easy Application Integration
Due to a variety of mounting aids, integrating the WILSEN.valve is quick and easy.Four Versions Available
The WILSEN.valve central unit is available in four different versions to optimally meet every application profile.
The Components

The central unit supplies the sensors with power via a high-performance battery and reports the valve status detected by them to the target system. As the valve status is sent directly and already processed, there is no need for users to carry out a complex evaluation of individual sensor statuses and assignment to the respective valve status. The integrated GPS functionality of the central unit also makes it easy to localize the valves, even in widely branched process plants. Furthermore, the central unit also transmits additional diagnostic data and reports error states such as line breakage or short circuits to the higher-level system.

Depending on the application or valve type, the Pepperl+Fuchs portfolio includes different types of inductive NAMUR or 2-wire low-power DC single and dual sensors. The sensors are connected to the WILSEN.valve central unit via standardized M12 connections, whereby cable lengths of up to 10 m can be selected. For easy installation on standard valves and fittings, an EN ISO 5211-compliant mounting solution is available, which includes mounting brackets and plates as well as complete mounting sets.

WILSEN.nodeSmart Object Presence Detection
The WILSEN.node is the universal object presence detection solution among M+O wireless sensors. The central unit is ready for connection of up to two suitable sensors from the broad Pepperl+Fuchs portfolio. Both channels of the central unit work independently of each other so that sensor types can also be combined with each other. Due to the extensive range of functions, a wide variety of applications can be implemented cost-effectively. Especially in retrofit scenarios or in applications that have to be implemented in remote, hard-to-reach locations without a conventional power supply, the WILSEN.node proves to be an ingenious yet easy-to-implement solution.

The WILSEN.node central unit is available in two different versions to optimally meet every application profile.
The Components

The central unit supplies the sensors with power via a high-performance battery and transmits information via LoRaWAN over a distance of several kilometers. In addition to the actual sensor measurement data, additional diagnostic data and error states, such as line breakage or short circuits, are also sent to the higher-level system. Integrated GPS functionality also enables the precise localization of central units in remote locations.

The central unit of the WILSEN.node allows the connection of up to two suitable sensors from the broad portfolio of industrial sensors from Pepperl+Fuchs. These can be inductive or capacitive NAMUR or 2-wire low-power DC proximity sensors. It is also possible to operate float switches or vibration limit switches on a central unit, so that liquid media and bulk solids can also be detected wirelessly with the WILSE.node solution. The sensors are easily connected via standardized M12 connectors.

KnowledgeHow Does it Work?
A so-called LoRaWAN (Long Range Wide Area Network) is required to transfer measured values from the WILSEN IoT sensors to a cloud-based IoT platform and evaluate them there. These easily scalable networks, which are fully geared towards the requirements of the IoT, are characterized by their combination of low energy consumption, long range and secure communication.
In addition to the IoT sensors or other end devices, such a LoRaWAN architecture usually consists of long-range gateways arranged in a star topology. These gateways translate the data from the WILSEN sensors into an Ethernet-capable protocol and transmit the converted information to a LoRa network server. The network server decodes the sensor data and forwards it to an application server for initial processing before the data can finally be evaluated in an IoT platform.
At the same time, communication in the opposite direction is also possible via the LoRa network server and the gateways: not only can sensor data be received, but parameter settings in the WILSEN sensors can also be conveniently made remotely via the so-called "downlink channel". Pepperl+Fuchs provides a free web service specifically for this purpose.
Alternatively, the sensors can be parameterized directly on site using a mobile device app.
