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.

The Components

WILSEN.valve central unit without connected sensors

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.

Accessories for WILSEN.node sensor solution

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.

Application Examples WILSEN.valve

Valve Position Always in View

WILSEN.valve in process plant

Monitoring the end position and feedback of the valve position of drain and distribution valves provides important information for optimizing production processes. In addition, costly waste of process heat or products can be avoided by quickly identifying accidentally opened valves. The WILSEN.valve solution detects the valve position via an inductive dual sensor with two inductive sensor elements. These each monitor one of the two end positions (open/closed) of the actuator, completely wear-free and with low interference. The central unit, together with the sensor and actuator, can be quickly and easily installed directly on the valve and then transmits the valve positions to a target system over a distance of several kilometers via LoraWAN. In defined cases, an alarm or a follow-up action is triggered.

Data Basis for Reliable Water Distribution

WILSEN.valve monitoring several manually operated valves

Whether in a municipal supply operation, an apartment building or in an industrial process—manually operated valves must be in the correct position for the continuous supply of hot water or heating. The WILSEN.valve solution detects the position of valves and ball valves in water distribution systems, including in remote locations. Up to two inductive dual sensors can be connected to a central unit, allowing the IoT sensor solution to monitor up to two valves simultaneously. For particularly quick and easy installation, the dual sensor is attached to a mounting plate and the actuator is connected to the axis of the hand lever. The central unit can be placed on a wall or a strut near the valve, for example. The device transmits the position of the connected valves in the water distribution system to the target system via LoRaWAN with a high degree of reliability. On site, the valve position can also be identified on the actuator by means of a clearly visible marking.

WILSEN.node

Ensuring a Safe Manhole Cover

WILSEN.node monitoring a manhole cover

Wells, sewer access points and other manhole openings in the ground require a secure cover. A correctly fitted manhole cover prevents accidents and protects people and materials. With the WILSEN.node, the position of the cover can be continuously checked. The central unit is installed outside the manhole and connected to a suitable sensor on the inside, which detects the position of the manhole cover. The position of the manhole cover (open/closed) is transmitted directly to the desired target system via LoRaWAN. In addition, a float switch can be connected to the second input of the WILSEN.node central unit, which detects possible flooding of shafts, for example in the event of heavy rainfall. This creates a comprehensive sensor solution for manhole monitoring with just one WILSEN central unit.

Door Control in Transformer Station

WILSEN.node securing the door of a transformer station

Due to the high voltage of the incoming lines, there is a danger to life and the doors of transformer houses must be closed at all times. They may only be opened for maintenance work—after appropriate safety measures have been taken. The WILSEN.node solution can be used to ensure that the door of a transformer house is always properly closed when no maintenance work is being carried out. For this purpose, an inductive sensor is connected to the WILSEN.node central unit, which detects the closing status of the door and reports any change. If the door is opened outside of scheduled maintenance work, the sensor signal can trigger a defined alarm. The protection of residents and passers-by is ensured.

Remote Monitoring of Pasture Gate

WILSEN.node monitoring pasture gate

Grazing animals should remain on the allocated pasture for a fixed period of time. This is not only important for pasture management, but also a question of safety and liability. Consequently, the pasture gate must be reliably closed during this time. The risk of unintentionally open gates can be minimized with little effort using the WILSEN.node solution. Equipped with a suitable sensor for object presence detection, the device monitors the position of the gate. If it remains open unplanned, a signal is sent via the central unit to the relevant IoT platform, from which the farmer immediately receives the corresponding message. The WILSEN.node central unit has an extremely robust design, IP66/67 degree of protection and a wide temperature range of -25 to +70 °C. This makes it particularly suitable for outdoor use in the harsh conditions of an animal pasture.

Securing Barn Doors

WILSEN.node mounted on barn for door protection

Agricultural barns are used to store harvested crops, fodder and straw as well as agricultural machinery and equipment. These are often very valuable items. In order to protect them from the weather, damage and theft, the doors should be closed as long as no work is being carried out there or there are no operationally necessary entries and exits. Damage and loss can be prevented by using the WILSEN.node solution without the need for extensive wiring or complex installation. The WILSEN.node central unit is mounted on the inside of the door. Supplemented by the appropriate sensor for object presence detection, the WILSEN.node solution now records the position of the barn door (open/closed) and transmits this to an IoT platform, which informs the farmer via a push notification in the event of unintentional opening.

Topologie de LoRaWAN avec détecteurs WILSEN

ConnaissancesComment cela fonctionne-t-il ?

Un réseau étendu à longue portée (LoRaWAN, Long Range Wide Area Network) est requis pour transférer les valeurs mesurées par les détecteurs IoT WILSEN vers une plate-forme IoT basée sur le cloud et les évaluer au même endroit. Ces réseaux facilement évolutifs, entièrement adaptés aux exigences de l'Internet des objets, se caractérisent par leur faible consommation d'énergie, leur longue portée et leur communication sécurisée.

En plus des détecteurs IoT et autres appareils finaux, une telle architecture LoRaWAN est généralement constituée de passerelles longue portée disposées en étoile. Ces passerelles convertissent les données des détecteurs WILSEN en protocole Ethernet et transmettent les informations converties à un serveur réseau LoRa. Le serveur réseau décode les données des détecteurs et les transfère à un serveur d'applications où elles subissent un traitement initial avant leur évaluation finale sur une plate-forme IoT.

Dans le même temps, la communication en sens inverse est également possible via le serveur réseau LoRa et les passerelles : il est non seulement possible de recevoir les données des détecteurs, mais également de modifier les réglages des détecteurs WILSEN à distance via ce que l'on appelle le « canal de liaison descendante ». Pepperl+Fuchs propose un service Web gratuit dédié.

Les détecteurs peuvent également être paramétrés directement sur site via une application pour appareil mobile.
