Level sensor for every level measurement

Details: Released: 25.07.2023; Last updated: 26.06.2024; Hits: 9222

level sensors, also known as level gauges or level sensors, are devices that are used to measure the level or quantity of a medium within a container or tank or are used for limit level detection. They are required in many applications for continuous level measurement, such as in the process industry, Food industry, chemical industry, water and waste water treatment and many more. Pepperl + Fuchs has a solution for every application.

Autonomous IoT wireless sensor nodes for seamless network connectivity

Pepperl Wilson Level 26.06.2024 | Pepperl+Fuchs improves the IoT landscape with autonomous radio nodes Wilsen.valve and Wilsen.node, These car's battery performanceoperated devices eliminate the cablingThey reduce maintenance effort in large-scale systems and enable the reliable connection of assets. They deliver precise measurement and position data and simultaneously monitor the status of the connected sensors.

Every Wilsen device is equipped with lorawantechnology for radio connection and an integrated GPS receiver. Wilsen.valve is specially designed for valve position feedback and can process data from up to two inductive double sensors. This allows the position of up to two 90° manual valves to be monitored without having to lay cables.

Wilsen.node is particularly suitable for connecting Two-wire sensors in level measurement technology. It is used to monitor manhole covers, gates or gates. In addition, float switches and vibration limit switches can be connected to monitor level limits and other parameters.

The Wilsen devices work completely autonomously and, depending on the query frequency and sensor type, achieve a battery life of up to 10 years. Parameterization can be carried out on site using an app and Bluetooth or location-independently using a Lorawan downlink channel. Both versions are compatible with two-wire low-power DC sensors and Namur sensors using different technologies. Pepperl+Fuchs offers numerous energy-optimized sensor types for this purpose.

All-rounder for level measurement

With the level switch Vibracon LVL-M3 and -M4, Pepperl+Fuchs offers two new series of vibrating level switches. With their Atex and IECEx approvals, they are suitable for use in potentially explosive areas worldwide.

The level meter LVL-M3 is suitable for universal use in all pumpable liquids. The vibrating level switch withstands process temperatures from -40° to +150 °C and process pressures of up to 40 bar.

The LVL-M4 variant is ideal for security applications up to SIL 3The sensor can withstand process temperatures from -50° to +150 °C and process pressures of up to 100 bar. As a special highlight, the LVL-M4 variant has a Bluetooth interface for the level sensor, which can be used to connect the level limit switch to the Level App from Pepperl+Fuchs. This mobile application offers a wide range of options - from status and error display to carrying out repeat tests.

The vibrating level switches of the Vibracon series do not have any mechanically moving parts and therefore offer a special long service life. Thanks to the plug-and-play principle, there is no need to calibrate to different media. A large selection of process connections and electronic inserts allows flexible adaptation to different environments.

IoT level sensors monitor level and position

Pepperl+Fuchs presents new sensor concept Wilsen.sonic.level. 16.01.2020/XNUMX/XNUMX | With the Level sensor concept "Wilsen.sonic.level" from Pepperl + Fuchs The fill levels of liquids and bulk materials in containers, tanks or silos can be monitored remotely using the Internet. The IoT sensor has an integrated ultrasonic fill level measurement for measuring fill heights, fill levels and water levels. These measured values are recorded at regular intervals and transmitted to the Internet together with the current geoposition. The autonomous radio sensor is battery-operated and thus enables the fill level in mobile containers to be measured.

The Wilsen.sonic.level is suitable for level applications in different radio networks. One version is with GSM (2G) interface for public cellular networks fitted. Another has a Lora WAN interface for the use of privately operated low power radio networks. The respective radio interface is used to transmit the sensor data to the Internet.

Depending on the radio standard selected, a corresponding counterpart waits on the Internet for the incoming sensor data from the level measurement. Lorawan devices their telemetry data to the network and application server of any Lora network operator. For applications with the public mobile radio standard GSM, the Wilsen.service middleware is available as a secure counterpart for the telemetry data results from the sensor.

System concept of the Wilsen.service

The system concept of Wilsen.service ensures the decryption and targeted forwarding of the sensor data. It also offers convenient and secure device management. These measuring principles are particularly advantageous when many IoT sensors are used. They are to be registered in the wireless network as automatically as possible and assigned to their legitimate users.

In addition, Wilsen.service device management allows the user to automate Application parameterization the IoT Sensors and a structured roll-out for software updates. In this way, a large number of IoT sensors can be kept up to date in the field for level measurement.

The Wilsen measurement method provides for a modular IoT system in which the individual components such as radio nodes, sensor modules, data processing and middleware can be supplemented additively.
