Specialists in Level Detection and Distance\/Level Measurement<\/h3>\n\n\n\n
As part of the new generation’s introduction, the portfolio of WILSEN devices is being restructured. While devices for common level measurements continue to be marketed under the name “WILSEN.sonic.level,” dedicated\u00a0specialist devices\u00a0for distance and level measurements are now joining the\u00a0“WILSEN.sonic.distance”\u00a0type. Instead of a percentage fill level, these ultrasonic sensors transmit the\u00a0amplitude value\u00a0corresponding to the received echo. This provides information on how well the sensor is oriented to the object being detected, for example, and can also serve as an indicator for reliable detection of the object under current ambient conditions.<\/p>\n\n\n\n

In addition to the 2.5 and 4 meter versions, versions with a\u00a0detection range\u00a0of up to\u00a07 meters\u00a0are now available to users. This increased detection range broadens the range of applications for the LoRa wireless ultrasonic sensors and allows the detection of fill levels in\u00a0larger silos and tanks\u00a0or the level measuremen<\/a>t from\u00a0higher bridges, for example.<\/p>\n\n\n\n![\"\"](\"https:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/hmi5.jpg\")

With this new generation, LoRa communication via a\u00a0<\/strong>downlink channel\u00a0is also gaining traction with the WILSEN sensors: Once the devices are integrated into a LoRaWAN network,\u00a0parameter settings\u00a0in the sensor can be accessed remotely and easily queried or changed. Pepperl+Fuchs also provides a specially programmed\u00a0web service\u00a0for this purpose. With just a few clicks, downlink payloads can be created as HEX codes and transferred directly via the Network API Key to message queues in the\u00a0TTN (The Things Network) and ChirpStack (v3 and v4)\u00a0IoT platforms.<\/p>\n\n\n\nIf an IoT platform other than TTN or ChirpStack is used or no Network API Key is available, the HEX code can also be easily copied and pasted into comparable applications and sent there via downlink. A\u00a0downlink reply decoder, which is also integrated into the Pepperl+Fuchs<\/a> web service, allows confirmation messages from the WILSEN sensors to be decrypted into human-readable plain text.<\/p>\n\n\n\n![\"\"](\"https:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/hmi6.jpg\")

Furthermore, the downlink channel now allows the\u00a0measurement and transmission interval\u00a0of the WILSEN sensors to be adjusted to\u00a0ten minutes\u00a0without violating the\u00a0LoRaWAN air-time restrictions. This has advantages, especially in level measurement applications: In the event of predicted rainfall, the WILSEN is switched to the ten-minute measurement interval via downlink beforehand so that rapid level changes and possible flooding risks can be viewed immediately in the measurement data. After the rainfall, the sensor returns to its initial output status\u2014again via a downlink command\u2014to\u00a0preserve battery life\u00a0while performing its task.<\/p>\n\n\n\n
Calculating Battery Runtimes of LoRaWAN Sensors<\/h3>\n\n\n\n
To help optimize battery performance even further, Pepperl+Fuchs also offers a\u00a0free, web-based battery runtime calculator\u00a0with the new WILSEN generation. This tool allows users to calculate the expected battery life of their WILSEN sensors based on a number of parameters. These include the location (indoor or outdoor areas), measurement and transmission frequencies, and the quality of the LoRaWAN network at the operating location. The results of the calculation help to set meaningful and appropriate sensor parameters for the application and to achieve the\u00a0longest possible battery runtime. In addition, the tool can be used to\u00a0estimate battery replacement intervals\u00a0to avoid equipment failures and costly service work.<\/p>\n\n\n\n
