Monitor hot, aggressive leachate in landfill wells with the LMK 809 submersible level transmitter. Features PP-HT housing and ceramic diaphragm for superior corrosion resistance.
The LMK 809 submersible level transmitter is ideally suited for monitoring hot leachate levels in landfill wells up to 20 meters deep. Landfill leachate can reach temperatures exceeding 60°C, and its complex composition often includes corrosive substances that can damage typical level sensors. The LMK 809 is specifically designed to withstand these harsh conditions. Its PP-HT (high-temperature polypropylene) housing offers excellent chemical resistance to aggressive leachate, providing a more durable alternative to stainless steel in this application.
A key feature of the LMK 809 is its ceramic Al2O3 99.9% diaphragm. This highly inert material provides superior protection against the corrosive nature of leachate, ensuring long-term accuracy and reliability in level measurement. The use of FFKM (perfluoroelastomer) seals further enhances the sensor’s resistance to aggressive media, preventing leaks and maintaining measurement integrity.
With a 40-meter TPE cable rated for temperatures up to 100°C, the LMK 809 allows for safe and reliable signal transmission from the sensor to the junction box, even in high-temperature environments. The detachable nose cone on the submersible probe facilitates easy cleaning and maintenance, a crucial aspect in landfill applications where debris and sediment can accumulate. This design ensures the long-term performance and accuracy of the level measurements. The LMK 809‘s flush diaphragm design minimizes potential clogging issues, making it suitable for use in leachate, which often contains suspended solids. This feature is crucial for maintaining the accuracy and reliability of the level measurements over time.
For applications requiring remote monitoring or data logging, the LMK 809‘s 4-20mA output signal can be easily integrated with various control systems and data acquisition devices. This enables continuous monitoring of leachate levels, facilitating efficient landfill management and environmental protection.
