Monitor wastewater levels with this robust IP68 submersible sensor featuring a flush ceramic diaphragm and FEP cable. ATEX approved for hazardous areas.
The LMK307 IP68 sewage level transmitter is a submersible sensor designed for monitoring wastewater levels in challenging environments. This robust device is particularly well-suited for applications in sewage treatment plants, lift stations, and other wastewater management facilities where accurate and reliable level measurement is critical.
One of the key features of the LMK307 is its flush ceramic diaphragm. This design element not only provides a high level of corrosion resistance against the harsh chemicals and debris found in sewage but also allows for easy access to the sensor for cleaning and maintenance. This is crucial in preventing the buildup of waste materials that can affect the accuracy of the sensor readings.
The transmitter is equipped with a 10-meter long FEP-coated cable, offering excellent chemical resistance and ensuring longevity even when submerged in aggressive fluids. FEP (fluorinated ethylene propylene) is a fluoropolymer known for its high resistance to chemicals, solvents, and oils, making it an ideal choice for wastewater applications.
The LMK307 is designed with user convenience in mind. Its compact size and submersible design allow for easy installation in various locations, including tanks, sumps, and pipelines. The 4-20mA output signal is a standard in industrial instrumentation, ensuring compatibility with a wide range of monitoring and control systems. Additionally, the sensor’s ATEX approval makes it suitable for use in potentially explosive atmospheres, further expanding its application possibilities.
This sewage level transmitter is essential for maintaining optimal operational efficiency and preventing costly issues like overflows or pump damage in wastewater management systems. Its robust construction, coupled with the corrosion-resistant ceramic diaphragm and chemically resistant FEP cable, ensures long-term reliability and minimal maintenance requirements.
