The LMK307 submersible level sensor is designed for measuring the depth of leachate in holding tanks. This robust sensor features a 4-20mA output signal with ATEX IS certification, making it suitable for hazardous environments where flammable gases or vapors may be present. With a measurement range of 0 to 5 meters water gauge (mWG) and a 10-meter long PVC cable, it offers reliable and accurate level measurement in various leachate collection applications.
Leachate, a liquid generated from the decomposition of waste in landfills, typically contains a complex mixture of dissolved organic and inorganic substances. Monitoring the leachate level in holding tanks is crucial to prevent overfilling, ensure proper functioning of the leachate collection system, and comply with environmental regulations. The LMK307 is specifically designed to withstand the harsh conditions encountered in leachate applications. Its FKM seals provide excellent chemical resistance to the corrosive nature of leachate, ensuring long-term durability and performance.
The sensor’s 4-20mA output signal allows for easy integration with existing process control systems, enabling remote monitoring and automated control of pumps or alarms. The ATEX IS certification ensures safe operation in potentially explosive atmospheres, making it suitable for installation in hazardous areas commonly found in landfill sites. The 10-meter long PVC cable provides flexibility in installation, allowing the sensor to be positioned at the optimal depth within the holding tank.
The LMK307 is a reliable and cost-effective solution for leachate level measurement in holding tanks. Its robust construction, chemical resistance, and ATEX certification make it ideal for demanding applications in the waste management industry.
