LMK 351 Product Highlights
The LMK351 Level Transmitter is a versatile device designed to accurately measure liquid levels across various applications. With a nominal pressure range spanning from 0 to 40 mbar up to 0 to 20 bar, it can accommodate a wide range of pressure requirements. The transmitter offers two output signal options: a 2-wire configuration providing a 4-20 mA signal, and a 3-wire configuration offering a flexible output range of 0-20 mA or 0-10 V, with the ability to provide other output options upon request.
The LMK351 is equipped with a pressure port made of PVDF, making it suitable for measuring aggressive media, while an alternative version with a G 1 1/2″ pressure port is available for pasty and polluted media. Additionally, the transmitter offers optional versions, such as an IS-version Ex ia, which is intrinsically safe for gases and dust, and a diaphragm made of 99.9% AI2O3 (alumina). It can also be customised to meet specific customer requirements. The LMK351 Level Transmitter provides reliable and flexible level measurement solutions for a variety of challenging environments and applications.
Screw-in Level Transmitter Applications
The LMK 351 Level Transmitter is highly suitable for plant and machine engineering, where precise and reliable level measurement is essential for the safe and efficient operation of industrial processes. In these environments, the transmitter can be integrated into automated systems to monitor and control the levels of various liquids within tanks, reservoirs, or process vessels. Its robust construction and compatibility with a wide range of media make it ideal for use in demanding industrial settings, ensuring consistent performance even under challenging conditions.
In the field of environmental engineering (water-sewage-recycling), the LMK 351 plays a crucial role in monitoring water levels in treatment plants, sewage systems, and recycling facilities. Accurate level measurement is vital for managing water resources, preventing overflows, and ensuring compliance with environmental regulations. The transmitter’s ability to withstand aggressive and contaminated media makes it particularly well-suited for these applications, where reliability and durability are paramount.
The LMK 351 is also designed for use with fuel and oil, making it an excellent choice for applications in the energy sector, such as fuel storage tanks, oil reservoirs, and distribution systems. Its compatibility with hydrocarbons and resistance to corrosive substances ensure that it can provide accurate level readings in environments where safety and precision are critical. This helps operators maintain optimal inventory levels, prevent leaks, and ensure the safe handling of potentially hazardous materials.
Finally, the transmitter is adept at measuring levels in viscous and pasty media, which are commonly found in industries such as food processing, pharmaceuticals, and chemicals. The LMK 351’s flush-mounted diaphragm prevents clogging and allows for reliable measurement of thick, sticky, or particulate-laden substances. This capability is essential for maintaining process efficiency and product quality in applications where traditional level sensors might struggle or fail.
