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.
