Product Description 

The LMK351 high abrasion resistant level sensor incorporates ceramic capacitance diaphragm technology which exhibits high accuracy and over-pressure at low liquid levels.

The capacitive aluminium oxide (Al2O3) ceramic sensing diaphragm of the LMK351 chemical level sensor is highly resistant to abrasive materials and corrosive chemicals such as acids and alkalines. For chemicals that are not compatible with stainless steel 316Ti there is the option for PVDF screw-in fittings.

For installations where frequent external washdown of storage tanks and equipment is required an IP68 cable gland can be selected for the LMK351 aggressive media level transmitter to make it waterproof.

A liquid level range from 1.3 up to 656 feet of water column can be specified for the LMK351 low range chemical level sensor with measurement accuracy of ±0.35 or 0.25% full scale.

For hazardous areas with volatile gases or dust present the LMK351 chemical level sensor has optional ATEX approved intrinsically safe electronics for use with IS barriers.
