LMK 306 17mm Submersible level transmitter for hydrostatic level measurement


The LMK 306 uses a ceramic pressure sensor of 15mm diameter to achieve the 17mm diameter body in 316Ti stainless steel.  Level ranges are from 6mWG up to 200mWG and cable options of PVC, PUR and FEP.  Standard output is 4 - 20mA / 2-wire and powered from 12 to 36V dc.

The LMK 306 has been designed specifically for liquid level measurement in small <1" diameter boreholes or survey tubes.  This small diameter liquid level transmitter is ideal for accurate measurement of level and uses a ceramic pressure sensor to measure the level hydrostatically when submersed in the liquid.  It has measurement ranges from 6mWG through to 200mWG which is calibrated to a 4-20mA 2-wire output.  As standard the product has lightning protection to protect against lightning when installed in rivers, reservoirs or boreholes.  There are also options for the cable sheath used such as PVC, PUR or FEP to enable full compatibility to the media being measured.
