LMP 305 19mm Submersible level transmitter for borehole and slimline level measurement


The LMP 305 is 19mm in diameter owing to the 17mm diameter silicon based isolated diaphragm pressure sensor installed internally.  This enables pressure ranges from as low as 1mWG up to 250mWG.  They have a calibrated 4-20mA output and run from a 12 to 36V dc supply.

The LMP 305 is a silicon based slimline submersible level transmitter with diameter in mind!  The pressure sensor element is 17mm in diameter enabling a body diameter of 19mm which is ideal for fitting into slim borehole pipes or installations where lots of instrumentation is installed.  The level range is from 1mWG through to 250mWG and has 4-20mA output as standard.
