Description:
The LV37 liquid level transmitters provide amplified output signals such as 0~5 V or 4~20 mA, with an option of HART for current output. These transmitters can also be quipped with a 4½ digits LCD field display. The measuring accuracy of model LV37 is up to 0.25%fso (fso = full scale output).
ordering code example: LV37 - 0/20 mH2O - 4/20 mA with HART - 0.25%fso - 5 m - 4 ½ digits LCD display
Based on BCM piezeresistive technology, model LV37 submersible liquid level transmitters are designed for gauge (relative) pressure application in liquid level measurement. These level transmitters are made from 316L stainless steel with rigid and robust construction, cable with vent hose for submersible applications.
