Level Transmitters Model LV 37

Description : 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. 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). Features : measuring ranges: 0 0.6, ..., 0 200 mH2o output signal: 4 20 mA, option with HART protocol; or 0.5 5 V amplified output signal combined error: 0.25%fso (standard), 0.5%fso compensated temperature ranges: 0 50 oC materials: 316L (pressure membrane); 316 (housing) construction: integrated construction, rigid and robust probe and cable protection: IP 68; housing environment protection: IP 65.
