Model LV36 Hydrostatic liquid level transducers and transmitters with flush diaphragm is designed for a wide variety of level measurement applications. This model pressure sensor and is protected by the stainless steel (SS) housing. Featuring the flush diaphragm makes the LV36 suitable to measure viscous media or media with small particles, so as to have diverse measurement applications.The standard reference pressure is gauge (or relative) pressure realized through a vent tube in the cable. The reference pressure can also be absolute pressure on request.The measuring range of LV36 transmitters spans from 0~1 to 0~200 meter water column (mH2O) withmeasuring accuracy of 0.5%fs (fs = full scale). The output signal of transmitters can be configured toeither current loop (4~20mA,standard), voltage output (0.5~4.5V, 1~5V), or digital output (I2C orSPI). The millivolt signal directly from the Wheatstone ridge circuit is also available on request(transducer version).
