The LV3000/LV4000 level sensors for continuous level measurement are flexible, cost-effective solution for applications involving liquids, pastes, and solids. The built-in (one-piece) electronic module provides a 4 to 20 mA output (2-wire) signal that is proportional to the process level. Zero and span adjustment helps account for various media, tank dimensions, rod lengths, and positions of installation.
OMEGA™ offers these probes in several different models. The user must choose the probe that suits his or her application and install it in the proper location. When submerged, the probe must be able to produce enough capacitance variance. The probe’s success depends on these important factors:
OMEGA™ offers these probes in several different models. The user must choose the probe that suits his or her application and install it in the proper location. When submerged, the probe must be able to produce enough capacitance variance. The probe’s success depends on these important factors:
A) Conductive materials can cause a short circuit between a bare stainless steel probe and the tank wall. For this situation, we recommend using PTFE sleeving on the rod surface.
B) Material buildup affects the accuracy of RF capacitive measurements. Additional adjustment to the probe’s sensitivity is therefore recommended.
Housings must be compatible with the requirements for hazardous, washdown, wet, or dusty environments. For explosion-proof environments, the housing may need to be certified. In addition, the active probe might need to be intrinsically safe or have an intrinsic safety barrier.
The electronic circuitry of the probe performs several functions, such as rectifying and filtering the incoming power, generating the radio frequency signal, and measuring the changes in current flow.
