OBAI-3051G2 Remote transmission flange liquid level transmitter
Product Related Description
Product Overview
OBAI-3051G2 remote flange level transmitter is a high-precision, high-stable, multi-parameter pressure/level measurement product that complies with the HART protocol. This transmitter is welded and installed with a capillary remote transmission flange on the differential pressure transmitter structure and filled with silicone oil to avoid direct contact between the medium and the differential pressure transmitter diaphragm. The diaphragm on the flange can be made of different materials according to the characteristics of the medium. It is suitable for liquid level measurement of high temperature, corrosion, suspension, viscous, easy to crystallize and other media.
Main Features
♦The central sensing unit of the single flange liquid level transmitter adopts the world's leading sensor technology
♦The sensor adopts digital compensation and non-linear correction, with an adjustable range ratio of up to 100:1
♦IP65 protection design, suitable for harsh environment sites such as outdoors and open air
♦Full film covering the sealing surface, suitable for liquid level measurement in high temperature, highly corrosive and other media
♦Digital circuit design, can be cleared on-site by pressing a button
♦EMC complies with GB/T18268.1-2008 standard
♦Comply with GB3836 standard requirements and obtain explosion-proof certificate
