MPM4700 Intelligent Level Features • 4mA~20mA DC 2-wire current output; • Digital temperature compensation and linearity correction; • RS485 communication interface(Custom protocol) or HART®communication protocol(optional); • Netting application; • Full stainless steel construction, compact size, lightweight; • Special requirement available; • RoHS Certificate; • Intrinsic safe ex-proof version conforming to GB3836.4 Exia II BT6 Ga Regulation; Ex-proof Certificate is issued; • Marine type products accord with CCS classification of sea-going steel ships of the rules "(2006) the requirements, has obtained the type approval. Introduction MPM4700 level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction technics for production. The water-proof cable connects with housing sealed, with vented tube putting in, the transmitter could be used in the water or liquid in a long time. Integrated construction and standard output signal could provide easy operation and good automatic control. With 2-wire working, compact size, light weight and easy installation and operation, it is widely used for industry field instead of normal 2-wire 4~20mADC analog output transmitter. Specifications Basic range (mhhO) 3.5 7 10 20 35 70 100 200 Note: The min.shrinked available range is 1/5 of basic range; For the other pressure range between min.range and max.range, but not indicated on the above table, we enlarge the above basic pressure range to produce (overpressure unavailable); MICRO SENSOR CO.,LTD
