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.

Assistant Software

a) Transmitter Software (RS485 Interface type) MS Setonline Software

Through RS232/485 conversation module, the user could read inner basic information for RS485 interface transmitter (including level range,compensated temp.range, version code, etc.) and display actual level, set new zero, analog output and deivce

Note: Software “MS Setonline” could be downloaded from our website



b)Transmitter Software (HARTâprotocol)

HART-CONFIG Tool SoftwareThrough MS-HARTâ357 conversion module, the user could calibrate and adjust HARTâ transmitter.
