Introduction MPM4780 Intelligent Transmitter is a highly integrated measurement product with high stability.It uses intelligent processing circuit, the most advanced design and manufacturer technology of piezoresistive pressure transmitter, and is available for pressure signal and temperature signal output that in accordance with standard MODBUS-RTU protocol. Featuring integrated design, standard digital output, great compatibility, small size, high accuracy, light weight and wide pressure range, it can be applied in many fields which involve high accuracy required measurement of fluids. It also can take replace of pressure and level transmitters in the form of MODBUS protocol output by providing pressure type and level type measurement for users. Features • RS485 communication interface, Standard MODBUS-RTU Protocol output; • Netting available; • Short protection and reverse polarity protection; • Full stainless steel construction, compact size, light weight • Good output consistency and replaceability. • Available for calibration and parameter change on site through matched soft of upper computer.

Assistant Software MPM4780 Transmitter Software RS232/485 Conversion module is used to communicate with RS485 interface transmitter, available for real time pressure/temperature display and calibration on site. Some parameters calibration was done before being transported at factory, so users do not have to modify them. When mistaken operations happen,users can push “Back to Factory Setting”to turn it to factory setting. Besides, the software keeps Data Record section, which allow users to set the record interval freely for recording and saving data, and the data can be saved in the forms of...
