Introduction

MPM4780/4780w Intelligent Pressure/Level 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, MPM4780 pressure transmitter and MPM4780W level transmitter 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-RTU protocol output by providing pressure type and level type measurement for users.
