Digital RS485 HART Pressure Transmitter

The MPM4730 digital RS485 HART pressure transmitter utilizes piezoresistive technology and specially designed electronics to provide high accuracy of 0.15%FS in a temperature range of -20~80℃. It offers both analog and digital signal outputs, including 4~20mA, RS485-Modbus, and HART protocol. By incorporating digital temperature compensation, non-linearity correction techniques, and advanced production methods, the MPM4730 pressure sensor ensures stability, accuracy, and a wider pressure range. This compact, lightweight, intelligent pressure transmitter is ideal for precise measurement of flow pressure.
The MPM4730 pressure measurement instrument is suitable for process control, water treatment, chemical and mechanical equipment, offering versatile solutions for pressure monitoring needs.
