Digital RS485 HART Pressure Transmitter

The MPM4730 digital RS485 HART pressure transmitter utilizes piezoresistive technology and specially designed electronics to provide high accuracy of 0.1%FS in a temperature range of -30~80℃. 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 digital 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 pressure instrument is suitable for process control, water & waste treatment, chemical and mechanical equipment, offering versatile solutions for pressure monitoring needs.
