Honeywell STD974 Differential Pressure Transmitter / đo áp suất

Differential Pressure Transmitter

Differential Pressure Transmitter Honeywell STD974 series of intelligent differential pressure transmitter is based on the microprocessor-based intelligent transmitter. The latest R300 version, to enhance the accuracy of the transmitter, reliability and long-term stability indicators. It can measure a variety of liquid and gas differential pressure, pressure or level, and output the corresponding 4 ~ 20mA analog and digital signals. Its unique temperature and static pressure error automatic correction function to make it meet the harsh environment. It has DE communication protocol, with Honeywell’s ExperionPKS distributed control system and intelligent field communicator (SFC) to achieve two-way digital communication, eliminating the analog signal transmission error, to facilitate the transmitter debugging, verification and fault diagnosis The
