WIAG-PT/DPT intelligent differential pressure/pressure transmitter

The WIAG-PT/DPT series transmitters adopt a modular design with a microprocessor as the core and advanced digital isolation technology in circuit design, which gives the instruments extremely high anti-interference performance and stability. Meanwhile, digital compensation technology is used to compensate for temperature and static pressure, improving measurement accuracy and reducing temperature drift. The transmitters feature excellent long-term stability, high reliability and strong self-diagnostic capability. In terms of structure, users can easily configure, set up and calibrate the transmitters via HART communication handheld terminal, external knobs and buttons on the display.
