说明
The 800AS Series Pressure Transmitter is specially designed for mud, slurry, and mineral pulp applications where conventional pressure sensors are prone to blockage and leakage. It adopts a hard flat diaphragm structure combined with strain-gauge sensing technology, ensuring accurate pressure measurement while preventing clogging.
The transmitter uses premium silicon wafers and a precision signal processing circuit board for fast sampling speed and strong anti-interference performance. The stress-slot diaphragm design improves accuracy in low-range measurements. A high-strength glass cover protects the optional 4-digit LCD display, providing clear and stable readings even in harsh environments.
With a wide selectable pressure range and multiple output options, the 800AS transmitter delivers reliable performance for demanding industrial conditions.
