Description
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.

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
