PT-511 pressure transmitter adopts a 96% alumina ceramic sensor core. Through a highly reliable amplification circuit combined with precise digital temperature compensation and nonlinear correction technology, it converts the measured medium pressure into 4–20 mA or 0–5 VDC analog signals, with direct digital display via a digital tube. Its structure can withstand extremely high burst pressures, ensuring exceptional safety. As a result, it is the ideal choice for demanding applications and is widely used in automotive, food, pharmaceutical, industrial automation, water pumps, petroleum, chemical, pneumatic equipment, hydraulic systems, air conditioning, and air compressors.
