The PT-509 pressure transmitter uses a 96% alumina sensor core. Through a highly reliable amplification circuit and precise digital temperature compensation and non-linear correction technology, it converts the pressure of the measured medium into a 4~20mA, 0~5VDC analog Signal. Professional waterproof hammer design, its structure can withstand great damage pressure, so its safety is extremely high. It is the first choice ceramic pressure transmitter for use in high-demand workplaces. It is widely used in automobiles, food, medicine, industrial automation, water pumps, etc. Petroleum, chemical industry, pneumatic equipment, hydraulic equipment, air conditioning, air compressor and other fields.
