The PT-301 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. Because its structure can withstand great destructive pressure, it is extremely safe and is the preferred ceramic pressure transmitter for use in demanding workplaces. It is widely used in automobiles, food, medicine, industrial automation, water pumps, petroleum, chemical industry, etc. Pneumatic equipment, hydraulic equipment, air conditioners, air compressors and other fields.
