Air conditioning refrigeration pressure sensor
The PT-401L pressure transmitter adopts a 96% alumina flat film sensor core, which converts the pressure of the measured medium into a 4-20mA, 0-5VDC analog signal through a highly reliable amplification circuit, precision digital temperature compensation, and nonlinear correction technology. Due to its structure that can withstand extremely high destructive pressure, it has extremely high safety. Even if the pressure sensing membrane breaks, the measured medium is not easily leaked out of the sealed body, which will not cause pipeline pressure loss. It is the preferred ceramic pressure transmitter for use in some workplaces with high safety requirements. It is mainly used in water-cooled screw units, ground source heat pumps, freezers, chillers, ice makers, air conditioning systems, etc. Its unique anti condensation water design plays a pressure protection role for the safe and efficient operation of equipment
