The precision air pressure difference sensor controller is specially designed by our company for positive pressure air supply systems (front room stairwells A special product developed for pressure difference control in underground shelters, etc. This product uses high-precision and high-stable sensors imported from the United States and is equipped with a high-performance amplification circuit. Four-digit numbers display the measured pressure difference value and the set pressure difference value. The alarm indicator light display casing adopts The wall-mounted front end adopts a diameter compression ladder tube, which is easy to use and reliable to connect, ensuring that the product has good sealing and protection levels.
High-quality sensors, precise amplification circuits, strict production processes, and complete inspection and aging testing equipment ensure excellent product quality. This product is widely used in front room (common front room) pressure difference measurement and control systems, closed refuge floors, smoke-proof stairwell pressure difference measurement and control systems, indoor and outdoor pressure difference detection, filter clogging monitoring systems and other dry gas pressure difference measurement and control systems
Features
: Using the pressure differential core imported from the United States with high precision and good stability
: Four-digit display of the actual measured pressure difference value and set value
: With zero point and full-scale compensation and temperature compensation Advanced design
: Adopt high-precision and high-stability high-performance amplification circuit with good stability
: Power supply and signal output adopt bus system transmission
: The system adopts bus system to connect single machine and independent working mode. The failure of one device will not affect the normal operation of the other equipment
