CYG1808 high-precision digital pressure sensor adopts low-power, wide voltage digital circuit. The power consumption is not greater than 4mA without data communication, and its operating voltage range is wide up to 7-24 VDC. It can be powered by solar energy or batteries, or by 24VDC power supply from industrial sites.
CYG1808 high-precision digital pressure sensor adopts RS485 communication interface, half duplex working mode, maximum communication rate of 38400BPS, and maximum sampling rate of 25 times/second. Use simple ASCII command format for operation. The internal design of this sensor integrates secondary lightning protection function to provide higher security for RS485 long-distance communication. It forms a twisted pair network through the RS485 bus and is suitable for computer measurement and control systems.
