  • 產品介紹
    A strain gauge input module uses a microprocessor-controlled integrating A/D converter to convert sensor voltage or current signals into digital data for load cell and stress measurement. The digital data is then translated into either engineering units, twos complement hexadecimal format or percent-age of full-scale range (FSR)according to the module ’s configuration. When prompted by the host computer, the data is sent through a standard RS-485 interface. The strain gauge input module offers signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from ground loops and power surges by providing opto-isolation of the A/D input and transformer based isolation up to 3000 VDC .
