CHR3500 Series RS485 Intelligent Pressure Transmitter

La description

Introduction CHR***0 is a kind of highly accurate and stable intelligent pressure transmitter. It uses the most advanced digital technique, temperature compensation, linearity correction and reliable ex-proof construction for production. The product has compact size, standard 4～*0mADC and RS**5 signal output to measure flow pressure precisely. CHR***0 uses *-wire output with zero automatic adjustment and temperature automatic compensation function, and good antijamming capability. The users could manage, adjust or monitor the process variables by HART® communicator, and it could also be configurated by key-press at local working place.
