Fiber‐Optic Systems (fiber‐optic input/output models only)
Fiber optic input models accept optical signals from AW Gear Meters FOP‐20 or FOP‐30 fiber optic
transmitters using AW Gear Meters fiber optic cable. Fiber‐optic output models transmit a scaleable 0‐
100 Hz signal via fiber‐optic cable to the AW Gear Meters OPTV‐20 or OPTV‐CM fiber optic receiver.
