^1When pipe temperature is 100°C212°For more, the display amplifier cannot be mounted on the pipe clamp unit. Install the amplifier so it is insulated from the heat from the pipe. ^2This is the guaranteed value from verification performed at KEYENCE inspection facilities. Measurement error may occur depending on the type and condition of the customer’s pipes and fluid, the ambient temperature and other factors. ^3This is the value for a constant 25°C77°Fenvironment, taking into account absolute error and repeatability. ^4During standalone use, 220 mA or less including load. ^5When connecting to a FD-H Series/FI-1000 model, please follow the specifications of the display unit. ^6中rts IO-Link specification v.1.1/COM2 (38.4 kbps).
