^1 When pipe temperature is 100°C 212°F or 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. ^2 This 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. ^3 This is the value for a constant 25°C 77°F environment, taking into account absolute error and repeatability. ^4 During standalone use, 220 mA or less including load. ^5 When connecting to a FD-H Series/FI-1000 model, please follow the specifications of the display unit. ^6 Supports IO-Link specification v.1.1/COM2 (38.4 kbps).
