RT9420-0003-121-1120详细描述
t Industrial Grade – Up to 50 Turns
t 4...20 mA Output Signal
t Intrinsically Safe
Specification Summary:
The RT9420 provides rotational position feedback
via 4...20 mA current loop signal. This
device combines the superb linearity ａnd resolution
of a plastic-hybrid potentiometer ａnd the
durability of Celesco’s 4...20mA circuit to provide
an accurate ａnd reliable electrical signal.
Additionally the zero ａnd span settings
are adjustable through access holes in the
housing.
This innovative sensor from Celesco, designed
to meet NEMA-4 ａnd IP67 standards,
is available in full stroke ranges of 1/4 to 50
turns.
