Analog Sensors—100 Ω Platinum RTD
Description
100 ohm RTD sensors provide input for accurate loop
powered temperature sensing (detecting) via a
20 AWG twisted, shielded cable pair. The loop current
varies according to the temperature being measured.
Several models are available for specific mounting and
sensing applications.
