nvent Raychem RTD3CS User manual

DESCRIPTION
The nVent RAYCHEM RTD3CS and RTD10CS are three-wire
platinum RTD (resistance temperature detectors) typically used
with monitoring and control systems, such as our
nVent RAYCHEM 910 controller, when accurate temperature
control is required.
The RTD3CS and RTD10CS can be installed directly to the
