DESCRIPTION
The RTD50CS is a 50-foot three-wire platinum RTD (resistance
temperature detector) used with monitoring and control systems,
such as our DigiTrace C910 or ACCS-30 controllers.
The RTD50CS can be installed directly to the controller using the
supplied 1/2-inch conduit fitting or to an RTD junction box where
RTD extension wire is used.
