RTD TRANSMITTER Series W2RS

RTD TRANSMITTER

Model: W2RS

RTD TRANSMITTER

Model: W2RS - 1AA - M2

Functions & Features
• Accepts direct input from an RTD
• Linearization
• Burnout
• “Active bridge” circuit containing two constant current
sources allows large leadwire resistances up to 200 Ω
• Fast response type available
Typical Applications
• Long distance transmission between the RTD and the
transmitter
• Combination with intrinsic safety barriers
