RTD TRANSMITTER

(isolated)

Functions & Features

• Accepting direct input from an RTD and providing a

standard process signal

• Linearization

• Burnout protection

• "Active bridge" circuit containing two constant current

sources allows large leadwire resistances up to 200 Ω

• Fast response type available

• High-density mounting

Typical Applications

• Long distance transmission between the RTD and the

transmitter

• Combination with intrinsic safety barriers
