Barksdale XT, XTi User Manual
Index: B / 923-1884
Transmitters for bypass level indicators
Features / Description
The measuring principle and construction of this series are identical to those
of the XM series, however the XT series is equipped with a 2-wire transmitter
module (instead of simple terminals in the KLS terminal box). This transmitter
module (transducer) converts the resistance into a 4...20 mA output signal.
For e.g. interface measurement the output signal can also be inverted (20...4
mA). A version with linearisation of the tank content graph is available as an
option.
Two versions are available:
XT - Standard version
XTi - EEx i for intrinsically safe applications
Transmitter XT with type MU3L, circuit monitoring with selective fault
recognition and selective output control (Namur NE43) 3.5 mA or
23 mA, reversed polarity protection.
Transmitter XTi with type MUEX, intrinsically safe transmitter module with
ATEX approval EEx ia IIC T1...T6, reversed polarity protection and fault
recognition with selective output control (Namur NE 43) 3.5 mA or 23 mA.
