Measuring system
Application range Temperature, resistance or voltage measurements of solids, liquids and
gases in industrial environment.
Design
Versions Versions Versions Versions
TT 50 C In-head transmitter which is intended for installation in a "B connection
head" or larger according to DIN 43729.
This transmitter is optionally available in an intrinsically safe version for
installation in potentially explosive areas (TT 50 C Ex).
TT 50 R Rail-mount transmitter which is intended for installation on a top-hat rail
according to DIN 50022 / EN 60715.
Features Features Features Features
HART ® 5 compliance The transmitter are fully compliant with the HART ® 5 protocol. HART ® 5
offers the possibility to receive diagnostic information such as sensor errors
or sensor conditions.
Sensor isolation monitoring The isolation resistance of thermocouples and RTD’s as well as the cabling
between sensor and transmitter is being monitored. If the isolation is below
a user-defined level, this will be indicated in ConSoft and with a diagnostic
HART
® message, and the output signal can be forced upscale or downscale.
This feature requires an extra lead inside the thermocouple or RTD.
Customized linearization For resistance and mV inputs, the 50-point customized linearization can
provide a correct process value, in a choice of engineering units, for a sensor
with non-linear input/output relation.
Sensor break monitoring User-definable output: 3.6...22.8 mA.
