Head-mounted and rail-mounted transmitters both convert the temperature sensor's small
signal into a standardised output signal of 4...20 mA, not susceptible to interference, or into a
digital signal. The output signal depends on the type of temperature transmitter, the
manufacturer currently offers three different technologies:
• Two-wire technology with 4...20 mA
• HART ®
• Profibus-PA
You can parameterise almost any temperature transmitter using a PC and a computer program.
The only exceptions are the TT 10 C/R and TT 11 C/R versions, whose measuring ranges must be
set using solder bridges. The manufacturer offers the following temperature transmitters:
Available in both head-mounted and rail-
mounted version Only available in rail-mounted version
TT 10 C/R (analogue, standard) TT 31 R (one or two-channel)
TT 11 C/R (analogue, 3-wire circuit) TT 32 R
TT 20 C/R (analogue)
TT 30 C/R (digital, standard)
TT 40 C/R (digital, precise)
TT 50 C/R (digital, HART ® )
TT 51 C/R (digital, HART ® , SIL2)
TT 60 C/R (digital, Profibus-PA)
INFORMATION!
Consult the relevant transmitter handbook for more detailed information on the temperature
transmitters.
