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 following
three 2-wire technology options are currently available:
• 4...20 mA
• 4...20 mA with 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 following temperature transmitters are currently available:
