Features:
• RTD, TC, Ohm, or mV input
• Extremely high measurement accuracy
• HART 5 protocol
• Programmable sensor error value
• For DIN form B sensor head mounting

Application:
• Linearized temperature measurement with Pt100...Pt1000,
Ni100...Ni1000, or TC sensor
• Difference or average temperature measurement of 2
resistance or TC sensors
• Conversion of linear resistance variation to a standard
analog current signal, for instance from valves or Ohmic
level sensors
• Amplification of bipolar mV signals to standard 4...20 mA
current signal
• Connection of up to 15 transmitters to a digital 2-wire
signal with HART communication

Technical characteristics
• Within a few seconds the user can program TT5335A to
measure temperatures within all ranges defined by the
norms
• The RTD and resistance inputs have cable compensation
for 2-, 3– and 4-wire connection
• The TT5335A has been designed according to strict safety
requirements and is therefore suitable for application in SIL
2 installments
• Continuous check of vital stored data for safety reasons
• Sensor error detection according to the guidelines in
