2-WIRE TRANSMITTER
WITH HART
PRetop 5335
• RTD, TC, Ohm, or mV input
• Extremely high measurement accuracy
®
• HART
communication
• Galvanic isolation
• For DIN form B sensor head mounting
Application:
• Linearised 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 analogue current
signal, for instance from valves or Ohmic level sensors.
• Amplification of a bipolar mV signal to a 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 PR5335 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.
• Continuous check of vital stored data for safety reasons.
• Sensor error detection according to the guidelines in NAMUR NE 89.
Mounting / installation:
• For DIN form B sensor head mounting. In non-hazardous areas the 5335 can
be mounted on a DIN rail with a special fitting.
• NB: As Ex barrier for 5335B, C and D we recommend 5106B.
