VISÃO GERAL

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 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.

For DIN form B sensor head or DIN rail mounting with the PR fitting type 8421.

DETALHES TÉCNICOS

Within a few seconds the user can program PR5335A 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 5335A has been designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.

Continuous check of vital stored data for safety reasons.

Sensor error detection according to the guidelines in NAMUR NE89.
