Transmissor HART 2 Fios
Principais características

RTD, TC, Ohm, or mV input
Extremely high measurement accuracy
HART 5 protocol
Can be installed in Ex zone 0
1- or 2-channel version

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 channels to a digital 2-wire signal with HART communication.

Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without any distance between neighboring units, up to 84 channels can be mounted per meter.

DETALHES TÉCNICOS

Within a few seconds the user can program PR6335D 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 6335D 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.
