PR electronics 2-wire HART® Transmitter 6335D

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 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. Technical characteristics 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. Mounting / installation 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. NB: As Ex barrier we recommend 5106B.
