PR Electronics 6335D intrinsically safe HART 5 programmable temperature transmitter offers unrivalled performance in applications making heavy demands on accuracy to convert a wide array of input types to a 4 – 20 mA output signal. The 6335 transmitters provides unrivalled input versatility with galvanic isolation up to 1.5 kVAC. Virtually any thermocouple or 2, 3 & 4 Wire RTD, plus linear resistance and bipolar mV signals. Input sensor redundancy function maintains process availability and safety in the event of primary sensor failure.
The 6300 series transmitters are quickly and easily programmable to the specific application. Configuration via a standard PC and user-friendly software, PReset, available as a free download. Parameters for input, output, sensor error detection and process calibration can be configured via PReset within a few minutes.
