PR 6335 2-wire HART Transmitter

The PR 6335 2-wire HART Transmitter is a high-performance industrial temperature transmitter for precise temperature and resistance signal conversion in advanced process automation systems. The 6335 Series, from PR electronics, supports RTD (Pt100-Pt1000, Ni100-Ni1000), thermocouple (TC), linear resistance, as well as mV inputs. Furthermore, this versatile transmitter converts sensor signals into a standardized 4-20 mA output with integrated HART communication for efficient monitoring and control.

• Linearized temperature measurement with Pt100-Pt1000, Ni100-Ni1000, as well as TC sensors. 
• Difference or average temperature measurement of 2 resistance (RTD) or TC sensors.
• Conversion of linear resistance variation to a standard analog current signal, for example, 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.
• Models in the 6335 Series are intrinsically safe, galvanically isolated, and feature various certifications for use in hazardous areas.
• Model PR 6335A has certification for mounting in Zone 2 and 22 / Class I, Div 2, Groups A, B, C, D.
• Model PR 6335D has certification for mounting in Zone 0, 1, 2, 21, 22, M1 / Class I, II, III, Div 1, Groups A, B, C, D.
