The PR 6333 2-wire Programmable Transmitter is a high-accuracy industrial temperature and resistance transmitter for modern process control and automation systems. This versatile DIN-rail temperature transmitter supports RTD (Pt100-Pt1000, Ni100-Ni1000) and linear resistance input, thus delivering precise, linearized 4-20 mA output signals compatible with PLCs, SCADA, and DCS platforms. With programmable settings and a robust design, the 6333 Series, from PR electronics, is ideal for demanding temperature measurement, level sensing, and position feedback in manufacturing, energy, and industrial applications.
- Linearized temperature measurement with Pt100-Pt1000 or Ni100-Ni1000 sensor.
- Conversion of linear resistance variation to a standard analog current signal, for example, from valves or Ohmic level sensors.
- Models in the 6333 Series are intrinsically safe and feature various certifications for use in hazardous areas.
- Model PR 6333A has certification for mounting in Zone 2 and 22 / Class I, Div 2, Groups A, B, C, D.
- Model PR 6333B has certification for mounting in Zone 0, 1, 2, 21, 22, M1 / Class I, Div 1, Groups A, B, C, D.
PR 6333 2-wire Programmable Transmitter from PR electronics
