ELECTROPNEUMATIC POSITIONER RTX 1000

Special low pressure diaphragm direct acting valve ensures quick and precise response to minor changes in signal pressure

Low hysteresis increases overall efficiency

Excellent performance under vibration up to 4g (3mm amplitude)

High life of diaphragm and zero maintenance

Compact design, rugged construction with a rigid ISO 5211 mounting

Wide range of zero and span adjustment for easy and precise calibration

Stable, fast and accurate response with change in supply pressure due to unique poppet and diaphragm valve design

All internal parts are hard anodized

Split range control can be easily adopted by change in few internal parts

Simple to convert from direct acting to reverse acting or vice versa

Orifice option prevents from hunting and also for controlling speed

Bright visual indicator on both flat and high dome type positioners

Internal and external mounting of the position transmitter and limit switch available

Internal circuit of the positioner is highly corrosion resistant as no part (metal plate) is exposed

IP 66 protection

CE certified
