Electo Pneumatic Transducer

The electro-pneumatic transducer PT500 series provides the proportional conversion from a 4...20 mA input signal to a 0...100% supply pressure output signal. The PT500 is the preceding-model of the current Tranducer PT700.


  • Accurate conversion of the electrical input signal by using a silicium pressure sensor for feedback
  • Robust modular design
  • Pressure regulator eliminates variations in supply air pressure
  • Innovative, reliable transducer technology (piezo electric microvalve)
  • Input signal: 4...20mA Split range start: 4 mA or 12 mA
  • High resistance against shock and vibration
  • Two wire system for signal and power supply line
  • Easy maintenance due to modular design
  • Available Options:
  • milliammeter (input signal display)
  • Universal mounting kit according to NAMUR specifications in stainless steel
  • Precise control performance and high dynamic behaviour with PI control characteristics in the internal control loop
