Pneumatic positioner Pneumatic positioner

AV1 Pneumatic positioner

Type AV Characterizable Pneumatic Positioners are control devices that satisfy a wide range of applications. They provide fast, sensitive, and accurate positioning of pneumatic signal or double-acting, linear or rotary motion actuators. A mechanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square root, linear, and square. The Type AV1 positioner receives an external pneumatic signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator.

  • Compact rugged design
  • High vibration and shock environments
  • Fast, accurate calibration
  • Single or double-acting without additional hardware
  • Vent design allows natural gas operation
  • Available with explosion-proof I/P converter

AV2 & AV3 Characterizable Electro-Pneumatic Positioners

Type AV2 & AV3 Characterizable Electro-Pneumatic Positioners are control devices that satisfy a wide range of applications. They provide fast, sensitive, and accurate positioning of pneumatic signal or double-acting, linear or rotary motion actuators. A mehanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square foot, linear, and square.

AV3 Characterizable Electro-Pneumatic Positioners

Type AV3 Characterizable Electro-Pneumatic Positioners are control devices that satisfy a wide range of applications. They provide fast, sensitive, and accurate positioning of pneumatic signal or double-acting, linear or rotary motion actuators. A mehanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square root, linear, and square. The positioners receive a current input (4 to 20 milliampere) from the control device and convert the signal to pneumatic signal. This pneumatic signal is converted to a pneumatic output that produces the motive force that positions the actuator. Type AV3 fails in place on loss of current input signal.

  • Compact rugged design
  • High vibration and shock environments
  • Fast, accurate calibration
  • Single or double-acting without additional hardware
  • Vent design allows natural gas operation
  • Available with explosion-proof I/P converter

 
abb Positioner & Converters ABB TZIDC

Positioner & Converters

The TZIDC represents the digital, intelligent positioner for communication via HART within the TZIDC positioner family. Unmatched shock and vibration immunity of 10g up to 80 Hz distinguishes the TZIDC from other‘s and guarantee reliable operation in almost all areas under harshest environmental conditions.

  • Digital communication acc. to HART
  • Easiest commissioning and operation on site due to local operation and auto adjustment
  • Intrinsically safe (IS)
  • Robust design and flexible in use with linear and rotaryactuators

 
abb Positioner & Converters ABB EDP 300

PositionMaster EDP300

The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities designed for mounting on pneumatic linear or part-turn actuators. It features an integral mount design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the positioner allow for considerable time savings as well as optimum control behavior. Because of its properties, the positioner is suited for even the most challenging operating conditions.

  • Stainless steel housing
  • Non-contact position sensor
  • High air capacity
  • Operation with natural gas
  • Extended diagnostics
