AV1 Pneumatic positionerType 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.

AV2 & AV3 Characterizable Electro-Pneumatic PositionersType 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 PositionersType 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.

Positioner & ConvertersThe 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.

PositionMaster EDP300The 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.
