THE YT-1000 series positioner, mounted on a pneumatic actuator, moves the actuator by receiving dc 4-20ma signals from a controller. Also, the function of detecting and returning the actuator displacement provides accurate positioner in response to DC 4-20mA signals. The YT1000 series electro-pneumatic positioner can be used with both spring return and double acting actuators.
High anti-vibration (none effective in 5-200Hz).
The linking of air duct is perforated from, convenient for the linking in all direction.
Convenient for the transform of positive action and counteraction.
½ split range availability by simple adjustment without changing parts.
Simple structure for feedback connection.
Economically energy saving.
