What is a positioner?

Definition of positioner : one that positions especially : a mechanical device for placing or holding a body in position during an operation (as welding or drilling)

How does a positioner work?

The Positioner compares the forces generated by the control signal and the control valve stem through the motion connector and the feed back cam, and accordingly it feeds or bleeds the air going to the valve actuator. The instrument air signal is applied to the signal diaphragm.

How many types of positioner are there?

There are 3 primary types of positioners: Pneumatic Valve Positioner. Electro-Pneumatic (EP) Valve Positioner. Digital Valve Positioner.

Is positioner a word?

a person or thing that positions.

What are smart positioners?

Smart valve positioners are digital valve controllers, microprocessor-based, current to pneumatic instruments with internal logic capability. They are designed to convert a current signal to a pressure signal to operate a valve.

What is a positioner orthodontics?

A tooth positioner is used to control settling and to minimize or eliminate relapse of the teeth after an orthodontic treatment.

What does the actuator do?

An actuator is a device that uses a form of power to convert a control signal into mechanical motion. From electric door locks in automobiles, to ailerons on aircraft, actuators are all around us.

What is actuator and positioner?

A positioner may be used as a signal amplifier or booster. It accepts a low pressure air control signal and, by using its own higher pressure input, multiplies this to provide a higher pressure output air signal to the actuator diaphragm, if required, to ensure that the valve reaches the desired position.

How do you spell positioner?

What is the meaning of positioner?

Definition of positioner : one that positions especially : a mechanical device for placing or holding a body in position during an operation (as welding or drilling)

What is a valve positioner?

A valve positioner is a high-gain (0.5 to 10 percent proportional band), sensitive, proportional-only, valve-stroke position controller. Its set point is the control signal from the controller.

What do you mean by position?

The way in which something is placed: the position of the clock’s hands. b. The arrangement of body parts; posture: a standing position. c. In ballet, any of the five arrangements of the arms and feet in which the legs are turned out from the pelvis.

What is a smart digital positioner?

These smart digital positioners are communicating, microprocessor-based current-to-pneumatic instruments with internal logic capability. These are also capable of accommodating (rather integrating) a number of other accessories like solenoid valves, pressure switches, etc.
