Fisher Pneumatic Positioner

Traditional pneumatic locators receive pneumatic control signals and convert them into corresponding pneumatic output signals that are sent to the control valve actuator. This positioning technology has always been an evergreen tree in the process control industry, and it has been widely used for decades. We have manufactured various Fisher products ® Pneumatic locators can almost meet all the needs of customers.

Fisher ® 3570Fisher Pneumatic Positioner

Fisher ® The 3570 pneumatic valve positioner is used in conjunction with the control valve assembly to provide accurate valve stem position proportional to the input signal received from the control device. The input signal range can be 0.2 to 1.0 bar (3 to 15 PSI), 0.4 to 2.0 bar (6 to 30 PSI), or other required pneumatic input signal ranges. These locators are typically used in conjunction with pneumatic piston actuators. However, the 3570 series products can be used in conjunction with pneumatic, long stroke, cylinder actuators, or pneumatic diaphragm actuators.

1. The adjustable ratio -3570 series locator has split range control function.

2. The control valve diagnostic testing function - {sp} should support the FlowScanner valve diagnostic system for valve/actuator/positioner diagnostic testing, and can install connectors, pipelines, and other components between the 3570 series positioner and actuator.

3. Universality - These locators are typically used in conjunction with pneumatic piston actuators. However, some types of products within the 3570 series can be used in conjunction with pneumatic, long stroke, cylinder actuators, or pneumatic diaphragm actuators.
