Frequently Answers and Questions

What is the operating principle of the RTX-1000R series?
The RTX-1000R series operates based on the principle of converting an electrical input signal (4-20mA) into a pneumatic output signal. As the input signal increases, the flapper (2) in the positioner moves closer to the nozzle (3), increasing the air pressure supplied to the actuator (10). This movement is then transmitted to the cam (16) and finally controls the valve position.
What is the supply pressure range for the RTX-1000R series?
The RTX-1000R series requires a supply pressure range of 1.4 ~ 8.0 kgf/cm² (20 ~ 120psi). This pressure is used to operate the internal components of the positioner and drive the actuator.
What are the adjustment options available for the RTX-1000R series?
The RTX-1000R series offers several adjustments for fine-tuning its performance. These include zero point adjustment, span adjustment, A/M switch (Automatic/Manual) adjustment, seat adjuster, and orifice adjustment. These adjustments allow for tailored operation based on the specific application and requirements.
