Smart Positioners
Rotex Smart Positioners
Rotex Smart Positioner is designed to meet your most basic to advanced needs, with an adaptive PID loop which helps ensure high accuracy, lower dead band and extremely steady performance of the positioner.
Innovative Features of Rotex Smart Positioners
LCD DISPLAY
- Large LCD display for readability.
- No abbreviation or short form used.
- On-screen display of diagnostics, alarms and error messages.
- Structured menu for parameters, setups and diagnostics.
SUPERIOR FUNCTIONALITY
- Contactless feedback, with patented algorithm.
- Blind Mount™ , eliminates the need to orient mounting angle.
MODULAR DESIGN WITH ENCAPSULATED ELECTRONICS
- Fewer modules makes it easy to install, operate and maintain.
- Fewer number of internal components and moving parts, increased reliability and life span.
- Pre-fitted gauges, enclosed in IP66 enclosure ensure lifetime guarantee and reliability.
- Encapsulated electronics provide protection against moisture and humidity, avoiding failure of electronics.
PRECISERVO™
- Has built – in feedback sensor.
- Can accommodate wide variety of actuator volumes without need of flow control valve or volume booster.
- Metal-to-metal contact, low friction and high sensitivity.
