Product Overview
The Yokogawa ASR133 is an industrial RTD and potentiometer input module designed for distributed control systems (DCS). It is used to acquire resistance-based signals from field devices such as RTD temperature sensors and potentiometers, then convert them into digital data for process monitoring and control.
This module is designed for high-accuracy measurement in industrial environments and integrates into Yokogawa control platforms for stable and reliable process data acquisition.

Function and Working Principle
The ASR133 module measures resistance changes from RTD sensors or potentiometers and converts them into digital signals for the control system.
For RTDs, the resistance varies with temperature, allowing accurate temperature measurement. For potentiometers, resistance variation represents position or mechanical movement.
The module performs internal signal conditioning and conversion, ensuring stable measurement even in electrically noisy industrial environments.
This enables:
- Accurate temperature measurement from RTDs
- Position feedback from potentiometers
- Stable resistance-to-digital conversion
- Integration with DCS control systems
- Reliable industrial signal acquisition
Role in Industrial Automation Systems
The ASR133 module is used in process automation systems where precise measurement of temperature or mechanical position is required. It supports:
- Distributed Control Systems (DCS)
- Process monitoring systems
- Industrial instrumentation networks
- Temperature control loops
- Mechanical position feedback systems
It ensures accurate field data acquisition for stable process control.
