Vibration transmitters in 4-20 mA 2-wire technology

Vibration transmitters in 4–20 mA 2-wire technology – Reliable monitoring for critical machines

Vibration transmitters with 4–20 mA output in 2-wire technology are the first choice when it comes to continuous condition monitoring of rotating machines. They convert the measured vibration velocity or acceleration directly into a standardised current signal (4–20 mA) – robust, interference-free and compatible with common process control systems.

Special features and technical advantages

• Direct 4–20 mA signal: Enables easy integration into PLC, DCS or SCADA systems without additional signal conditioning.
• 2-wire technology: Power supply and signal transmission via a single cable – reduces cabling effort and installation costs.
• Robust design:
  Developed for harsh industrial environments: vibration-proof, shock-resistant and with a high degree of protection (IP67 or higher).
• Linearity and accuracy: Precise measurement of vibration velocity (mm/s) or acceleration (g) in defined frequency ranges according to ISO 10816.
• Optional temperature compensation: Ensures accurate measurements even with large temperature fluctuations.

Typical areas of application

• Condition monitoring of pumps, motors and compressors
• Early detection of bearing damage or imbalances.
• Predictive maintenance in the process industry
• Seamless integration into existing monitoring systems for continuous plant availability.
• Power plants and energy facilities
• Protection against unplanned downtime through reliable vibration diagnosis.
• Chemical industry and refineries
• Available as an ATEX option for potentially explosive atmospheres.
