Features:

  • Total Ground Loop Elimination
  • Extended Transmission Capability
  • Legacy System Sustainability
The Vibro-Meter GSI130-244-130-000-204 actively breaks the physical electrical path between the sensor and the monitor. This eliminates errors caused by stray currents and potential differences in the grounding system, ensuring that your vibration data reflects machine health, not electrical noise.

Replacing passive Zener barriers that restrict cable length, the Vibro-Meter GSI130-244-130-000-204 actively drives the signal. This allows operators to place sensors in hazardous areas while locating the processing electronics hundreds of meters away in a safe, climate-controlled environment without signal degradation.

As a direct replacement for discontinued modules, the Vibro-Meter GSI130-244-130-000-204 allows facilities to maintain their existing TSI racks. It ensures "form, fit, and function" compatibility, eliminating the need for costly control system migrations or re-certification of safety loops.

The GSI130-244-130-000-204 Vibro-Meter Galvanic Separation Unit / Signal Isolator may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Heavy-Duty Gas & Steam Turbines: The Vibro-Meter GSI130-244-130-000-204 is heavily utilized in power generation facilities to monitor critical turbine shaft vibration, ensuring early detection of rotor unbalance or structural misalignment.
  • Petrochemical Centrifugal Compressors: Installed in oil and gas refineries where explosive gases are constantly present, this unit safely monitors axial thrust displacement to prevent catastrophic impeller-to-casing contact.
  • Large Industrial Pumps & Fans: Protects high-capacity cooling water pumps and forced-draft fans in heavy processing plants by ensuring accurate speed and vibration feedback under continuous operation.
  • Hydroelectric Power Generators: Ideal for monitoring low-frequency vibrations and structural movements in hydro-turbines, where water-induced low-frequency dynamics require absolute signal precision.
  • Hazardous Industrial Atmospheres: Optimized for Zone 0, 1, and 2 environments, the Vibro-Meter GSI130-244-130-000-204 acts as a robust barrier preventing any electrical spark from reaching volatile gases.
  • High Electromagnetic Interference (EMI) Zones: Specifically engineered to operate inside power plant cabinets surrounded by high-voltage switchgear, variable frequency drives (VFDs), and heavy generators without signal distortion.
  • Extreme Temperature Resilience: Capable of maintaining tight calibration and minimal thermal drift even when installed in field marshaling kiosks subjected to seasonal ambient fluctuations.
  • High-Density Enclosures: Its slim 17.5 mm (approximate standard format) or compact modular casing allows multiple Vibro-Meter GSI130-244-130-000-204 units to be stacked tightly on a single DIN rail, optimizing space in crowded control rooms.
  • Ultra-Low Signal Attenuation: The Vibro-Meter GSI130-244-130-000-204 guarantees an exceptionally linear transfer ratio, meaning the precision of the micro-inch shaft displacement captured by the probe is preserved entirely at the receiver end.
  • Zero-Latency Analog Processing: Without any digital-to-analog conversion steps, the Vibro-Meter GSI130-244-130-000-204 delivers real-time data transmission, crucial for emergency over-speed or high-vibration trip systems where milliseconds matter.
  • High Galvanic Isolation Rating: Features a robust test isolation rating up to 4 kVAC, protecting expensive backend data acquisition systems (DCS/PLC) from severe lightning strikes or field-side short circuits.
  • Long-Term Calibration Stability: Built with premium-grade, low-tolerance electronic components, the Vibro-Meter GSI130-244-130-000-204 minimizes drift over decades of operation, drastically reducing the frequency and cost of scheduled maintenance shutdowns.
Description
The GSI130-244-130-000-204 is a galvanic separation unit designed for vibration monitoring and long-distance signal transmission. This unit is both CENELEC / PTB approved and CSA approved, ensuring compliance with strict safety and industrial standards.

The GSI130-244-130-000-204 is used for supplying transducers and conditioners, as well as for reading the signals they generate. It is suitable for 2-wire transmission systems and, more generally, for any electronic system with a current consumption of less than 20 mA. The unit outputs a voltage signal proportional to the current consumed by the conditioner, providing a direct and reliable signal for analysis.

Furthermore, the Vibro-Meter GSI130-244-130-000-204 simplifies safety compliance by removing the need for bulky Zener barriers. Unlike passive barriers that introduce voltage drops and limit line length, this active isolator maintains signal dynamics over long transmission distances, making it ideal for power generation and oil & gas facilities.
