Overview

The VIBRO-METER 110-210-000-033 refers specifically to the CV210 Velocity Transducer System, a precision sensor assembly optimized for low-frequency vibration measurement. This system is essential for monitoring absolute vibration in slow-speed machinery such as hydro-turbines, large pumps, and industrial gearboxes. It operates on the moving coil / permanent magnet principle, generating a signal proportional to vibration velocity without requiring external power.

Its rugged construction, stainless-steel body, and hermetically sealed IP68 enclosure make it ideal for damp, corrosive, or submerged environments. Therefore, it plays a critical role in machinery health programs focused on early detection of faults in slow-speed rotating assets.
This part number is commonly supplied with the IVC 632 signal conditioner, which enhances low-frequency performance and facilitates long-distance signal transmission.

Technical Data

Precision and environmental durability define the performance of the CV210 transducer. The table below summarizes the core specifications for CV210 P/N 110-210-000-033.

Typical Applications

The CV210 110-210-000-033 is specifically designed for low-speed rotating equipment, typically operating between 60–1000 RPM. Key application areas include:

• Hydraulic Turbomachinery
  Kaplan and Francis turbines in hydropower facilities, where low-frequency vibration dominates.

• Pulp & Paper Mills
  Monitoring large centrifugal pumps and slow-speed gearboxes.

• Submerged or Harsh Environments
  Ideal for large fans, agitators, and industrial equipment exposed to moisture or corrosive media.

Therefore, the CV210 enables accurate detection of common faults such as unbalance, misalignment, looseness, and bearing degradation at very low rotation speeds.

FAQ: VIBRO-METER CV210 (110-210-000-033)

Q1: Why is the CV210 sensor suitable for low-frequency vibration measurement?

A1: The CV210 is engineered for low-frequency response and, when paired with the IVC 632 signal conditioner, it achieves accurate measurement down to 0.5 Hz. This low-frequency capability is essential for diagnosing issues in slow-speed rotating machinery where vibration energy is concentrated at lower frequencies.

Q2: Does the CV210 require external power to operate?

A2: No. The CV210 is a self-generating velocity transducer. Its moving coil and permanent magnet assembly produces a voltage signal proportional to vibration velocity through electromagnetic induction. This passive operation simplifies wiring, enhances reliability, and supports use in hazardous environments.

Q3: What is the purpose of the IVC 632 signal conditioner?

A3: The IVC 632 processes and conditions the raw signal from the CV210. Its functions include:

• Low-frequency compensation (down to 0.5 Hz)

• Converting the sensor output to voltage or 4–20 mA current

• Ensuring stable, noise-immune transmission over distances up to 1000 meters

• Providing galvanic isolation for improved safety
