VT4500 Vibration Sensor

VT4500 Vibration Sensor

Monitor one direction vibration of motor & rotating equipment
Description
The VT4500 series vibration velocity transmitter sensors are designed with effective RMS vibration speed measurement capabilities. These sensors utilize the piezoelectric effect of piezoelectric crystals and incorporate solid-state charge amplifiers, precision integration processing, RMS conditioning units, and V-I conversion circuits. The vibration velocity signal is output via a 4-20mA transmitter conversion circuit.
In practical engineering applications, for the vibration protection of most rotating machinery, vibration velocity is often the preferred parameter to monitor. It can be quickly integrated into on-site control systems such as DCS and PLC. This product is specifically designed for precise vibration velocity measurement and offers wide frequency response, high accuracy, fast power-up and zeroing time, strong interference resistance, good airtightness, and long lifespan.

VT4500 Feature:
  • Precision Shear Mode Design of High-Performance Crystal Core: Ensures excellent low-frequency and temperature drift characteristics;
  • Two-Wire 4-20mA Loop Signal Output: Low system construction cost and stable operation;
  • Built-in EMC and Faraday Cage Shielding and Isolation Technology: Superior interference resistance;
  • High Signal-to-Noise Ratio and High Resolution;
  • Professional Aerospace Adhesive Technology: Ensures long product life;
  • Unique Precision Integration Conditioning Technology: Ensures short power-up and zeroing time;
  • Leading Professional Technology: Ensures stable and reliable performance.
