VSP004 is a submersible piezoelectric acceleration sensor for harsh environments. It provides a vibration range of -80…80 g and frequency response up to 12000 Hz. The sensor uses IEPE communication for connection to external VSE electronics. Its screened cable supports reliable vibration signal transmission. The design is intended for demanding and wet industrial installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VSP004 is designed for applications requiring high environmental protection. Its sealed construction supports submerged installation conditions. The sensor provides IP68 protection. The piezoelectric element delivers dynamic vibration information. This makes it suitable for machinery installed in wet environments.
The sensor measures vibration from -80 to +80 g. When connected to VSE electronics, the specified range is -50…50 g. Its frequency range extends from 1.5 to 12000 Hz. Noise density is specified at 0.1 mg. Single-axis measurement supports focused machine diagnostics.
VSP004 uses IEPE communication. The sensor operates with 10…12 V bias voltage. A screened cable connects the sensor to external diagnostic electronics. Reverse polarity protection is provided. This supports reliable installation in demanding vibration-monitoring systems.
