VSP02A is an ATEX piezoelectric acceleration sensor for hazardous-area vibration monitoring. It provides a -50…50 g measuring range and 2…10000 Hz frequency response. The sensor uses IEPE communication and intrinsically safe supply arrangements. Stainless-steel construction provides mechanical robustness. It is designed for connection to external VSExxx diagnostic electronics.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VSP02A is designed for vibration measurement in potentially explosive environments. ATEX and IECEx certification support specified hazardous-area installations. The sensor connects through intrinsically safe supply isolators. Its single-axis design provides focused vibration measurement. This supports condition monitoring of critical equipment.
The sensor measures vibration from -50 to +50 g. Its operating frequency range is 2…10000 Hz. Sensitivity is 100 mV/g. Noise density is 0.1 mg. The piezoelectric sensing principle provides dynamic vibration information.
VSP02A uses a robust stainless-steel housing. Its IP68 protection supports harsh environments. The sensor operates across -55…90 °C. M8 × 1.25 mounting enables secure installation. A 5000 g shock rating supports demanding applications.
