VSM101 is a three-axis MEMS acceleration sensor for industrial vibration measurement. It measures vibration from -40 to +40 g across a frequency range up to 4500 Hz. The sensor uses an IEPE interface for connection to external diagnostic electronics. Its stainless-steel housing provides high environmental and mechanical resistance. Shielded PUR cabling supports industrial installation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VSM101 measures vibration along three measurement axes. The capacitive MEMS principle provides stable dynamic measurement. Its sensitivity is 100 mV/g. The sensor supports machine vibration analysis in multiple directions. This is useful where radial and axial vibration information is required.
The sensor uses a stainless-steel housing for demanding environments. IP67, IP68 and IP69K protection support harsh installations. The sensor withstands 50 g mechanical shock. Drag-chain suitability supports moving-cable installations. The supplied M5 mounting screw simplifies mechanical installation.
VSM101 communicates using an IEPE signal interface. The sensor operates with 11…16 V bias voltage. Its 3 m PUR shielded cable supports connection to external evaluation electronics. A self-test line enables functional checking through compatible diagnostic electronics. This makes the sensor suitable for predictive-maintenance systems.
