Dual-Axis Vibration Transmitter Modbus RTU IP68 ATEX Certified

The ProvibTech TM0181-A80-B00 is an advanced dual-axis vibration transmitter engineered for comprehensive machinery health monitoring in industrial automation. Featuring Modbus RTU output (A80 designation) and integrated piezoelectric sensors (B00 suffix), this device simultaneously measures vibration velocity (RMS/Peak) on two orthogonal axes (X/Y) with ±1% accuracy. Its 316L stainless steel housing provides IP68/IP69K protection against dust, high-pressure washdowns, and temporary submersion. Operating across -40°C to +85°C with ATEX/IECEx Zone 22 certification, it delivers frequency-weighted measurements per ISO 10816 standards. The compact design incorporates dual IEPE sensors with 4kHz bandwidth, enabling real-time monitoring of pumps, motors, gearboxes, and other rotating equipment in power generation, oil & gas, and manufacturing facilities where multi-axis analysis is critical for predictive maintenance.
