TM591-B00-G00 - Eddy Current Vibration Probe - Temp-Compensated IP67 Stainless Industrial Sensor

1. DIN-Rail Vibration Monitoring Solution Overview​

The ProvibTech TM591-B00-G00 is a compact vibration transmitter engineered for continuous machinery health monitoring in industrial automation systems. Featuring an ​integrated IEPE accelerometer (B00 suffix)​​ and ​4-20mA loop-powered output, this device measures velocity RMS (0-20mm/s) with ​​±1% accuracy​ across a ​10Hz–1kHz frequency range. Its ​anodized aluminum housing​ provides ​IP66 protection​ against dust and water jets, while ​DIN-rail mounting​ (per EN 60715) enables seamless integration into control panels. The "G00" designation denotes ​standard ISO 10816 frequency weighting. Operating across ​​-40°C to +85°C​ with ​ATEX/IECEx Zone 22 certification, it delivers predictive maintenance capabilities for pumps, motors, fans, and gearboxes in power generation, oil & gas, and manufacturing facilities. SIL 2 compliance per IEC 61508 ensures functional safety in critical applications.
