TXR-72915-M1311 - Eddy Current Vibration Probe - 15mV/mm/s IP67 Stainless M13 Industrial Sensor

​1. Military-Grade Triaxial Vibration Sensor Overview​

The ProvibTech TXR-72915-M1311 is a ruggedized triaxial accelerometer engineered for mission-critical applications in extreme industrial and defense environments. Featuring a ​hermetically sealed titanium housing (MIL-T-9046J)​​ with ​integral mineral-insulated cable, this sensor delivers ​​±100g range per axis​ with ​50mV/g sensitivity​ and ​​<1% cross-axis sensitivity. Its ​M1311 suffix​ denotes a ​MIL-C-5015 connector​ with ​environmental sealing per MIL-STD-810H. Operating continuously at ​​+150°C​ (peak ​​+300°C), it achieves ​IP69K protection​ against 150-bar steam jets and ​chemical resistance to MIL-HDBK-454 fluids. Certified for ​ATEX/IECEx Zone 0​ and ​SIL 3 compliance, it incorporates ​TEDS memory​ and ​phase-matched channels (±0.5°)​​ for precision vibration analysis in rocket testing, armored vehicle monitoring, and nuclear power applications where failure is not an option.
