Product Details
RH103 / RH103T Industrial Piezoelectric Accelerometer IEPE Vibration Sensor for Predictive Maintenance & Condition Monitoring
Available at Mech Tech Global – Reliable, Robust, Reasonable
The RH103 / RH103T Accelerometer is a high-performance industrial vibration sensor designed for precision machinery condition monitoring and predictive maintenance applications. Built with IEPE (Integrated Electronics Piezo-Electric) circuitry, the sensor delivers stable, low-noise output and excellent frequency response across a wide range of industrial equipment including motors, fans, compressors, turbines, pumps, blowers, and rotating machinery.
Constructed using laser-sealed welding technology and 316L stainless steel, the RH103 series is engineered to withstand extreme industrial conditions including high temperature, moisture, shock, and corrosive environments. The MIL-CC-5015 military-grade connector ensures secure and reliable connectivity for long-term field installations.
The RH103T variant additionally features an integrated temperature measurement function, enabling simultaneous monitoring of both vibration and temperature for improved diagnostic capability.
