Product Overview
Optimized Sensor Mounting for Reliable Vibration Monitoring
Accurate vibration measurements depend heavily on proper sensor installation. The 37439-01 Mounting Base is engineered to isolate the accelerometer from base strain that can influence low-frequency vibration readings. By improving the mechanical coupling between the sensor and machine, the mounting base enhances measurement repeatability and overall monitoring reliability.
This accessory is commonly installed with compatible Bently Nevada accelerometers used on turbines, compressors, pumps, motors, gearboxes, and other critical rotating equipment.
