Product Overview
The BENTLY NEVADA 23732-01 is a precision piezoelectric accelerometer sensor probe engineered for continuous condition monitoring and protection of rotating machinery in industrial environments. As a core component within the Bently Nevada vibration monitoring ecosystem, the Bently Nevada 23732-01 converts mechanical vibration acceleration into a proportional electrical signal, enabling real-time assessment of equipment health and early detection of developing faults. This accelerometer is widely deployed across power generation, oil and gas, and heavy manufacturing applications where machinery reliability is critical.
The 23732-01 Bently Nevada employs a piezoelectric sensing element that generates an electrical charge proportional to the acceleration exerted upon it, leveraging the direct piezoelectric effect for accurate vibration measurement . The sensor features a sensitivity of 25 mV/g with a nominal conversion coefficient of 10.2 mV/(m·s⁻²), providing high-resolution signal output suitable for both protection systems and diagnostic analysis . Its split housing design separates the sensing element from the electronics block, enhancing thermal isolation and allowing the sensor to operate reliably across a wide temperature range from -29°C to +121°C .
Functionally, the BENTLY NEVADA 23732-01 serves as the primary sensing element in machinery protection and condition monitoring systems, feeding acceleration data to monitors that evaluate vibration severity against alarm thresholds. With a frequency response spanning 10 Hz to 20 kHz (±3 dB) and a mounted resonant frequency of 30 kHz minimum, the sensor captures both low-frequency rotor dynamics and high-frequency bearing defect signatures . For facilities operating gas turbines, compressors, and large motors, the 23732-01 Bently Nevada represents a proven sensing solution that supports predictive maintenance strategies and prevents unplanned downtime.
