Product Description

The Bently Nevada 147M7136-02-01 is a high-performance, battery-powered wireless sensor designed for continuous monitoring of vibration and surface temperature on rotating machinery. Engineered for remote or challenging installations, it provides reliable condition monitoring without extensive cabling or infrastructure.

Integrated Sensing and Processing
This all-in-one unit captures tri-axial vibration (X, Y, Z) and surface temperature from a single mounting point. Onboard signal processing delivers overall vibration values, time waveforms, and frequency spectra, enabling early detection of mechanical faults.

Wireless Communication
Operates using the WirelessHART protocol, ensuring compatibility with existing industrial wireless networks. Mesh networking allows seamless integration with other WirelessHART instruments.

Rugged Industrial Design
Constructed with 316L stainless steel and high-performance PPS plastics, the sensor is IP67-rated for dust and moisture protection and certified for Class I, Division 1 hazardous environments.

Long-Term Operation
Optimized for low power consumption, the replaceable lithium-thionyl chloride battery can last up to five years depending on reporting intervals, making it ideal for long-term deployments.

Technical Specifications

Applications

Optimized for motors, fans, pumps, and small compressors, the 147M7136-02-01 is ideal for remote plant areas where wiring is challenging. Its diagnostic algorithms, including PeakDemod for early bearing defect detection, make it suitable for chemical, oil & gas, and power generation industries.

FAQ

Q: Can this sensor operate in extreme temperatures?
A: Yes, the sensor functions from -40°C to 85°C. Extended operation above 85°C will reduce battery life.

Q: How is it mounted?
A: Standard 1/4-28 UNF or M6x1 stud mounting allows secure attachment to machinery.

Q: What wireless protocol does it support?
A: WirelessHART for mesh networking with other industrial instruments.
