Product Overview
The Bently Nevada 70M301 is a Ranger Pro single-axis wireless vibration sensor for monitoring the condition of industrial rotating machinery. It combines vibration sensing with wireless data transmission, allowing machinery condition information to be collected without running a dedicated signal cable from every measurement point back to a monitoring cabinet.
The sensor is suited to distributed monitoring points on equipment such as pumps, motors, compressors, fans, gearboxes, and other rotating assets. A wireless architecture is particularly useful when many machines need to be monitored across a large plant or when conventional wired instrumentation would require extensive cabling.
Because the 70M301 measures vibration along a single axis, its installation orientation should correspond to the machinery condition parameter being monitored. Correct mounting location and mechanical coupling have a direct effect on the usefulness of the collected vibration data.

Working Principle
The 70M301 detects mechanical vibration at the installed machinery location and converts the measured vibration into monitoring data for wireless transmission.
A typical signal path is:
Rotating Machinery → 70M301 Vibration Sensor → Ranger Pro Wireless Network → Monitoring System
The sensor measures vibration along its single sensing axis. Mechanical coupling between the sensor and machine surface is therefore important. The mounting position should be selected according to the bearing location, machine structure, expected vibration direction, and the condition parameter being investigated.
After acquisition, the measurement data is transmitted through the Ranger Pro wireless architecture. The sensor itself performs the field measurement, while the wireless network provides the communication path toward the monitoring and analysis environment.
Role in a Ranger Pro Wireless Monitoring Architecture
The 70M301 operates at the field sensing layer of the Ranger Pro monitoring architecture. It provides a wireless measurement point directly on the monitored machinery and sends vibration information into the wireless monitoring network.
| System Element | Function |
|---|---|
| Rotating Machinery | Generates mechanical vibration associated with operating condition |
| 70M301 Wireless Vibration Sensor | Measures vibration along a single axis and transmits monitoring data wirelessly |
| Ranger Pro Wireless Network | Provides the communication path for wireless sensor data |
| 70M300 Wireless Repeater | Can extend the wireless communication path where additional network coverage is required |
| Wireless Network Infrastructure | Collects and transfers monitoring information toward higher-level systems |
| Monitoring / Analytics Software | Displays, trends, and analyzes collected machinery condition data |
The sensor is normally installed close to the machinery feature being monitored. Wireless communication considerations should then be evaluated separately from mechanical measurement considerations.
Industrial Applications
| Application | Typical Use |
|---|---|
| Pump Monitoring | Monitors vibration at pump bearing or housing locations |
| Motor Monitoring | Provides wireless vibration measurements for industrial motors |
| Compressor Monitoring | Supports condition monitoring of compressor rotating assemblies |
| Fan and Blower Monitoring | Detects changes in vibration associated with rotating fan and blower equipment |
| Gearbox Monitoring | Provides vibration data from gearbox housings and bearing locations |
| Oil and Gas Facilities | Supports distributed wireless monitoring across production and process equipment |
| Chemical Processing | Reduces cabling requirements for vibration monitoring across process machinery |
| General Rotating Equipment | Provides additional wireless vibration measurement points for condition-based maintenance |
Installation and Maintenance
- Select the Measurement Point — Install the sensor at a mechanically meaningful location, typically near the bearing or machine structure associated with the condition being monitored.
- Orient the Sensor Correctly — Because the 70M301 uses a single-axis measurement configuration, align its sensing axis with the vibration direction of interest.
- Prepare the Mounting Surface — Ensure the mounting surface provides appropriate mechanical contact and is free from contamination that could affect sensor coupling.
- Secure the Sensor Properly — Use the applicable mounting method and ensure that the sensor remains firmly coupled to the machinery during operation.
- Consider Machine Operating Conditions — Select a location that represents the machinery condition without unnecessarily exposing the sensor to avoidable mechanical or environmental stress.
- Verify Wireless Coverage — Confirm that the installed sensor can communicate with the Ranger Pro wireless network from its final operating position.
- Use a Repeater When Required — If the sensor location has insufficient wireless coverage, evaluate the use of an appropriate wireless repeater such as the 70M300.
- Check the Initial Measurement — After installation, review the vibration data to confirm that the sensor is producing a plausible measurement for the selected machine location.
- Establish a Baseline — Record normal operating vibration behavior so that future changes can be compared against an established condition.
- Inspect the Mounting Point During Maintenance — Check for looseness, mechanical damage, corrosion, or changes to the mounting surface that could affect measurement quality.
- Separate Measurement and Communication Faults — If data is missing, determine whether the issue is related to vibration sensing, sensor installation, wireless communication, or the wider network.
- Follow Site Safety Procedures — Perform installation and maintenance according to applicable machinery isolation, electrical, process, and wireless equipment safety requirements.
For troubleshooting, compare the problem with the sensor’s physical installation and network status. An abnormal vibration trend with normal communication may indicate a genuine machinery condition or mounting issue, while missing data should first prompt an inspection of the wireless communication path and sensor connectivity.

Technical FAQs
What type of measurement does the Bently Nevada 70M301 provide?
The 70M301 is a single-axis wireless vibration sensor. It measures vibration at the installed machinery location and transmits the resulting monitoring information through the Ranger Pro wireless network.
Why is sensor orientation important for the 70M301?
The 70M301 measures vibration along a single axis. Its orientation therefore determines which vibration direction is being monitored. The sensing axis should be aligned with the mechanical direction or machine feature relevant to the monitoring objective.
Where is the 70M301 typically installed on rotating equipment?
Typical locations include bearing housings, motor structures, pump housings, compressor assemblies, fan structures, and gearbox housings. The exact measurement point should be selected according to the machine construction and the condition being monitored.
What should be checked if the 70M301 stops transmitting vibration data?
Check the sensor installation, wireless network coverage, communication path, and associated Ranger Pro network infrastructure. If the wireless connection is available but the vibration data appears abnormal, inspect the mounting condition and measurement orientation before assuming a sensor failure.
