• Frequency Response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB; 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Broadband: 0.229 mm/s (0.009 in/s) pk.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain).
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no degradation of signal.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F).
• Shock Limit: 5000 g pk, maximum.
• Humidity Limit: 100% condensing, non-submerged.

• Weight: <297 g (10.5 oz.), typical.
• Mounting Surface: 33 mm diameter (1.3 in diameter).
• Height: 82 mm (3.2 in).
• Case Material: 316L stainless steel.
• Connector: 2-pin 316L stainless steel MIL-C5015, top.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).
• Polarity: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer.
• Mounting Angle: Any orientation.

One distinctive aspect is the broadband performance of 0.229 mm/s pk, which ensures that even low-level vibrations are detected, enabling early intervention before minor issues escalate into major failures.

Applications and Use Cases

The 190501-07-00-01 is ideal for vibration monitoring on pumps, fans, compressors, and other rotating equipment. Its intrinsic safety approvals (CSA/NRTL/C Class I, Division 1; ATEX/IECEx/CSA Class I, Zone 0/1) make it suitable for hazardous areas where flammable gases or vapors may be present. The transducer's wide frequency response and high shock limit allow it to perform reliably in heavy industrial environments, from petrochemical plants to power generation facilities.

Installation and Setup

Proper installation is crucial for accurate vibration measurement. The 190501-07-00-01 features a plate stud mounting option (3/8-in 24 to 3/8-in 24) and a MIL-C-5015 connection interface. Ensure the mounting surface is clean and flat, and apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to secure the transducer. The transducer can be mounted in any orientation, providing flexibility in tight spaces. For optimal signal integrity, use the specified cable (part number 02173006) up to 305 meters without signal degradation.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is recommended to ensure long-term reliability. Check for any signs of physical damage or corrosion, especially in harsh environments. The 316L stainless steel case offers excellent resistance to corrosion, and the internal electronics are isolated from the case, reducing the risk of ground loops. Periodic verification of the output bias voltage (10.1 Vdc ± 1.0 Vdc) can help confirm proper operation. Always follow the manufacturer's guidelines for maintenance and troubleshooting.

Compatibility and Integration

The 190501-07-00-01 is designed to integrate seamlessly with Bently Nevada monitoring systems. Its standard MIL-C-5015 connector ensures compatibility with existing cabling infrastructure. The transducer's output can be connected to vibration monitors, data collectors, or distributed control systems (DCS) for continuous monitoring. For specific integration details, refer to the official Bently Nevada documentation or contact Petro Auto Tech for technical support.
