The part number 26530-05 is a specific configuration of a Dual Probe Transducer System manufactured by Bently Nevada. This system is a critical component in machinery protection and condition monitoring systems for rotating equipment.

Product Description

The Bently Nevada 26530 Dual Probe Transducer System is designed to provide comprehensive vibration and position measurements for critical rotating machinery. The "dual probe" aspect indicates that it consists of a proximity probe (which measures relative shaft displacement) and a seismic transducer (such as an accelerometer or Velomitor, which measures absolute casing vibration) installed together in a single, common housing. This unique design allows for simultaneous measurement of both relative and absolute motion at approximately the same point on the machine.

The system is particularly valuable for gaining a more complete understanding of machine behavior, as it can combine the data to determine parameters like shaft absolute position and vibration (often referred to as "Shaft Absolute") and shaft centerline position information. This combination of measurements is crucial for advanced diagnostics like orbit analysis. The "-05" in the part number signifies a specific configuration within the 26530 series, often related to probe lead length, fitting options, or other physical characteristics.

Product Application Cases

The Bently Nevada 26530-05 Dual Probe Transducer System is applied in industries with critical rotating machinery where comprehensive and continuous health monitoring is essential for safety, reliability, and operational efficiency.

• Power Generation: Used extensively on large steam turbines, gas turbines, and generators to monitor shaft vibration and position, ensuring stable operation and preventing costly damage from issues like unbalance, misalignment, and bearing wear.
• Oil and Gas Industry: Critical for safeguarding large compressors (centrifugal and reciprocating), pumps, and expanders in refineries, pipelines, and offshore platforms. It helps detect internal rubs, shaft cracks, and other subtle faults that could lead to catastrophic failure.
• Petrochemical and Chemical Processing: Applied to protect key rotating equipment like reactor agitators, large fans, and critical pumps, where precise monitoring helps maintain continuous production and prevent hazardous events.
• Pulp and Paper Industry: Used on dryer sections, refiners, and large fans to monitor vibration and ensure smooth, continuous operation, which is vital for product quality and throughput.
• Other Heavy Industries: Deployed in sectors such as mining, metals, and cement on large motors, mills, and crushers to gain deep insights into machine health and enable predictive maintenance strategies.
