Bently Nevada 200150-18-05 General Purpose Accelerometer with Multiple Approvals

Product Introduction

When unplanned vibration spikes threaten rotating machinery uptime, the Bently Nevada 200150-18-05 provides reliable, continuous acceleration monitoring. This general-purpose accelerometer is designed for use with Trendmaster 2000 or Trendmaster Pro systems, delivering accurate data for predictive maintenance programs. Manufactured in the U.S.A., this sensor combines proven piezoelectric sensing technology with robust 316L stainless steel construction to withstand harsh industrial environments.

Technical Specifications Breakdown

The 200150-18-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring consistent signal output for precise vibration analysis. Its measurement range spans ±245 m/s² (±25 g), covering most machinery monitoring needs without saturation. The frequency range of 10 to 1000 Hz (600 to 60,000 cpm) captures both low-speed and high-speed rotating equipment vibrations. With a mounted resonant frequency exceeding 20 kHz (>1200 kcpm), the sensor avoids resonance interference in typical industrial applications. Amplitude linearity of ±2% (1 to 10 g pk) guarantees accurate readings across the operating range, reducing false alarms and maintenance costs.

Industry Applications

This accelerometer excels in monitoring pumps, fans, compressors, and motors in industries such as oil and gas, power generation, and manufacturing. For example, in a refinery cooling tower fan, the 200150-18-05 detects early bearing degradation, allowing planned repairs during scheduled outages rather than costly emergency shutdowns. Its 100% condensing humidity rating and hermetic sealing (5X10⁻⁸ atm•cc/s max) make it suitable for outdoor or washdown environments where moisture ingress would damage lesser sensors. The multiple approvals (CSA, ATEX, IECEx) simplify global deployment, eliminating the need for different sensor variants per region.

Installation & Setup Guidance

Mount the 200150-18-05 using the 3/8-24 female thread with a torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) for optimal coupling. The mounting stud option 18 includes a 3/8-24 to M8x1 1-3/8 inch hex plate stud, facilitating installation on metric or imperial mounting points. Ensure the mounting surface is clean, flat, and free of paint or debris to maximize frequency response. The sensor settles within 300 ms of power application, allowing rapid commissioning. Excitation voltage of 4.7 to 5.5 Vdc from the Trendmaster module powers the internal electronics, with quiescent current below 800 µA for low system power draw.

Maintenance & Reliability

Routine inspection of the cable and connector integrity every six months helps prevent signal degradation. The 316L stainless steel housing resists corrosion, while the hermetic seal maintains internal integrity even in condensing humidity. Operating temperature range of -40 °C to +105 °C (-40 °F to +221 °F) covers most industrial environments, reducing the need for thermal protection enclosures. The ceramic shear sensing element offers long-term stability, minimizing drift-related recalibration costs over the sensor's service life.

Selection Guide & Purchasing Advice

Before ordering the 200150-18-05, verify that your Trendmaster 2000 or Trendmaster Pro system supports the -01 standard acceleration-to-velocity channel type. Confirm the mounting thread compatibility with your machine's stud pattern. For complete technical specifications, please contact BluePLC Industrial.
