Description

Designed for early-stage rolling element bearing and gearbox defect detection, the Bently Nevada 200157-18-CN serves as a specialized high-frequency accelerometer within the Trendmaster Pro monitoring ecosystem. This enveloping accelerometer is engineered to capture high-frequency stress waves generated by impact-type faults, allowing machinery diagnostic systems to identify structural degradation long before it manifests as low-frequency velocity or displacement vibration.

The 200157-18-CN features a hermetically sealed 316L stainless steel housing, making it highly resilient against corrosive industrial environments, chemical washdowns, and high relative humidity. This specific model configuration utilizes the "18" mounting stud option, providing a 3/8-24 to M8x1 1-3/8 inch hex plate stud for rigid, mechanically sound installation on machine casings. The "CN" designation specifies regional/country-specific approvals, ensuring regulatory compliance within designated deployment territories.

Features

  • Optimized for high-frequency vibration enveloping to detect rolling element bearing faults and gear mesh anomalies.
  • Constructed with a rugged 316L stainless steel housing for superior chemical and environmental resistance.
  • Features a top-exit 5-pin 1/2-20 electrical connector for secure, reliable signal transmission.
  • Hermetically sealed design capable of withstanding 100% condensing, non-submerged relative humidity.
  • Includes a factory-configured 3/8-24 to M8x1 hex plate stud for precise torque transmission and sensor coupling.

Applications

  • Electric motors and industrial pumps.
  • Cooling tower fans and blowers.
  • Gearboxes and transmission units in pulp and paper mills.
  • High-speed manufacturing and assembly rotating equipment.
  • Petrochemical and power generation auxiliary machinery.

Installation Guidelines

To ensure accurate signal transmission and prevent mechanical resonance errors, the 200157-18-CN must be mounted flush against a clean, flat, and perpendicular surface. The recommended mounting torque of 2.7 to 6.8 N*m (2 to 5 ft*lbf) must be strictly adhered to; under-torquing can lead to poor high-frequency response, while over-torquing can damage the internal sensor crystal or the mounting thread.

Applying a thin layer of silicone grease or acoustic coupling fluid between the sensor base and the machine casing is highly recommended to improve transmissibility. Avoid routing the sensor cabling parallel to high-voltage AC power lines to mitigate electromagnetic interference.

FAQ

What is the purpose of the 'CN' suffix in the 200157-18-CN model number?

The 'CN' suffix designates regional and country-specific approvals and certifications, verifying that the unit complies with local industrial safety and import regulations.

What mounting stud size does the '18' option represent?

The '18' mounting option specifies a 3/8-24 to M8x1 thread adaptor integrated with a 1-3/8 inch hex plate stud, allowing secure mechanical installation on standard M8 threaded machinery casings.

What is the sensitivity rating of the Bently Nevada 200157-18-CN?

The accelerometer features a sensitivity of 10.2 mV/(m/s2) (which corresponds to 100 mV/g) measured at a reference frequency of 80 Hz with a tolerance of plus or minus 12%.

Can this sensor be fully submerged in liquid?

No. While the sensor is hermetically sealed to withstand 100% condensing relative humidity, it is rated for non-submerged operation only.
