The sensor also supports the 164746-01 Seismic Direct Input Card. These combinations provide a complete path for predictive maintenance data. The transducer performs optimally when calibrated at 100 Hz within standard thermal ranges.

Industrial Applications

Reliability makes this sensor ideal for continuous vibration tracking on rotating equipment. It monitors motors, pumps, and small fans in power plants and refineries. The rugged build quality supports use in cooling tower environments. Maintenance teams use the resulting data to identify bearing wear and imbalance early. Consequently, this leads to reduced repair costs and less unplanned downtime.

Key Technical Characteristics

  • Hermetic sealing protects internal electronics from humid or dusty industrial air.
  • Stainless steel construction provides superior durability against mechanical impacts.
  • The 1/4-28 threaded hole accommodates various mounting studs and adapters.

Technical Overview

The Bently Nevada 200350-12-00-00 is a general-purpose, case-mounted industrial accelerometer designed for measuring absolute bearing housing or machine casing vibration. It utilizes a piezoelectric sensing element that generates a low-impedance voltage signal directly proportional to the acceleration of the component to which it is mounted. This analog voltage signal is transmitted via a two-wire system, which also supplies constant current power to the sensor's internal electronics (IEPE standard). The 200350-12-00-00 is specifically engineered for integration with Bently Nevada machinery protection systems, such as the 3500 series. It directly interfaces with the 3500/42M Proximitor/Seismic Monitor, which processes the raw acceleration signal. The monitor can then provide real-time acceleration data or perform single integration to derive velocity, a common parameter for assessing rotating machinery health. Constructed from 316L stainless steel with a hermetic seal, the 200350-12-00-00 is built to withstand harsh industrial environments, ensuring reliable signal transmission and long operational life in critical machinery monitoring applications.

Operational Capabilities

In Oil & Gas and Power Generation applications, the 200350-12-00-00 provides essential data for condition monitoring of critical assets like gas and steam turbines, compressors, pumps, and generators. Its reliability is substantiated by its robust construction; the hermetically sealed 316L stainless steel housing (rated to IP68) prevents ingress of moisture, chemicals, and particulates common in these environments. The sensor is designed for high MTBF (Mean Time Between Failures) through the use of solid-state electronics and minimal moving parts. Environmentally, the 200350-12-00-00 is specified to operate reliably from -55 °C to +121 °C, accommodating a wide range of ambient and machine surface temperatures. It is also designed to survive high-g shock events (up to 5000 g peak), ensuring data integrity is maintained even during machinery startup, shutdown, or upset conditions.

Applications

  • Power generation turbines and generators
  • Oil & gas compressors and pumps
  • Industrial rotating machinery monitoring
  • Predictive maintenance systems

Technical FAQ

Q: What systems is the 200350-12-00-00 compatible with?
A: The 200350-12-00-00 is designed for primary compatibility with Bently Nevada monitoring systems, including the 3500 Machinery Protection System (interfacing with the 3500/42M Proximitor/Seismic Monitor) and the 3300 Monitoring System. It is also compatible with any third-party data acquisition or monitoring system that can provide standard IEPE (Integrated Electronics Piezo-Electric) sensor power, specifically a constant current source of 2 to 10 mA at a voltage of 18 to 30 VDC.

Q: What are the installation requirements?
A: Proper installation is critical for accurate measurement. The mounting surface must be a flat, smooth (recommended finish of 0.8 μm / 32 μin Ra), and clean area on the machine case. A single mounting hole must be drilled and tapped for the sensor's 1/4-28 UNF mounting stud. Apply a thin, uniform layer of coupling fluid (silicone grease) to the mounting surface to eliminate air gaps and ensure optimal vibration transmission. The sensor must be tightened to the specified torque of 2.7 to 5.4 N·m (24 to 48 lbf·in) using a calibrated torque wrench. Ensure the interconnecting cable is routed to prevent strain on the connector and is shielded from high-voltage lines or other sources of electromagnetic interference. Use of conduit is recommended for physical protection.
