The 200150-22-CN is a case-mounted piezoelectric accelerometer manufactured by Bently Nevada for Trendmaster monitoring systems. Designed for mass-deployed rolling element bearing machinery such as motors and pumps, it features a hermetically sealed stainless steel casing with an internal piezoelectric element to convert vibration into a differential voltage signal proportional to acceleration. The suffix -CN signifies that it is certified with China local explosion-proof approvals (CCC Ex / NEPSI), ensuring compliance with hazardous area regulations in the China market.
Hermetically Sealed Stainless Steel Casing
Trendmaster Ecosystem Integration
Piezoelectric Sensing Engine
The 20015x Accelerometers are general purpose, wide frequency, case-mounted seismic transducers designed for use with Trendmaster ProTIMs. The 200150 Accelerometer also operates with the Trendmaster 2000 system. The accelerometer interfaces with the 200100 Dual Acceleration to Velocity flexiTIM Module and the 89130-01 Acceleration-to-Velocity TIM (Transducer Interface Module), as well as the 1900/25 and 1900/27 monitors.
The 20015x Accelerometers feature a hermetically sealed, stainless steel case. This design provides an extremely rugged transducer that is well suited for harsh industrial environments. The transducer’s top-mounted, 5-pin connector allows you to easily install and remove the interconnecting signal cable. A 3/8-24 threaded hole on the bottom of the sensor’s casing accommodates several mounting options. The 20015x Accelerometers contain a piezoelectric sensing device that generates a charge when it is subjected to vibration.
The accelerometers electronically convert this charge to a differential voltage signal that is proportional to the acceleration that is parallel to the sensitive axis of the transducer.

Oil & Gas
Used for water injection pump and auxiliary fan monitoring. It is installed on auxiliary pumps and cooling tower fans in refineries and drilling platforms, enabling low-cost centralized vibration monitoring for hundreds of points via the Trendmaster bus system.
Petrochemical
Used for reactor agitator bearing monitoring. Utilizing its -CN hazardous area certification, it is mounted on reactor bearing housings within hazardous zones to detect early fatigue spalling and pitting of rolling element bearings.
Thermal Power Generation
Used for coal pulverizer and induced draft fan monitoring. In harsh, high-temperature, and dusty environments, it monitors the casing acceleration of coal pulverizer gearboxes and boiler fans to prevent broken teeth and bearing burnout.
Hydropower
Used for plant drainage pumps and motorized valve actuators. It is used on peripheral drainage pumps and high-pressure valve linkage mechanisms to assess valve operation and pump cavitation through high-frequency vibration analysis.
Wind Power
Used for wind turbine yaw motors and yaw gearboxes. It is installed on yaw system motors and planetary gearboxes inside the wind turbine nacelle to detect mechanical anomalies and structural looseness during yaw operations.
When using the 200150-22-CN sensor, it must be vertically tightened onto a rigid surface with the specified torque using silicone grease to ensure high-frequency transmission, the top 5-pin connector must be locked with proper oil/waterproofing, hazardous area deployment must strictly follow its -CN intrinsic safety certification by wiring to designated modules, and signal cables must be physically secured away from strong EMI sources like VFDs.
Bently Nevada 200150-22-CN is a general-purpose, wide-frequency, case-mounted industrial seismic accelerometer designed for use with Trendmaster Pro/2000 systems and 1900 series monitors. Featuring a hermetically sealed 316L stainless steel case, it is dustproof, waterproof, corrosion-resistant, and capable of long-term stable operation in harsh industrial environments ranging from -40°C to +105°C. At its core, the sensor integrates an advanced shear piezoelectric sensing element to accurately convert mechanical vibration into low-noise differential voltage signals. The specific "-22" suffix indicates that it comes with a 3/8-24 to M8 hex plate mounting stud for seamless installation onto various metric machinery, while the "-CN" suffix represents local Chinese explosion-proof and intrinsic safety certifications, making it fully compliant for machinery condition monitoring and protection in high-risk domestic sectors such as petrochemicals, metallurgy, and power generation.
The 200150-22-CN is an eddy current Proximitor Sensor manufactured by Bently Nevada (typically for 11mm or 16mm measurement systems), used for long-range displacement and vibration monitoring on large rotating machinery.
How do you use the 200150-22-CN?
It is installed in a protective enclosure, connected to an eddy current probe via an extension cable, and outputs an analog voltage signal to a Bently Nevada 3500 monitoring system or DCS.
What are the main industries that use the 200150-22-CN?
It is widely used in power generation (steam turbine-generators), oil & gas (large compressors), chemical, and metallurgical industries for critical rotating asset protection.
What is the working principle of the 200150-22-CN?
It utilizes the eddy current principle: driving the probe with high frequency to generate an electromagnetic field. As the metal shaft approaches, eddy current losses occur, which the Proximitor converts into a proportional voltage signal.
What is the standard scale factor of the 200150-22-CN?
As a large-diameter system component, its standard scale factor is typically 3.94 V/mm (100 mV/mil), with a linear range usually twice that of an 8mm probe.
