The S3960 AC46286 144-201-000-222 is a high-temperature, industrial-grade, charge-output piezoelectric accelerometer for heavy turbomachinery. Thanks to its laser-welded stainless steel housing and hermetically sealed armored cable, it operates stably over the long term in extreme, high-heat environments from −54°C to +260°C, providing a nominal sensitivity of 100 pC/g.
Industrial vibration monitoring
Hermetically welded
Differential output
The vibro meter CA 201 piezoelectric accelerometer 144-201-000-222 is equipped with a symmetrical shear mode polycrystalline measuring element, featuring internal case insulation. The transducer is engineered for heavy-duty industrial monitoring and precision measurement of machinery vibration. It is fitted with an integral signal cable protected by a stainless steel flexible tube that is hermetically welded to the sensor casing. The CA 201 accelerometer is available in CENELEC-approved hazardous area versions and delivers high sensitivity for critical diagnostic applications. In terms of environmental defense, this specific model features an industry-leading integral signal cable.
The outer flexible stainless steel armored tube is hermetically welded to the sensor body using continuous laser welding technology, delivering a true IP68 rating capable of enduring prolonged immersion in high-temperature industrial lube oil, chemical splashes, and high-pressure steam without any ingress. Operating on a pure charge-output mechanism without internal semiconductor electronics, the transducer boasts exceptional ultra-high temperature resilience, making it the preferred choice for gas turbine enclosures, steam turbines, and heavy-duty extruder bearings.
Furthermore, the product fully complies with stringent CENELEC intrinsic safety standards for hazardous area deployment, offering seamless compatibility with VM600 machinery protection systems or external signal conditioners to provide robust, fail-safe machinery monitoring and automatic trip protection.

Thermal Power Plants
Used for ultra-supercritical main steam turbine high-pressure cylinder monitoring. It monitors the absolute casing vibration of high-pressure and IP cylinder bearing pedestals on main steam turbines, where its pure charge-output mechanism prevents failure in high-temperature environments caused by steam leakage.
Petrochemical
Used for high-temperature hydrocracking compressor monitoring. Leveraging its strict hazardous area certifications, it is mounted on reciprocating or centrifugal compressors within hydroprocessing units involving high safety risks and elevated temperatures to capture valve degradation and bearing wear.
Nuclear Power
Used for nuclear island main pump and reactor coolant pump casing monitoring. In the highly radioactive, high-temperature, and high-pressure environment inside the nuclear island, it continuously monitors the structural vibration of primary reactor coolant pumps to ensure primary loop safety.
Steel & Metallurgy
Used for blast furnace blowers and hot rolling mill main gearbox monitoring. It is deployed on massive axial blowers for ironmaking blast furnaces and main drive gearboxes on red-hot steel ingot rolling lines subjected to severe impact loads, resisting strong vibrations and thermal radiation.
Coking & Coal Chemical
Used for coke oven raw gas blower condition monitoring. It monitors the bearing pedestal vibration of exhaust fans drawing out high-temperature coke oven gas, with the integral steel armored cable protecting against corrosive tar stains and hot gas erosion.
When operating the Vibro-Meter CA201 (144-201-000-222), it is strictly forbidden to connect it directly to standard voltage or current acquisition boards; it must be paired with charge amplifiers like IPC704/IPC707 to convert the weak charge signals. For field installation, it must be cross-tightened uniformly using 4 M6 screws at a standard torque of 15 Nm, ensuring the mounting surface is perfectly flat and clean to prevent high-frequency signal distortion.
Although the sensor head and cable can withstand high temperatures up to +260°C, the armored stainless steel hose must be protected from excessive bending or heavy crushing during routing to strictly prevent signal leakage or short circuits caused by mechanical damage to the internal specialized shielded wires.
Vibro-Meter CA201 144-201-000-222 is an intrinsically safe, high-temperature charge-output industrial accelerometer for turbomachinery. Its laser-welded stainless steel housing and armored cable withstand extreme temperatures from −54°C to +260°C. Providing a 100 pC/g sensitivity, it eliminates ground loops via case isolation. Paired with IPC704/IPC707 charge amplifiers, it is essential for predictive maintenance of gas/steam turbines and large compressors.
What is the Vibro-Meter S3960 AC46286 144-201-000-222?
It is a high-sensitivity, industrial-grade, shear-mode piezoelectric accelerometer manufactured by Vibro-Meter (a Meggitt brand), designed for vibration monitoring of heavy rotating machinery.
How does the S3960 AC46286 144-201-000-222 device work (piezoelectric principle)?
When the machinery vibrates, its internal polycrystalline piezoelectric element generates microscopic dynamic charge signals under shear force, which are strictly proportional to the vibration acceleration.
