Product Describe：
CA202 piezoelectric accelerometer
Frequency response: 0.5 to 6 000 Hz
Temperature range: −55 to 260 °C
2-pin system, insulated from case, charge output
The CA202 144-202-000-215 is a piezoelectric accelerometer from Meggitt’s vibro-meter product line. The CA202 sensor features a symmetrical shear-mode polycrystalline measuring element with internal case insulation in an austenitic stainless-steel case (housing).
Symmetrical sensor with internal case insulation and differential output
Hermetically welded austenitic stainless-steel case and heat-resistant stainless-steel protection hose
Available in standard versions and Ex versions certified for use in potentially explosive atmospheres
Equipped with an integral low-noise cable, the CA202 features a flexible, hermetically welded, leak-tight stainless-steel protection hose. It is available in Ex (hazardous areas) and standard versions for demanding industrial vibration monitoring and measurement applications. The Meggitt Vibro-Meter CA202 144-202-000-215 piezoelectric accelerometer is primarily applied in long-term dynamic vibration monitoring of heavy-duty industrial rotating machinery.
This sensor features internal symmetrical shear-mode piezoelectric polycrystalline measuring elements and an insulated housing structure, which effectively suppresses common-mode interference. Constructed from austenitic stainless steel, the housing is integrated with a heat-resistant stainless steel flexible protective conduit through a hermetic, watertight welding process, providing excellent sealing ratings and chemical resistance.
This specific model is a standard non-explosion-proof version that comes with a built-in 6-meter low-noise integral cable. It operates across a wide temperature range from -55°C to +260°C and delivers a dynamic measurement range up to 400 g. The sensor output is a high-charge signal, in practical industrial measurement loops, it must be paired with an external charge amplifier (such as the IPC704 signal conditioner) to convert the charge signal into standard current or voltage signals for integration into machinery protection systems like the VM600.

Gas Turbine Power Plants
Measures high-frequency casing vibration and combustor instability on heavy-duty gas turbines under extreme high-temperature environments.
Steam Turbine Generation
Monitors high-pressure casing vibration and steam-excited rotor instabilities near fluid-film bearings in thermal power plants.
Petrochemical Refining
Monitors continuous vibration on high-speed centrifugal compressors and hazardous gas process pumps inside explosive atmospheres.
Oil and Gas Pipelines
Provides real-time acceleration data and bearing health indicators for large gas turbine drives located at cross-country booster stations.
Nuclear Power
Monitors structural vibration and cooling pump casing balance in containment buildings, utilizing the sensor's high-temperature and leak-tight construction.
Hydropower Stations
Tracks structural and bearing vibrations on high-head Pelton or Francis turbines exposed to severe water-wash and humid conditions.
Pair the sensor with a dedicated charge amplifier and never cut the integral cable to prevent signal distortion. Maintain a bend radius above 50 mm during protection hose routing. Ensure a flat mounting surface and tighten strictly to 6.5 N·m to avoid high-frequency degradation or element damage. Maintain electrical isolation between the sensor/hose and the machinery ground to eliminate ground loop interference.
Vibro-Meter CA202 144-202-000-215 is a highly reliable industrial piezoelectric accelerometer primarily used for long-term dynamic vibration monitoring of heavy-duty rotating machinery, such as steam and gas turbines. This model is a standard non-explosion-proof version featuring an austenitic stainless steel housing, which is hermetically welded to integrate a 6.0-meter low-noise cable protected by a flexible stainless steel conduit. Utilizing internal symmetrical shear-mode measuring elements and a case-isolated structure, it delivers excellent electromagnetic interference resistance, high-temperature endurance , and a 400 g dynamic range. Since it outputs a high-impedance charge signal, it must be paired with an IPC704 signal conditioner in practical industrial loops to convert the output into standard signals for integration into machinery protection systems like the VM600.
It is an industrial piezoelectric accelerometer primarily used for long-term, dynamic vibration monitoring of heavy-duty rotating machinery like gas and steam turbines.
How do you properly use products like the CA202 144-202-000-215?
It must be rigidly mounted onto the machine bearing housing, connected via its 6-meter integrated cable to a charge amplifier, and then routed to a machinery protection system like the VM600.
What type of signal does the CA202 144-202-000-215 output?
It outputs a high-impedance charge signal (measured in pC/g). It cannot be directly connected to standard data acquisition cards and must be modulated by a charge amplifier first.
Can the CA202 144-202-000-215 be used in explosive hazardous areas?
No. The model with the -215 suffix is a standard non-explosion-proof version. If hazardous area certifications (such as Ex ia or Ex nA) are required, other specific suffixed models within the series must be selected.
Why can the CA202 144-202-000-215 effectively suppress common-mode interference on industrial sites?
Because it utilizes internal symmetrical shear-mode piezoelectric polycrystalline measuring elements and features an insulated housing design that eliminates ground loop noise.
