Product Details
Signal Characteristics and Measurement Range
1. Sensitivity: 100 pC/g ±5%
CA202 144-202-000-126 Piezoelectric Accelerometer provides a sensitivity of 100 pC/g ±5%, which defines the electrical charge generated per unit of acceleration. This parameter is essential for determining signal scaling in vibration measurement systems, especially when used with charge amplifiers or data acquisition modules. The defined tolerance supports consistent signal interpretation across identical measurement setups.
3. Measurement Range: 0.01 – 400 g Peak
With a measurement range of 0.01 to 400 g peak, the device is capable of detecting both subtle vibration changes and high-intensity acceleration events. This range provides flexibility in monitoring different machine conditions, from early-stage vibration anomalies to heavy mechanical impact levels observed in industrial equipment.
2. Frequency Range: 0.5 – 6000 Hz
The sensor supports a wide frequency response from 0.5 Hz to 6000 Hz, allowing it to capture both low-frequency structural vibrations and higher-frequency mechanical signals generated by rotating equipment. This range enables use in applications such as machinery condition monitoring, where different fault signatures may appear across varying frequency bands.
4. Combined Signal Output Behavior
The combination of charge output signal type with defined sensitivity and measurement range allows the sensor to interface with standard vibration analysis systems. Signal output is typically processed through external charge conditioning equipment, ensuring compatibility with industrial monitoring and diagnostic platforms used in vibration analysis applications.
Key Advantages

Common Purchasing FAQs
1. What type of output signal does this sensor provide?
The CA202 features a"charge output"; it outputs a charge signal proportional to acceleration and requires an external charge amplifier or signal conditioning module.
2. Can it be connected directly to a PLC or data acquisition system?
No, direct connection is not possible. Since the output is a charge signal, it must be converted into a voltage signal via a charge amplifier before connecting to a PLC, DAQ, or vibration analysis system.
3. What does "100 pC/g ±5%" mean?
It indicates a sensor sensitivity of 100 picocoulombs (pC) of charge output per 1g of acceleration, with a tolerance of ±5%. This parameter is used for vibration signal conversion and calibration.
4. Does the 0.5 Hz low-frequency response mean it can measure structural vibration?
Yes. The 0.5 Hz starting frequency allows it to be used for low-frequency structural vibration analysis, such as on large equipment foundations, bridge structures, and low-speed rotating machinery.
