Product Introduction
144-901-000-282 is a piezoelectric acceleration sensor, which is used to measure mechanical vibrations in industrial applications such as vibration monitoring, mechanical health diagnosis, and protection of rotating equipment. The piezoelectric acceleration sensor utilizes the piezoelectric effect to convert mechanical vibration (acceleration) into an electrical charge signal for output. This signal is then converted into voltage or current by an external signal conditioner, which is provided for the control system or monitoring instrument to collect and analyze.CA901 144-901-000-282 Cangers with a piezoelectric acceleration meter is a vibration sensor, which can provide a charge output. Therefore, an external charge amplifier (such as an IPC707 signal regulator) is needed to convert the charge signal to a current or voltage signal.

Product Details
The use of VC2-type single-crystal material in the 144-901-000-282 CA 901 compression mode accelerometer provides an extremely stable instrument. The transducer is designed for long-term monitoring or development testing. It is fitted with an integral mineral-insulated cable (twin conductors), which is terminated with a Lemo or a high-temperature connector.
144-901-000-282 CA901 is designed and manufactured for long-term use in harsh environments such as high temperature and/or dangerous areas (potential explosive gas environments). It can work at extreme temperatures, higher than the melting temperature of aluminum (660 °C).
Provide the most trusted solutions for the world's most challenging survey applications.
Most transport aircraft rely on the acceleration meter of MEGGITT to monitor the status and health of the engine.
Make engine manufacturers fine-tune the engine to improve efficiency and enable operators to optimize their maintenance work.

Installation method
Threaded fixation: Secure the threaded bottom of the sensor to the main body of the device to ensure a good mechanical coupling.
Surface treatment of measurement interface: Before installation, use a scraper or a flat grinding tool to ensure the installation surface is smooth, thereby reducing mechanical coupling errors.
Installation torque: Tighten according to the recommended torque value provided by the manufacturer (e.g., 15 N·m). Avoid being too loose or too tight, as this may cause distortion or damage.
When purchasing the Meggitt 144-901-000-282 Piezoelectric Accelerometer sensor, the following factors should be taken into consideration:
The frequency range of the measurement target: Ensure that the frequency response of the sensor covers the vibration characteristics of the target.
Installation environment temperature: Determine whether a high-temperature version is required or if additional mineral-insulated cables need to be provided.
Signal conditioning accessories: Purchase a suitable charge amplifier or signal conditioning device (such as IPC707).
Explosion-proof certification requirements: Select the version with the corresponding certification for environments that are flammable and explosive.
Accuracy and linearity requirements: For higher sensitivity accuracy, consider specific versions or calibration services.
