The CA901 144-901-000-701 is an explosion-proof piezoelectric accelerometer from Meggitt Vibro-Meter’s CA901 series, designed specifically for long-term vibration monitoring, development testing, loose component monitoring, and high-temperature applications. The CA901 utilizes a VC2 single-crystal sensing element configured for compression mode and is equipped with an electrically isolated sensing system, a mineral-insulated cable, and a fully hermetically sealed Inconel 600 housing, providing stable charge output measurements.
Main Functions & Features
1. Loose Component Monitoring
The CA901 accelerometer measures mechanical acceleration and generates a charge signal for processing by external monitoring equipment, making it suitable as a sensing element in systems that monitor vibration and shock-related mechanical events.
2. ATEX Certification
The CA901 144-901-000-701 is listed in Meggitt’s EU Declaration of Conformity and complies with ATEX intrinsic safety (Ex ia) and non-sparking (Ex nA) protection requirements.
3. Stable Piezoelectric Acceleration Measurement
The CA901 accelerometer utilizes VC2 single-crystal material and has a random dynamic measurement range of 0.001 g to 200 g peak. For spike signals, its overload capacity reaches 500 g peak, ensuring stable measurement performance.

2. How does the CA901 work?
— The CA901 utilizes a VC2 single-crystal piezoelectric sensing element and a compression-mode structure. When acceleration acts on the sensor, the piezoelectric element generates a charge corresponding to the applied mechanical acceleration; the charge signal is transmitted via a two-conductor mineral-insulated cable to a compatible charge converter for processing.
3. In which fields is the CA901 primarily used?
— The CA901 is specifically designed for long-term, high-temperature monitoring. It is suitable for applications requiring stable acceleration measurements under extreme high temperatures and over extended periods, such as monitoring loose components. The CA901 can also be used for development and engineering testing, as well as monitoring in potentially explosive atmospheres.
