The Vibro-Meter CA901 provides reliable data under the most intense industrial conditions. This specific model (144-901-000-222) includes an integrated 12.5-meter cable (designated by the "22" suffix) and a Lemo connector. The sensor produces a charge output with a nominal sensitivity of 10 pC/g. It complies with major nuclear and industrial standards, including NRC guide 1.133 and IEEE 323-1974. Furthermore, the unit features integral case insulation to prevent ground loops. Therefore, the Vibro-Meter CA901 remains the industry standard for high-integrity monitoring in extreme thermal environments.
This accelerometer thrives where standard sensors fail. It operates continuously between -54°C and +650°C, withstanding extreme peaks from -196°C to +700°C. The housing utilizes Inconel 600 and features hermetic welding for maximum durability. Additionally, the CA901 withstands high radiation doses. It handles gamma flux up to $10^{11}$ erg/g and neutron flux up to $10^{18}$ $n/cm^2$ without performance degradation. Consequently, the sensor provides stable monitoring within nuclear containment areas and high-pressure steam environments.
The Vibro-Meter CA901 maintains high accuracy across a broad frequency spectrum. It delivers a flat response (±5%) from 3 Hz to 2800 Hz. The sensor detects vibration levels from 0.001 g up to 200 g peak, with an overload capacity of 500 g for transient spikes. To ensure signal purity, the internal insulation resistance exceeds $10^9$ Ω. Furthermore, the unit holds ATEX certification for use in explosive atmospheres (Zones 0, 1, and 2). Therefore, the hardware delivers clean, reliable position and vibration data in hazardous or high-interference locations.
The Vibro-Meter CA901 is a passive piezoelectric device. It requires no external input power and generates a charge signal proportional to the sensed acceleration. You should process this signal using a dedicated charge converter or signal conditioner. The sensor head features a high resonance frequency of over 17 kHz, which prevents mechanical interference within the operating range. These specifications make the CA901 an essential tool for detecting structural defects or loose components in high-speed rotating machinery.
You should mount the Vibro-Meter CA901 inside a tube or directly to the machine surface using 4 Allen M6 screws. Apply a fastening torque of 15 Nm to ensure a rigid mechanical path. This specific version features a 12.5-meter integral cable, providing ample reach for remote junction boxes. The total weight of approximately 1.15 kg includes the extended cable assembly. Finally, the Lemo connector offers a secure, vibration-resistant interface for connection to your monitoring system.
First, inspect the mounting location. Ensure the surface is flat to allow for the 17 kHz resonance frequency performance. Secure the Vibro-Meter CA901 using the 4 Allen M6 screws and tighten them to 15 Nm. Next, route the 12.5-meter cable carefully. Avoid areas with high electromagnetic noise. Connect the Lemo connector to your charge converter. Furthermore, ensure the cable is secured with clamps to prevent fatigue from high-vibration exposure. Finally, check the output on your diagnostic terminal to verify the sensitivity aligns with the factory 10 pC/g specification.

Q: What is the primary application for the CA901?
The Vibro-Meter CA901 is specifically designed for loose part monitoring and high-temperature vibration sensing in power plants and aerospace test cells.
Q: Does the 12.5m cable affect the sensitivity?
The sensitivity remains 10 pC/g. However, the long cable increases the total capacitance (200 pF/m). You must calibrate your charge converter to account for this total capacitance.
Q: Can this sensor handle liquid nitrogen temperatures?
Yes. With a lower limit of -196°C, the CA901 is fully operational in cryogenic applications.
Q: Is the sensor head protected against moisture?
Yes. The Inconel 600 housing is hermetically welded, providing a gas-tight and moisture-proof seal for high-pressure environments.
Q: What is the benefit of the Lemo connector?
The Lemo connector provides a quick-connect, self-latching interface that is highly resistant to industrial vibration and unintentional disconnection.
