The CA306 144-306-000-321 is a piezoelectric accelerometer for extreme environments like aerospace and industrial gas turbines. It requires an external charge converter, such as the Meggitt IPC707 Signal Conditioner.
Designed for high temperature gas turbine applications
Improved transverse frequency resonance
4-hole mounting according to ARINC Characteristic 554
The CA 306 series of high temperature accelerometers has been designed specifically for gas turbine applications. The accelerometers feature a rugged design with hermetically sealed connectors. An integral mineral insulated (MI) cable with stainless steel overbraid ensures signal integrity even in the most hostile environments. The differential output signal minimizes noise pick-up due to electrical ground potentials. A version with side connector is available when an integral cable is not required.
The CA306 144-306-000-321 operates across a thermal range from -55°C to +500°C without thermal degradation or calibration drift. The hermetically welded Inconel alloy housing protects internal elements against oxidation, mechanical fatigue, and corrosive gas turbine exhaust.As a high-impedance, charge-mode sensor, it outputs a raw signal directly proportional to dynamic acceleration.
Interfacing the unit with an external charge converter, such as the Meggitt IPC707 Signal Conditioner, provides high electromagnetic immunity and maximum signal-to-noise ratios. This configuration enables continuous monitoring on thermally stressed turbine components—including bearing casings and combustor accessories—to prevent catastrophic equipment failure and unplanned downtime.

When utilizing the Vibro-Meter CA306 144-306-000-321, operators must strictly adhere to the +500°C upper thermal limit and observe the minimum bending radius of the integral mineral-insulated cable, avoiding sharp kinks on the hard-line armoring.
Due to the high-impedance nature of the charge output, the connection interfaces must remain perfectly dry and clean to prevent signal leakage or impedance drops caused by moisture and dust. Furthermore, field deployment requires twinaxial shielded differential routing to a nearby compatible charge conditioner, such as the IPC707, to isolate ground loop potentials and guarantee dynamic signal integrity.
Characterized by an expansive operating thermal envelope from -55°C to +500°C, the Vibro-Meter CA306 144-306-000-321 piezoelectric accelerometer maintains long-term performance stability free from heat-induced degradation. The assembly incorporates an integrated mineral-insulated (MI) cable, which yields robust mechanical reinforcement and electrical shielding to counter severe ambient conditions while preserving original signal quality.
What is the Vibro-Meter CA306 144-306-000-321 piezoelectric accelerometer?
It is an industrial-grade charge-output accelerometer utilizing a hermetically sealed Inconel alloy housing and a highly reliable piezoelectric crystal element, specifically serving vibration monitoring in extreme environments like aerospace and industrial gas turbines.
How does the Vibro-Meter CA306 144-306-000-321 ensure stable operation without thermal decay under high temperatures?
Relying on its high-performance piezoelectric crystal element and strict hermetic sealing, it eliminates thermal degradation and maintains long-term calibration accuracy even under severe conditions up to +500°C.
What should be noticed during the routing and deployment of the Vibro-Meter CA306 144-306-000-321 cable?
Operators must strictly adhere to the minimum bending radius to prevent severe kinking of the hard-line MI cable, and route it away from heavy power lines to reduce noise pick-up.
What are the basic maintenance requirements for the Vibro-Meter CA306 144-306-000-321?
As a hermetically sealed sensor, the housing requires no internal maintenance, but regular checks for mounting bolt tightness and keeping the connector port perfectly clean and free of dust are necessary.
Why select the Vibro-Meter CA306 144-306-000-321 for extreme conditions where standard sensors fail?
Standard sensors experience depolarization or internal desoldering above +150°C, whereas the CA306 specifically withstands extreme thermal stress to guarantee long-term data reliability.
