Description：

The Vibro-Meter CA303 144-303-000-011 Piezoelectric Accelerometer is a high-temperature vibration sensor used for continuous monitoring of gas turbines and other critical rotating machinery operating in demanding industrial environments. The sensor provides a differential charge output and delivers a sensitivity of 50 pC/g, allowing accurate measurement of vibration levels across a wide operating range.

The CA303 series supports continuous operation at temperatures up to 455°C (850°F) and utilizes a rugged Inconel 600 hermetically welded housing for excellent resistance to heat, corrosion, humidity, and mechanical stress. An integral mineral-insulated cable with stainless-steel overbraid helps maintain signal integrity in harsh environments commonly found in gas turbines and power generation facilities.
