Description

The Vibro-Meter CA202 144-202-000-205 is a heavy-duty piezoelectric accelerometer designed for continuous vibration monitoring of critical rotating machinery in harsh industrial environments. It incorporates a symmetrical shear-mode polycrystalline sensing element with internal case insulation, providing high measurement stability while minimizing the effects of electrical interference, base strain, and thermal variations. The sensor delivers a charge output of 100 pC/g, offers a frequency response of 0.5 Hz to 6 kHz, and measures vibration over a dynamic range of 0.01 g to 400 g peak. Its hermetically sealed austenitic stainless-steel housing and integral low-noise cable protected by a flexible stainless-steel hose ensure reliable operation in environments with high temperatures, moisture, dust, and mechanical stress. The CA202 144-202-000-205 is the standard version with a 3 m integral cable and is intended for use with Vibro-Meter IPC70x series charge converters.
