The CTC AC214 Series is purpose-engineered for assets where every micro-g of vibration matters—slow-turning main shafts, large sleeve bearings, or lightly loaded gear stages whose fault energy can be vanishingly small. By delivering a market-leading sensitivity of 1000 mV/g (10× the output of standard IEPE probes) and a flat response from 0.1 Hz to 10 kHz (±3 dB), the AC214 extracts usable data from motions that would disappear into the noise floor of ordinary sensors, yet still captures the ultrasonic signatures of early bearing or gear defects. A shear-mode PZT element is hermetically welded inside a compact 316 L stainless-steel housing for long-term stability, excellent thermal behavior, and full submersibility, all in a package weighing just 92 g.
Because high sensitivity often implies fragility, the AC214 is instead rated for ±7 g dynamic range and a 5 000 g shock limit, allowing it to survive heavy knocks during installation and operation. The top-exit MIL-5015 connector (or optional shielded / armored integral cable) streamlines cable routing in cramped nacelles and enclosures, while the sensor’s IEPE electronics settle in under two seconds for rapid field checks. Backed by CTC’s unconditional lifetime warranty, the AC214 combines laboratory-grade resolution with true industrial toughness.
