111.01 : Uniaxial Piezo Top (Velocimeter)

General  Characteristics (metric):  Hex 0.8 inch, Height = 2 inch,  weight=3.0 Oz, 120°C, 1/4" 28 UNF thread.

For reliable vibration monitoring in harsh industrial conditions, choose the hermetically sealed piezovelocity transducer model 111. It leverages the industry-proven ICP 2-wire voltage transmission (4 mA constant current) for easy integration. Enjoy accurate, noise-free measurements thanks to isolated signal ground (preventing ground loops) and Faraday shielding (minimizing EMC). Its innovative annular shear design eliminates errors from thermal shock and base strain. Expect consistent, precise data across all operating temperatures due to low-noise electronics and temperature compensation.

Typical applications: 

Although velocity is the preferred measurement for monitoring most rotating machinery with rolling element bearings, deriving it from standard piezoelectric accelerometers can be difficult. High-frequency noise can saturate these accelerometers. Piezovelocity sensors offer a solution by integrating the signal internally, which inherently diminishes high-frequency components and allows for better low-frequency velocity measurements. This makes them particularly advantageous for applications where high-frequency noise is common, such as paper machine dryers with steam leaks and pumps suffering from cavitation.
