Quick Detail

Description

The 190501-09-99-05 Velomitor CT Velocity Transducer is a high-performance low-frequency piezo-velocity sensor specifically engineered for industrial automation and machinery monitoring. Designed for cooling tower and air-cooled heat-exchanger fan assemblies operating at or above 90 rpm, the sensor provides precise measurement of casing vibration velocity and vibration amplitudes generated by the fan motor and speed reducer. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, frequency response from 3 Hz to 900 Hz (±1.0 dB) or 1.5 Hz to 1.0 kHz (±3.0 dB), and a robust 316L stainless steel housing, it ensures accurate and reliable readings under extreme environmental conditions. The transducer is CSA/NRTL/C and ATEX/IECEx certified for hazardous locations, operates from -40°C to +85°C, and withstands shocks up to 5000 g pk. Its top-mounted 2-pin MIL-C-5015 connector, plate stud mounting, and compatibility with 32-foot cables simplify installation and integration into automated monitoring systems. This Velomitor CT Transducer supports predictive maintenance, real-time vibration monitoring, and machinery health management, delivering superior performance in automation and industrial monitoring applications.
