Quick Detail

Description

The 190501-12-00-00 Velomitor CT Velocity Transducer is a precision piezoelectric sensor engineered for accurate measurement of casing vibration velocity in industrial machinery, particularly cooling tower and air-cooled heat-exchanger fan assemblies. Designed for low-frequency applications, it reliably detects vibration velocities in fans operating from 90 rpm up to 300 rpm, while also capturing higher frequency vibrations from motor and speed reducer interactions. The sensor provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% with a frequency response of 3 Hz to 900 Hz ±1 dB or 1.5 Hz to 1 kHz ±3 dB, ensuring precise dynamic monitoring across a wide operational spectrum. Constructed from 316L stainless steel with a MIL-C-5015 2-pin connector, it delivers durability in harsh industrial environments. The Velomitor CT can be mounted in any orientation on a 33 mm diameter surface, with mounting torque of 4.5 N-m ±0.6 N-m. It operates reliably in temperatures from –40°C to +85°C (–40°F to +185°F) and can withstand 5000 g shock, 100% condensing humidity, and extended storage conditions, making it ideal for long-term vibration monitoring in automated systems. Its robust design ensures high repeatability, low temperature sensitivity (–8% to +5%), and consistent output for integration with industrial monitoring and automation systems.

Applications
