Description

The 190501-02-00-04 Velomitor CT Velocity Transducer is a specialized, low-frequency sensor engineered to measure casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies. This configuration features a 3/8-in 24 to 1/2-in 20 mounting stud (Option 02), a standard MIL-C-5015 connection interface (Option 00), and no hazardous area approvals (Option 04). Designed specifically for machinery operating at or above 90 rpm, this piezo-velocity sensor effectively monitors vibration amplitudes generated by the fan motor and speed reducer. It provides critical data for detecting common machine malfunctions such as unbalance and misalignment. For effective machine protection, the transducer should be installed on the bearing housing or machine casing to ensure accurate transmission of rotor vibration to the sensor.

Features

Designed for low-frequency vibration monitoring (100 to 300 rpm typical)
Option 02 mounting: 3/8-in 24 to 1/2-in 20 stud for robust attachment
Option 00 connection: Standard MIL-C-5015 2-pin interface
Option 04: Standard configuration for non-hazardous application environments
316L stainless steel case material for durability in industrial conditions
Output: 100 mV/in/s (3.94 mV/mm/s) sensitivity
Internal electronics isolated from case to prevent ground loops

Applications

Cooling tower fan assemblies
Air-cooled heat exchanger fans
Low-speed rotating machinery vibration monitoring
General casing vibration measurement in industrial environments
