Description

The 190501-19-00-04 is a Velomitor CT Velocity Transducer engineered for low-frequency vibration monitoring on cooling towers and air-cooled heat-exchanger fan assemblies. This specific configuration features a 3/8-24 to 1/4-18 NPT adapter (Option 19), a standard MIL-C-5015 connection interface (Option 00), and is certified with CSA/NRTL/C and ATEX/IECEx approvals (Option 04). This transducer is a low-frequency variant of the standard Velomitor Piezo-velocity sensor, optimized for machines operating at or above 90 rpm. It effectively measures casing vibration velocity, capturing critical data on rotor-related malfunctions such as unbalance and misalignment. The transducer should be installed on the machine casing or bearing housing to ensure accurate transmission of rotor vibration.

Features

Designed for low-frequency applications (100 to 300 rpm typical, 90 rpm minimum)
MIL-C-5015 connection interface for robust electrical termination
3/8-24 to 1/4-18 NPT mounting adapter for versatile installation
Certified for hazardous area use (CSA/NRTL/C Class I, Division 1 and ATEX/IECEx Class I, Zone 0/1)
316L stainless steel housing for environmental durability
Broad operating temperature range from -40 degC to +85 degC
Internal electronics isolated from case to prevent ground loops

Applications

Cooling tower fan assemblies
Air-cooled heat exchangers
Low-speed rotating machinery vibration monitoring
Casing vibration measurement for machine protection
