Description

The 190501-12-00-01 is a Bently Nevada Velomitor CT Velocity Transducer specifically configured with Option 12 (Stud M6x1 with 3/8-in 24 adapter), Option 00 (MIL-C-5015 connection interface), and Option 01 (Agency Approvals: CSA/NRTL/C, ATEX/IECEX/CSA). This low-frequency piezo-velocity sensor is designed to measure casing vibration velocity on machinery such as cooling towers and air-cooled heat-exchanger fan assemblies. It provides consistent monitoring for equipment typically operating at or above 90 rpm, capturing vibration frequencies relevant to both the rotor and the associated speed reducer or fan motor. As part of the 3300-compatible monitoring ecosystem, this transducer is constructed with a 316L stainless steel case to withstand harsh industrial environments. Proper installation on the bearing housing or machine casing is essential to ensure accurate signal transmission and to avoid false readings caused by improper mounting. This unit features internal isolation of electronics from the case, minimizing ground loop interference in complex machinery protection installations.

Features

Option 12 Mounting: Includes Stud M6x1 with 3/8-in 24 adapter for versatile mechanical attachment.
Option 00 Connection: Standard MIL-C-5015 connection interface for robust, industry-standard cabling.
Option 01 Certification: Agency approved for CSA/NRTL/C (Class I, Division 1) and ATEX/IECEX/CSA (Class I, Zone 0/1) hazardous area installations.
Low-frequency response optimized for 3 Hz to 900 Hz range (at 1.0 dB).
316L stainless steel housing for durability and corrosion resistance.
Electrically isolated internal electronics from the transducer case.
Compatible with standard 2-pin MIL-C-5015 cable assemblies.

Applications

Cooling tower fan assemblies
Air-cooled heat exchangers
Low-speed rotating machinery (90 rpm and above)
Machine casing vibration monitoring
General industrial vibration protection where low-frequency accuracy is required

Installation Guidelines

Install the transducer directly on the bearing housing or machine casing to maintain frequency response.
Use the provided mounting adapter (Option 12: M6x1 to 3/8-in 24) and tighten to a mounting torque of 4.5 N-m +/- 0.6 N-m.
Ensure the cable is properly secured to prevent mechanical stress on the MIL-C-5015 connector.
For hazardous area installations (Option 01), follow the specific requirements outlined in drawing 167536.
Verify that the mounting location provides a direct path for rotor vibration to ensure effective machine protection.
