Description

The 190501-01-00-01 is a Velomitor CT Velocity Transducer configuration featuring a 3/8-in 24 to 3/8-in 24 mounting stud (Option 01), a standard MIL-C-5015 connection interface (Option 00), and CSA/ATEX/IECEx hazardous area approval (Option 01). This device serves as a low-frequency, piezo-velocity sensor used primarily for measuring casing vibration velocity on machinery such as cooling tower fans and air-cooled heat-exchanger assemblies that operate at or above 90 rpm.

By utilizing a piezo-velocity design, this transducer enables continuous monitoring of vibration amplitudes at frequencies common to fan motors and speed reducers. This configuration is encased in 316L stainless steel to resist industrial environmental factors. It is critical to ensure installation on the bearing housing or machine casing for optimal signal transmission, as improper mounting may affect frequency response and amplitude measurement accuracy.

Features

Mounting (Option 01): Includes 3/8-in 24 to 3/8-in 24 mounting stud for direct attachment.
Connection (Option 00): MIL-C-5015 connection interface, 2-pin 316L stainless steel design.
Approvals (Option 01): CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx (Class I, Zone 0/1).
Velocity Range: 63.5 mm/s pk (2.5 in/s pk).
Housing Material: 316L stainless steel construction for durability.
Operating Temperature: -40 C to +85 C (-40 F to +185 F).
Sensitivity: 3.94 mv/mm/s (100 mv/in/s) at 100 Hz.

Applications

Cooling tower fan assemblies
Air-cooled heat exchanger fan assemblies
Low-frequency vibration monitoring (90 rpm and above)
Rotating machinery casing vibration

Installation Guidelines

Install the transducer on the bearing housing or machine casing; avoid non-rigid mounting locations.
Torque the mounting stud to 4.5 N-m (40 in-lbf) to maintain consistent signal path.
Ensure the cable is properly shielded and routed away from high-noise interference sources.
For hazardous areas, follow installation drawings provided with the hazardous area certification documentation.
Check for proper grounding; the internal electronics are isolated from the stainless steel case.
