PRODUCT DESCRIPTION
Low frequency velocity transducer
Bently Nevada 190501-12-00-02 is a low-frequency velocity transducer. The low-frequency velocity transducer measures casing vibration on cooling-tower and air-cooled heat-exchanger fan assemblies. It supports documented applications operating at or above ninety revolutions per minute, including vibration associated with the fan motor and speed reducer.
Match the complete mounting-hardware, connection and approval options with the installed assembly. Confirm that the relevant rotor vibration is transmitted to the chosen casing location. Unresolved ordering fields or modifications require confirmation before the transducer is selected as a replacement.

LOW FREQUENCY VELOCITY TRANSDUCER
Integrating 190501-12-00-02
The low-frequency velocity transducer measures casing vibration on cooling-tower and air-cooled heat-exchanger fan assemblies. It supports documented applications operating at or above ninety revolutions per minute, including vibration associated with the fan motor and speed reducer.
Use a monitoring input that accepts the specified Velomitor CT sensitivity, bias and signal interface. The transducer measures casing velocity, not shaft-relative displacement. Its low-frequency application range does not make every general-purpose velocity or acceleration input interchangeable.
Use the documented mounting hardware and 4.5 +/-0.6 N m torque. The transducer can operate in any orientation, but the selected axis and rigid mounting must represent the vibration of interest. Incorrect installation can change amplitude or frequency response.
Features:
- Match complete ordering options, sensing-chain configuration, mounting and target arrangement
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 190501-12-00-02 low-frequency velocity transducer requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 190501-12-00-02 requires comparing complete ordering options, sensing-chain configuration, mounting and target arrangement. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Use a monitoring input that accepts the specified Velomitor CT sensitivity, bias and signal interface. The transducer measures casing velocity, not shaft-relative displacement. Its low-frequency application range does not make every general-purpose velocity or acceleration input interchangeable.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 190501-12-00-02 low-frequency velocity transducer requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 190501-12-00-02
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What type of transducer is 190501-12-00-02?
Match the complete mounting-hardware, connection and approval options with the installed assembly. Confirm that the relevant rotor vibration is transmitted to the chosen casing location. Unresolved ordering fields or modifications require confirmation before the transducer is selected as a replacement. -
What does the Velomitor CT measure?
The low-frequency velocity transducer measures casing vibration on cooling-tower and air-cooled heat-exchanger fan assemblies. It supports documented applications operating at or above ninety revolutions per minute, including vibration associated with the fan motor and speed reducer. -
Which signal input is compatible?
Use a monitoring input that accepts the specified Velomitor CT sensitivity, bias and signal interface. The transducer measures casing velocity, not shaft-relative displacement. Its low-frequency application range does not make every general-purpose velocity or acceleration input interchangeable. -
Which fan systems are documented applications?
The manufacturer states that the transducer also measures frequencies generated by the fan motor and speed reducer. Mount the sensor where these motions are effectively transmitted rather than assuming every casing location provides an equivalent signal. -
What mounting precautions apply?
Use the documented mounting hardware and 4.5 +/-0.6 N m torque. The transducer can operate in any orientation, but the selected axis and rigid mounting must represent the vibration of interest. Incorrect installation can change amplitude or frequency response. -
What is the stated minimum fan operating speed?
The manufacturer identifies fan assemblies operating at or above 90 rpm, with 100-300 rpm typical. Check the complete frequency and amplitude limits; speed alone does not validate every measurement condition. -
Can high-frequency vibration affect the velocity range?
Yes. The stated 63.5 mm/s peak range can be significantly reduced by vibration components above 10 g peak at frequencies above 1 kHz. Review the operating-range diagrams and actual machine spectrum.
