Quick Detail

Description

The 190501-07-00-04 Velomitor CT Velocity Transducer is a high-precision seismic sensor specifically engineered by Bently Nevada to monitor the vibration levels of cooling tower fans and other low-speed industrial machinery. As a specialized version of the standard Velomitor, the 190501-07-00-04 Velomitor CT Velocity Transducer is optimized for the unique frequency requirements of cooling tower applications, providing a robust interface between rotating equipment and plant monitoring systems. This Velomitor CT Velocity Transducer converts vibration velocity into a proportional 4-20 mA electrical signal, allowing for direct integration with Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC) without the need for additional signal conditioners.

Designed for longevity in extreme environments, the 190501-07-00-04 Velomitor CT Velocity Transducer features a 316L stainless steel housing that offers superior resistance to the corrosive mist and high humidity typical of cooling tower cells. The Velomitor CT Velocity Transducer utilizes a MIL-C-5015 connection interface, ensuring a secure and weatherproof electrical link even under constant mechanical oscillation. With its 0 to 24.4 mm/s (0 to 1.0 in/s) peak linear range, the 190501-07-00-04 model provides accurate data for early detection of balance issues, gear fatigue, or structural resonance.

Safety is paramount in industrial operations; thus, the 190501-07-00-04 Velomitor CT Velocity Transducer carries multiple international certifications, including ATEX, IECEx, and CSA approvals for Class I, Division 1 and Zone 0/1 hazardous locations. The Velomitor CT Velocity Transducer's 4-wire loop-powered design simplifies field wiring and reduces installation costs. By implementing the 190501-07-00-04, operators can transition from reactive to predictive maintenance strategies, effectively extending the service life of critical cooling assets. This Velomitor CT Velocity Transducer remains the industry standard for reliable, non-contact vibration monitoring in the most challenging wet and volatile industrial cooling environments

Applications

The 190501-07-00-04 Velomitor CT Velocity Transducer is primarily designed for the vibration monitoring of large-scale industrial cooling tower fans. Given the low rotational speeds of these fans, the sensor is tuned to capture low-frequency seismic data that standard sensors might miss. It is frequently installed on the gearbox or fan motor housing to detect mechanical looseness, blade imbalance, or misalignment. By providing a constant 4-20 mA output, it allows real-time tracking of vibration trends directly via a PLC, ensuring that any deviation from normal operating parameters triggers an immediate alert before a catastrophic failure occurs.

In the power generation and petrochemical sectors, this velocity transducer is an essential tool for monitoring heat exchangers and air-cooled condensers (ACC). The 190501-07-00-04 thrives in these "wet" environments thanks to its hermetically sealed 316L stainless steel casing and NPT fittings. Its ability to operate reliably in a temperature range of -45°C to +75°C makes it suitable for both outdoor installations in frigid climates and high-temperature process zones. It ensures that critical cooling infrastructure remains functional, preventing thermal inefficiencies that could lead to broader plant shutdowns.

The transducer is also extensively used in hazardous industrial zones where explosive gases may be present. Because the 190501-07-00-04 is CSA, ATEX, and IECEx certified for Class I, Division 1 areas, it is the ideal choice for refineries and chemical processing plants. It can be integrated into wide-area machinery protection systems using 4-wire field wiring over distances up to 305 meters. Whether monitoring a slow-turning agitator in a chemical tank or a cooling fan on an offshore platform, this sensor provides the high-fidelity velocity data required for rigorous API 670 compliant machinery protection.

Specifications

Competitive Advantage

1. Specialized Low-Frequency Tuning for Cooling Towers

Unlike general-purpose vibration sensors, the 190501-07-00-04 is specifically "CT" (Cooling Tower) rated. It is engineered with an internal circuit optimized for the low-frequency vibrations typical of large, slow-moving fan blades. This specialized tuning prevents "noise" interference from higher-frequency nearby equipment, ensuring that the data collected is accurate and relevant only to the specific cooling tower component being monitored.

2. Robust 316L Stainless Steel & Weatherproof Construction

The transducer features a rugged 316L stainless steel body and a hermetically sealed design that provides a "Type 4" enclosure rating. This makes it exceptionally resistant to the corrosive chemicals, high moisture, and constant water spray found in cooling tower cells. Coupled with the MIL-C-5015 connector and NPT plug fittings, the 190501-07-00-04 offers a level of environmental protection that significantly outlasts standard aluminum-bodied sensors in humid conditions.

3. Simplified Integration and Hazardous Area Certification

One of the key advantages of the 190501-07-00-04 is its 4-20 mA loop-powered output, which eliminates the need for expensive external Proximitor* or signal interface modules. It can be wired directly into existing control systems, reducing total installation costs by up to 40%. Furthermore, its comprehensive suite of global safety approvals (ATEX/IECEx/CSA) allows for universal deployment in hazardous environments without the need for additional explosion-proof housings.
