Description
The 89477-33 right-angle interconnect cable is a critical enabler for the High Temperature Velomitor System. With a length of 33 feet (10 meters), this integrated cable allows for the physical segregation of the system's two main components. The sensor head, designed to be mounted directly on hot surfaces with temperatures up to +400°C (+752°F), is permanently connected via the 89477-33 cable to the signal conditioning electronics.

By utilizing the 89477-33 cable, users can strategically position the sensitive signal conditioning electronics in a cooler, more accessible location. The internal electronics of the Velomitor are rated for an ambient temperature range of -55°C to +121°C (-67°F to +250°F). 

The integration of the 89477-33 cable into the transducer system makes it possible to capture high-fidelity machinery performance data comparable to other Bently Nevada Velomitor velocity transducers, but at significantly elevated surface temperatures. 

In summary, the 89477-33 is not a standalone accessory but an inseparable part of a high-temperature measurement solution. Its 33-foot length, right-angle connection, and permanent integration are key features that allow the Velomitor system to deliver reliable vibration data from environments that would cause conventional sensor electronics to fail.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the primary function of the 89477-33 cable in the Velomitor system?
The 89477-33 is a 33-foot integral interconnect cable that permanently links the high-temperature sensing head to the signal conditioning electronics. Its core function is to enable the physical separation of these components, allowing the head to be mounted on surfaces up to +400°C while the electronics are placed in a cooler location (below +121°C), thereby ensuring system reliability and performance.
Can the 89477-33 cable be disconnected or replaced in the field?
No. The 89477-33 cable is permanently integrated into the transducer assembly (models 330750/330752). This design intentionally eliminates connectors, which are a significant potential failure point in high-temperature environments. The system is supplied as a single, continuous unit from the sensor head through the 89477-33 cable to the electronics housing.
How do I determine if I need the system with the 89477-33 cable or a standard Velomitor sensor?
The key determining factor is the surface temperature at the desired mounting point. If the surface temperature exceeds +121°C (+250°F), you must use the High Temperature Velomitor System with the integrated 89477-33 cable to survive temperatures up to +400°C. If the surface temperature is at or below +121°C, the standard 330500 Velomitor sensor is suitable and typically more cost-effective.
Why is the temperature rating for the electronics connected to the 89477-33 cable limited to +121°C?
The signal conditioning electronics contain sensitive components that cannot withstand the extreme temperatures measured by the sensor head. The -55°C to +121°C range for the electronics is a standard industrial rating for reliable, long-term operation of this circuitry. The 89477-33 cable's length allows users to locate this electronics module away from the heat source, within this safe ambient temperature envelope.
