Overview Manuals Specifications

Features:

  • Right angle interconnect cable for High Temperature Velomitor System
  • Permanently connects +400°C sensor head to cooler electronics
  • Connectorless design eliminates failure points in extreme environments
The 89477-27 provides essential signal connection functions critical to the entire monitoring path, serving as the vital link between the high-temperature sensing head and the signal conditioning electronics, directly affecting the proper, normal operation of the overall vibration monitoring system. One 89477-27 cable is required per measurement point, permanently connecting the sensor head mounted on hot surfaces to the remotely located electronics module.

The 3500/15 provides essential power functions common to the entire rack, and is a critical For applications requiring physical separation between sensing and electronics, the 89477-27 enables positioning of the signal conditioning electronics in a cooler location while the sensing head remains exposed to temperatures up to +400°C. In addition to standard signal transmission, the right angle configuration of the 89477-27 facilitates routing in tight spaces and helps protect the cable from sharp bends that could compromise signal integrity.

The 89477-27's robust construction ensures reliable operation in demanding high-temperature environments. Using integral hardline materials rated for extreme thermal conditions, the cable maintains signal integrity over its entire length. The integrated design of the 89477-27 makes it possible to capture machinery performance data comparable to other Bently Nevada Velomitor transducers, but at significantly higher temperatures.

The 89477-27 Bently Nevada Right angle interconnect cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Model 89477-27 is a specialized right angle interconnect cable engineered as an integral component of the 330750 and 330752 High Temperature Velomitor System, designed for vibration monitoring in extreme thermal environments. This 27-foot cable permanently connects the sensor head, which can be mounted on surfaces up to +400°C (+752°F), to the signal conditioning electronics that must be located in a cooler area. 

The physical separation capability provided by the 89477-27 is critical for applications involving gas turbine casings, high-temperature steam lines, and other heat-intensive machinery. By utilizing the 27-foot length of the 89477-27, installers can position the sensitive signal conditioning electronics in environments within the -55°C to +121°C (-67°F to +250°F) operating range while the sensing head remains exposed to extreme heat. 

The integrated design philosophy embodied in the 89477-27 represents a significant advancement over systems requiring separate connectors and extension cables. Each 89477-27 is factory-terminated and tested as a complete assembly, ensuring consistent performance and eliminating field installation errors that can affect measurement accuracy. 

The 89477-27 enables the High Temperature Velomitor System to deliver reliable vibration data from environments that would cause conventional transducer electronics to fail. When specified for a high-temperature monitoring point, the 89477-27 cable length must be carefully considered based on the distance between the hot measurement spot and a viable cooler location for the electronics module.
