      Product Information:

      Part number 330750-40-05 represents the Bently Nevada High-Temperature Velocity Measurement System. Standard velocity sensors (such as the Bently Nevada 330500) integrate their signal conditioning electronics directly into the sensor body, resulting in a maximum operating temperature threshold of +121°C (+250°F).

      The 330750 system overcomes this bottleneck by separating the core sensor head from the electronics and using integrated hardwired connections. This layout allows the sensor head to be directly mounted on high-temperature mechanical surfaces, while the processing electronics are safely connected to a lower-temperature environment.

      Features:

      • 330750 and 330752 High Temperature Velomitor System
      • Parameters are specified from +20°C to +30°C (+68°F to +86°F) and 100 Hz
      • To 100% non-submerged; case is hermetically sealed
      The 330750 and 330752 High Temperature Velomitor System sensor head and integral cable are designed for high temperature environments. This enables you to mount the sensing head on surfaces with temperatures up to +400°C (+752°F).

      The cable enables you to position the signal conditioning electronics in a cooler location. The internal electronics withstands temperatures of 55°C to +121°C (-67°F to +250°F). The integrated design makes it possible to capture machinery performance data comparable to other Bently Nevada Velomitor transducers, but at significantly higher temperatures.

      The 330750-40-05 Bently Nevada 330750 High Temperature Velomitor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

      When installing the sensor head, ensure it is securely tightened onto the mechanical surface to guarantee an unobstructed acoustic path; loose installation will lower the 5 kHz resonant frequency threshold, leading to signal tracking errors or false high-frequency spikes. The independent electronic component housing features specially designed external threads for seamless mounting to local partition brackets or field protection junction boxes.
