Overview

The 330752-25-CN is a High Temperature Velomiter System from Bently Nevada. It is part of Bently Nevada's industrial automation product portfolio.

Application & Technical Notes

As a high temperature velomiter system, the 330752-25-CN is intended for deployment in panel-based control cabinets and machine enclosures where the Bently Nevada product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Bently Nevada platform.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Avoid condensation — the rated humidity is To 100% non-submerged;; store and operate the module in a dry, pollution-degree-appropriate enclosure. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 330752-25-CN, distinguish three supply tiers: (1) genuine Bently Nevada stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your Bently Nevada product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications

330752-25-CN | Bently Nevada | High Temperature Velomiter System

Description

Note	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). Earlier versions of the 330750 and 330752 High Temperature Velomitor System were limited to environments with a maximum temperature of +300°C (+572°F). The serial number of current versions that measure up to +400°C (+752°F) are preceded by the letter "G". To accomplish this, the transducer design segregates the sensing element from the signal conditioning electronics. The two are permanently connected using an integrated cable. The integrated cable eliminates connectors which are a significant source of transducer failures. 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. For lower temperature environments, use the standard 330500 Velomitor Piezo-velocity Sensor. You can install it in locations with a maximum operating temperature of +121°C (+250°F). Electrical Sensitivity 5.7 mV/mm/s (145 mV/in/s) ±5% Frequency Response 15 to 2000 Hz (900 to 120,000 cpm) ± 3.0 dB; 20 to 1000 Hz (1,200 to 60,000 cpm) ± 0.9 dB Transient Temperature Sensitivity 0.0762 mm/s/°C (0.003 in/s/°C), typical, as defined in ISO 5347-18:1993(E) Amplitude Range 635 mm/s (25 in/s) peak below 680 Hz. 2940 m/s2 (300 g) peak above 680 Hz.
