Description
The Bently Nevada 330750-40-05 High Temperature Velomitor System is a velocity vibration sensor designed for continuous monitoring of casing vibration on rotating machinery operating in extreme-temperature environments.
Unlike conventional velocity sensors, the 330750 system separates the sensing head from the signal conditioning electronics through an integral hardline cable, allowing the sensing element to be installed on surfaces with temperatures up to +400°C (+752°F).

Features:
- High-temperature Velomitor system sensor head with integral cable
- 4-meter integrated cable length
- Multiple hazardous area approvals
- Sensor head with 25.4 mm (1.00 in) diameter and 1-inch NPT mounting
To accomplish this, the transducer design segregates thesensing element from the signal conditioning electronics. Thetwo are permanently connected using an integrated cable.The integrated cable eliminates connectors which are asignificant source of transducer failures.
The cable enables you to position the signal conditioningelectronics in a cooler location. The internal electronicswithstands temperatures of 55°C to +121°C (-67°F to +250°F).The integrated design makes it possible to capturemachinery performance data comparable to other BentlyNevada Velomitor transducers, but at significantly highertemperatures.
The 330750-40-05 Bently Nevada High Temperature Velomitor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 330750-40-05 is configured with a 4.0 metre (13.1 feet) integral hardline cable and carries multiple hazardous area approvals including CSA (North America) and ATEX (Europe). The sensing head and cable are rated for continuous operation from -55 °C to +400 °C (-67 °F to +752 °F), while the internal electronics operate from -55 °C to +121 °C (-67 °F to +250 °F).
The system delivers a sensitivity of 5.7 mV/mm/s (145 mV/in/s) with ±5% accuracy. The frequency response extends from 15 Hz to 2000 Hz (900 to 120,000 cpm) with ±3.0 dB deviation, and from 20 Hz to 1000 Hz (1,200 to 60,000 cpm) with ±0.9 dB deviation. The amplitude linearity is ±2% up to 152 mm/s (6 in/s) peak, with a maximum amplitude range of 635 mm/s (25 in/s) peak below 680 Hz, or 2940 m/s² (300 g) peak above 680 Hz. The mounted resonant frequency exceeds 5 kHz.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Material Composition: The system is factory-calibrated exclusively for AISI 4140 steel. Alternate metals will alter the linear range and voltage curve.
Minimum Target Diameter: The observed shaft collar or flat target face must be at least 102 mm (4.0 inches) in diameter to fully capture the eddy current loop.

FAQs
-
How does this differ from the standard 330500 Velomitor?
+Standard Velomitors contain their signal conditioning electronics in the same case as the sensing element, limiting their maximum operating temperature to +121°C (+250°F). The 330750 segregates the sensing head from the electronics via a hardline integrated cable, allowing the sensor itself to endure +400°C. -
What is the maximum distance I can place the electronics from the sensor head?
+The integrated cable allows you to route the signal conditioning electronics to a cooler location, and the total cable length can be up to 305 meters (1000 feet) with no signal degradation. -
Which Bently Nevada monitors are compatible with this transducer?
+The 330750 Velomitor System is compatible with the 3300/55 Dual Velocity Monitor (when the -05 transducer option is selected), the 3500/42 Proximitor/Seismic Monitor Module, and the 2201/03-02 and 2201/03-03 monitors. -
How are the sensor head and electronics connected?
+They are permanently connected via an integrated, hardline cable. This integrated design eliminates connectors between the head and electronics, removing a common point of failure.
