FAQs
Q1: What is the primary function of the 133388-02 module?
It is the main module for the 3500/50 Tachometer. It measures shaft speed, rotor acceleration, and direction of rotation for machinery protection.
Q2: How many channels does the 133388-02 module have?
It is a dual-channel module, capable of monitoring two independent speed inputs.
Q3: What types of sensors are compatible with this module?
It is compatible with standard proximity probes and magnetic pickups.
Q4: Can I use the 133388-02 module by itself?
No. The module must be installed in a 3500 Series rack and requires a specific I/O module (e.g., Internal Termination Block) for field wiring and signal termination.
Q5: Does this module provide overspeed protection?
Bently Nevada explicitly states that this module is designed for speed monitoring, not as a dedicated overspeed protection module. Systems requiring overspeed protection must use modules designed for that specific function.
The Bently Nevada 330105-02-12-05-02-00 is an 8 mm reverse-mount proximity probe from the 3300 XL series, engineered for non-contact vibration and position monitoring in space-constrained machinery.
The Bently Nevada 330130-085-00-00 is an 8.5-meter standard extension cable for the 3300 XL 8 mm Proximity Transducer System. It connects a 3300 XL proximity probe to its Proximitor® sensor, transmitting eddy-current displacement signals for vibration, axial position, and Keyphasor measurements on critical rotating machinery.
The Bently Nevada 21000-00-00-15-030-04-00 is a Proximity Probe Housing Assembly from the 21000 series, designed to provide a secure, environmentally sealed mounting interface for reverse-mount proximity probes on critical rotating machinery.
The Bently Nevada 330780-50-00 is a 5.0-meter Proximitor® Sensor for the 3300 XL 11 mm Proximity Transducer System. It receives signals from a 3300 XL 11 mm probe and its extension cable, conditioning them into a linear voltage output proportional to shaft displacement for radial vibration, axial thrust position, and Keyphasor measurement.
The Bently Nevada 21747-040-00 is a 4-meter Proximitor probe extension cable designed for the 3300 and 7200 Series Proximity Transducer Systems. It connects a proximity probe to its Proximitor sensor, transmitting high-frequency eddy-current displacement signals for vibration and shaft position monitoring on critical rotating machinery.
The Bently Nevada 330710-00-060-10-02-00 is a 3300 XL 11 mm Proximity Probe designed for non-contact vibration and position measurement on large, fluid-film bearing machinery. Its 11 mm tip provides a longer linear range compared to the standard 8 mm system, making it ideal for applications requiring greater measurement span, such as axial thrust position, differential expansion, and radial vibration on steam turbines, centrifugal compressors, and large pumps.
The Bently Nevada 330103-00-11-50-02-00 is a 3300 XL 8 mm proximity probe with a metric M10×1 thread and a 5.0-meter integral cable terminated with a miniature coaxial ClickLoc™ connector. This extended-reach configuration features a 110 mm overall case length and connects directly to a Proximitor® sensor without requiring an extension cable for short-run installations.
The Bently Nevada 990-10-XX-01-00 (MOD 165353-01) is a two-wire, loop-powered Vibration Transmitter designed for OEMs of centrifugal air compressors, small pumps, motors, and fans. It accepts input from a 3300 NSv proximity probe and its matching extension cable, conditioning the signal into a 4–20 mA output proportional to peak-to-peak vibration amplitude.
