Sensors

The 3300 Proximitor Sensor System Series sensors are proven performers in machinery applications around the world, and continue to provide reliable, trouble-free service year after year. As with most of our transducer systems, components are available in a wide range of thread sizes and probe configurations, and with a variety of mounting accessories that you can tailor to your application needs.

The 3300 XL Series Proximitor Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DINrail installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates. The 3300 XL Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings, resulting in lower installation costs and complexity. The 3300 XL’s SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.

Offered in a wide variety of measurement range options, the 3300 XL Series of sensor systems are the best performing and longest lasting sensors available today. Featuring superior performance in a variety of harsh environments, our 3300XL series is offered in 8 mm, 11 mm, 25 mm, or 50 mm versions.

GE Bently Nevada offers a very wide variety of vibration and thrust transmitters, each designed to handle the rigors of industrial environments and many capable of being installed in hazardous areas when appropriate means are used, including the 990/991 Vibration & Thrust Transmitters.

The 990 Vibration Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system. The 991 Thrust Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional axial displacement (thrust) signal as the input to their machinery control system.

Features and Benefits

The features of the 990 Vibration Transmitter include:

• Integrated Proximitor* Sensor requires no external unit
• Non-isolated “PROX OUT” and “COM” terminals plus a coaxial connector to provide a dynamic vibration and gap voltage signal output
• for diagnostics.
• Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
• Test Input pin for quick verification of loop signal output, using a function generator as the input.
• A Power-up Inhibit circuit eliminates signal errors due to line voltage transients.
• A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection.
• Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.
• Potted construction for high humidity (up to 100% condensing) environments.
• Compatibility with 3300 NSv proximity probe allows transducer installation in small areas with minimal clearance, typical of centrifugal air compressors.

The 991 transmitter provides the following notable features:

• Integrated Proximitor* Sensor requires no external unit
• Non-isolated “PROX OUT ” and “COM” terminals plus a coaxial connector provide a dynamic vibration and gap voltage signal output
• for diagnostics.
• Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
• Test Input pin allows quick verification of loop signal output, using a variable DC voltage source as the input.
• A Power-up Inhibit circuit eliminates signal errors due to line voltage transients.
• A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection.
• Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.
• Potted construction for high humidity (up to 100% condensing) environments.
• Compatibility with 3300 NSv proximity probe allows transducer installation in small areas with minimal clearance, typical of centrifugal air compressors.
