  • 200150 SERIES ACCELEROMETERS

    The 20015x Accelerometers are general purpose, wide frequency, case-mounted seismic transducers designed for use with Trendmaster* proTIMs. The 200150 Series Accelerometers also operates with the Trendmaster2000 system. The accelerometer interfaces with the 200100 Dual Acceleration to Velocity flexiTIM* Module and the 89130-01 Acceleration-to-Velocity TIM (Transducer Interface Module), as well as the 1900/25 and 1900/27 monitors. The 20015x Accelerometers feature a hermetically sealed, stainless steel case. This design provides an extremely rugged transducer that is well suited for harsh industrial environments. The transducer’s top-mounted, 5-pin connector allows you to easily install and remove the interconnecting signal cable. A 3/8-24 threaded hole on the bottom of the sensor’s casing accommodates several mounting options. The 20015x Accelerometers contain a piezoelectric sensing device that generates a charge when it is subjected to vibration. The accelerometers electronically convert this charge to a differential voltage signal that is proportional to the acceleration that is parallel to the sensitive axis of the transducer.

    Application Advisories

    1. Use of the 200155 and 200157 Accelerometers with 1900 monitors or with TIMs other than those listed in Table 1 will result in false readings.

    2. Operating the transducers outside their specified limits will result in false readings or loss of machine monitoring.

    3. The maximum allowed cable length for use with the 200155 is 50 feet.

    4. 20015x accelerometers may be installed in a Class I, Zone 0 application without a barrier, if they are being used with the wSIM.

  • 3300-XL-Series-Proximitor-System

    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.

  • 990/991-VIBRATION-THRUST-TRANSMITTERS

    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.

  • high-temperature-velocity-and-acceleration-sensor

    The 330750 and 330752 High Temperature Velomitor System (HTVS) has a design that segregates the sensing element from the signal conditioning electronics, with the two permanently connected via a hardline cable. Due to the segregated design, the signal conditioning electronics can be installed in a cooler location. This achieves overall transducer system performance comparable to other Velomitor transducers, but permits use at significantly higher temperatures. By eliminating connections between the sensing head and its associated signal conditioning electronics, a significant source of potential transducer failures (connector problems) is eliminated.
