Wilcoxon Research offers three options for applications in which temperatures are above the normal operating range of industrial accelerometers, greater than 250ºF (120ºC). The FireFET™ series, models 793-6 and 797-6, is designed for continuous operation up to 302ºF (150ºC). These sensors are typically used where extra temperature protection is needed, such as the dryer section of a paper machine.
If an installation is greater than 302ºF, a special type of accelerometer system is necessary. The 376/CC701HT system consists of three parts: sensing accelerometer (376), charge converter (CC701HT) and connecting cable. Using this arrangement, the temperature-sensitive amplifier (charge converter) is removed from the sensor and placed within a separate component outside the intense heat. One end of the charge converter will be connected to the sensor via the supplied cable and the other will be available to connect to analysis or acquisition equipment. As with all "charge mode" sensors, care must be taken to secure the connecting cable when taking data. Movement of this cable may induce false signals (triboloectric effect). |

Various Kistler accelerometers are suitable for use even at the extremes of the measurement range. Miniature models designed for minimal mass loading are still capable of generating a significant signal. Conversely, high sensitivity models are available for testing low amplitude motions down to a complete standstill.
K-Shear® Triaxial TEDS Accelerometer, 500g:
Low impedance voltage mode, low profile design, quartz shear accuracy and stability, hermetically sealed, CE compliant.
Applications
Useful for measuring small and lightweight structures, where mass loading must be kept at a minimum. |

| Wilcoxon Research manufactures a variety of triaxial sensors which consist of three sensing elements within a single housing. These transducers allow for the acquisition of multi-directional data at a single mounting location. Proponents of multi-axial sensors cite the increase speed of data collection, its inherently consistent readings and reduction in wiring for permanent installations. |

The 330400 accelerometer is designed for general-purpose casing acceleration measurements and meets all requirements of API 670. The 330425 is identical except it provides a broader amplitude range (75 g peak) and a sensitivity of 25 mV/g peak. Neither transducer requires an external interface module.
The 330450 HTAS segregates the sensing element from the signal conditioning electronics, with the two permanently connected via a hard-line cable. This allows the sensing head to be mounted on surfaces with temperatures as high as +400°C ( 752°F), while the signal conditioning electronics can be installed in a cooler location.
The 200150 Accelerometer is intended for use only with a compatible Transducer Interface Module (TIM) as part of our Trendmaster® Pro quasi-continuous online condition monitoring system. The accelerometer features a frequency response suitable only for general purpose applications. When machinery with slow rotative speeds will be monitored, use the 200155 and an appropriately configured proTIM instead. For acceleration enveloping applications, use the 200157 and an appropriately configured proTIM. |

Accelerometers can be used to measure vibration, shock, velocity, displacement, tilt and inclination. The Vibration Sensors Business Group spearheads Measurement Specialties' global initiative to focus on the accelerometer and vibration sensing business with customers in the automotive, medical, military/aerospace and consumer goods industries. This group builds on Measurement Specialties' Silicon MEMS, Bonded Strain Gage and Piezoelectric sensing technologies. More than any other sensor company, Measurement Specialties can choose the best possible technology to solve customer problems and achieve high performance at very competitive costs.
Piezoresistive Silicon MEMS & Bonded Strain Gage
Measurement Specialties' experience designing Micro-Electro-Mechanical Systems (MEMS) using silicon structures is unsurpassed in the world. We have developed and commercialized several product areas based on silicon micromachining technology, offering an unmatched range of standard products with a strong custom design capability.
Piezo Film & Ceramic
Measurement Specialties innovative approach for cost-effective piezoelectric accelerometer designs resides in its ability to use a broad range of materials including crystals such as quartz or man-made ceramic and polymers that have piezoelectric properties. OEM manufacturers look towards this technology as it provides lower-cost sensors requiring no external power supply.

The D.Electron 3-axial acceleromter has been designed to be the transducer of a motion control system capable of eliminating unwanted floxures and oscillations of a machine tool.
While the standard position transducer cannot measure the real tool-tip position, it could be the nearer transducer to the tip of the tool.
Novelty of the D.Electron 3-axial accelrometer is the possibility of being connected to any motion control system (not only D.Electron Z32 CNC): its output is coded as a standard encoder output.
The accelerometer has been designed for real-time applications, with extremely fast A/D conversion and maximum output delay below 1 mcro-second. |
